UPDATE 2021  As shown recently by a new Github repository  webrtc-ip  you can now leak a user s public IP address using WebRTC  Sadly  this leak does not work for private IPs  due to the gradual shift to mDNS  at least for WebRTC   completely explained here  However  here s a working demo   x000D   x000D  getIPs   then res   gt  document write res join   n     x000D   lt script src  https   cdn jsdelivr net gh joeymalvinni webrtc-ip dist bundle dev js  gt  lt  script gt  x000D   x000D   x000D   The compiled source code for this repository can be found here       Previously  Final Update This solution would not longer work because browsers are fixing webrtc leak  for more info on that read this other question  RTCIceCandidate no longer returning IP  Update  I always wanted to make a min  uglified version of the code  so here is an ES6 Promise code   x000D   x000D  var findIP   new Promise r  gt  var w window a new  w RTCPeerConnection  w mozRTCPeerConnection  w webkitRTCPeerConnection   iceServers      b     gt    a createDataChannel     a createOffer c  gt a setLocalDescription c b b  b  a onicecandidate c  gt  try c candidate candidate match    0-9  1 3     0-9  1 3   3   a-f0-9  1 4    a-f0-9  1 4   7   g  forEach r  catch e          Usage example   findIP then ip   gt  document write  your ip     ip   catch e   gt  console error e   x000D   x000D   x000D   Note  This new minified code would return only single IP if you want all the IPs of the user  which might be more depending on his network   use the original code     thanks to WebRTC  it is very easy to get local IP in WebRTC supported browsers  at least for now   I have modified the source code  reduced the lines  not making any stun requests since you only want Local IP  not the Public IP  the below code works in latest Firefox and Chrome  just run the snippet and check for yourself   x000D   x000D  function findIP onNewIP        onNewIp - your listener function for new IPs   var myPeerConnection   window RTCPeerConnection    window mozRTCPeerConnection    window webkitRTCPeerConnection    compatibility for firefox and chrome   var pc   new myPeerConnection  iceServers            noop   function           localIPs           ipRegex      0-9  1 3     0-9  1 3   3   a-f0-9  1 4    a-f0-9  1 4   7   g      key     function ipIterate ip        if   localIPs ip   onNewIP ip       localIPs ip    true        pc createDataChannel        create a bogus data channel   pc createOffer function sdp        sdp sdp split   n   forEach function line          if  line indexOf  candidate    lt  0  return        line match ipRegex  forEach ipIterate               pc setLocalDescription sdp  noop  noop        noop      create offer and set local description   pc onicecandidate   function ice      listen for candidate events     if   ice     ice candidate     ice candidate candidate     ice candidate candidate match ipRegex   return      ice candidate candidate match ipRegex  forEach ipIterate             var ul   document createElement  ul    ul textContent    Your IPs are    document body appendChild ul    function addIP ip      console log  got ip     ip     var li   document createElement  li      li textContent   ip    ul appendChild li      findIP addIP   x000D   lt h1 gt  Demo retrieving Client IP using WebRTC  lt  h1 gt  x000D   x000D   x000D   what is happening here is  we are creating a dummy peer connection  and for the remote peer to contact us  we generally exchange ice candidates with each other  And reading the ice candidates  from local session description and onIceCandidateEvent  we can tell the IP of the user  where I took code from -- gt  Source

There isn t really a reliable way to get the client computer s IP address   This goes through some of the possibilities  The code that uses Java will break if the user has multiple interfaces   http   nanoagent blogspot com 2006 09 how-to-find-evaluate-remoteaddrclients html  From looking at the other answers here it sounds like you may want to get the client s public IP address  which is probably the address of the router they re using to connect to the internet  A lot of the other answers here talk about that  I would recommend creating and hosting your own server side page for receiving the request and responding with the IP address instead of depending on someone else s service that may or may not continue to work

You can use the api service from telize  If you need just the public ip of client  do this    var ip    http   www telize com ip   var response   http request  url  ip      and if you want more details like location and stuff  you can do this    var ipAndGeoDetails    http   www telize com geoip   var response   http request  url  ipAndGeoDetails         NOTE   The public API of telize will permanently shut down on November 15th  2015

There are two interpretations to this question   Most folks interpreted  Client IP  to mean the Public IP Address that Web server s see outside the LAN and out on the Internet   This is not the IP address of the client computer in most cases  though  I needed the real IP address of the computer that is running the browser that is hosting my JavaScript software  which is almost always a local IP address on a LAN that is behind something that NAT layer      Mido posted a FANTASTIC answer  above  that seems to be the only answer that really provided the IP address of the client   Thanks for that  Mido   However  the function presented runs asynchronously   I need to actually USE the IP address in my code  and with an asynchronous solution  I might try to use the IP address before it is retrieved learned stored   I had to be able to wait on the results to arrive before using them   Here is a  Waitable  version of Mido s function   I hope it helps someone else    x000D   x000D  function findIP onNewIP        onNewIp - your listener function for new IPs x000D      var promise   new Promise function  resolve  reject    x000D          try   x000D              var myPeerConnection   window RTCPeerConnection    window mozRTCPeerConnection    window webkitRTCPeerConnection    compatibility for firefox and chrome x000D              var pc   new myPeerConnection   iceServers         x000D                  noop   function         x000D                  localIPs       x000D                  ipRegex      0-9  1 3     0-9  1 3   3   a-f0-9  1 4    a-f0-9  1 4   7   g  x000D                  key  x000D              function ipIterate ip    x000D                  if   localIPs ip   onNewIP ip   x000D                  localIPs ip    true  x000D                x000D              pc createDataChannel        create a bogus data channel x000D              pc createOffer function  sdp    x000D                  sdp sdp split   n   forEach function  line    x000D                      if  line indexOf  candidate    lt  0  return  x000D                      line match ipRegex  forEach ipIterate   x000D                      x000D                  pc setLocalDescription sdp  noop  noop   x000D                 noop      create offer and set local description x000D   x000D              pc onicecandidate   function  ice      listen for candidate events x000D                  if  ice  amp  amp  ice candidate  amp  amp  ice candidate candidate  amp  amp  ice candidate candidate match ipRegex     x000D                      ice candidate candidate match ipRegex  forEach ipIterate   x000D                    x000D                  resolve  FindIPsDone    x000D                  return  x000D                 x000D            x000D          catch  ex    x000D              reject Error ex    x000D            x000D            New Promise              x000D      return promise  x000D     x000D   x000D    This is the callback that gets run for each IP address found x000D  function foundNewIP ip    x000D      if  typeof window ipAddress      undefined   x000D        x000D          window ipAddress   ip  x000D        x000D      else x000D        x000D          window ipAddress      -     ip  x000D        x000D    x000D   x000D    This is How to use the Waitable findIP function  and react to the x000D    results arriving x000D  var ipWaitObject   findIP foundNewIP             Puts found IP s  in window ipAddress x000D  ipWaitObject then  x000D      function  result    x000D          alert   IP s  Found   Result       result       You can use them now      window ipAddress  x000D         x000D      function  err    x000D          alert   IP s  NOT Found   FAILED       err  x000D        x000D     x000D   x000D   x000D    x000D   x000D      x000D   lt h1 gt Demo  Waitable  Client IP Retrieval using WebRTC  lt  h1 gt  x000D   x000D   x000D

Get your IP with jQuery  you can get your public IP address with one line of JS  There is a free service that offers this for you and a get request is all that you need to do        get  http   jsonip com    function r   console log r ip         For the above snippet to work  your browser will have to support CORS  cross-origin request sharing   Otherwise a security exception would be thrown  In older browsers  you can use this version  which uses a JSON-P request        getJSON  http   jsonip com  callback     function r   console log r ip

You could do this entirely client side and mostly in JavaScript by using a Flash object that the js can call  Flash can access the IP address of the local machine which might not be very useful

The simple solution to get the ip address is add the following code in your file       getJSON  https   api ipify org format json   function data          Your callback functions like         console log data ip       localStorage setItem  ip  data ip       alert data ip            It will get the ip address when page loads

There are two interpretations to this question   Most folks interpreted  Client IP  to mean the Public IP Address that Web server s see outside the LAN and out on the Internet   This is not the IP address of the client computer in most cases  though  I needed the real IP address of the computer that is running the browser that is hosting my JavaScript software  which is almost always a local IP address on a LAN that is behind something that NAT layer      Mido posted a FANTASTIC answer  above  that seems to be the only answer that really provided the IP address of the client   Thanks for that  Mido   However  the function presented runs asynchronously   I need to actually USE the IP address in my code  and with an asynchronous solution  I might try to use the IP address before it is retrieved learned stored   I had to be able to wait on the results to arrive before using them   Here is a  Waitable  version of Mido s function   I hope it helps someone else    x000D   x000D  function findIP onNewIP        onNewIp - your listener function for new IPs x000D      var promise   new Promise function  resolve  reject    x000D          try   x000D              var myPeerConnection   window RTCPeerConnection    window mozRTCPeerConnection    window webkitRTCPeerConnection    compatibility for firefox and chrome x000D              var pc   new myPeerConnection   iceServers         x000D                  noop   function         x000D                  localIPs       x000D                  ipRegex      0-9  1 3     0-9  1 3   3   a-f0-9  1 4    a-f0-9  1 4   7   g  x000D                  key  x000D              function ipIterate ip    x000D                  if   localIPs ip   onNewIP ip   x000D                  localIPs ip    true  x000D                x000D              pc createDataChannel        create a bogus data channel x000D              pc createOffer function  sdp    x000D                  sdp sdp split   n   forEach function  line    x000D                      if  line indexOf  candidate    lt  0  return  x000D                      line match ipRegex  forEach ipIterate   x000D                      x000D                  pc setLocalDescription sdp  noop  noop   x000D                 noop      create offer and set local description x000D   x000D              pc onicecandidate   function  ice      listen for candidate events x000D                  if  ice  amp  amp  ice candidate  amp  amp  ice candidate candidate  amp  amp  ice candidate candidate match ipRegex     x000D                      ice candidate candidate match ipRegex  forEach ipIterate   x000D                    x000D                  resolve  FindIPsDone    x000D                  return  x000D                 x000D            x000D          catch  ex    x000D              reject Error ex    x000D            x000D            New Promise              x000D      return promise  x000D     x000D   x000D    This is the callback that gets run for each IP address found x000D  function foundNewIP ip    x000D      if  typeof window ipAddress      undefined   x000D        x000D          window ipAddress   ip  x000D        x000D      else x000D        x000D          window ipAddress      -     ip  x000D        x000D    x000D   x000D    This is How to use the Waitable findIP function  and react to the x000D    results arriving x000D  var ipWaitObject   findIP foundNewIP             Puts found IP s  in window ipAddress x000D  ipWaitObject then  x000D      function  result    x000D          alert   IP s  Found   Result       result       You can use them now      window ipAddress  x000D         x000D      function  err    x000D          alert   IP s  NOT Found   FAILED       err  x000D        x000D     x000D   x000D   x000D    x000D   x000D      x000D   lt h1 gt Demo  Waitable  Client IP Retrieval using WebRTC  lt  h1 gt  x000D   x000D   x000D

I would say Chad and Malta has great answer  However  theirs are complicated  So I suggest this code that I found from ads by country plugin   lt script gt   lt script language  javascript  src  http   j maxmind com app geoip js  gt  lt  script gt   lt script language  javascript  gt  mmjsCountryCode   geoip country code    mmjsCountryName   geoip country name      lt  script gt    No ajax  Just plain javascripts   D  If you go to http   j maxmind com app geoip js you will see that it contains  function geoip country code     return  ID     function geoip country name     return  Indonesia     function geoip city             return  Jakarta     function geoip region           return  04     function geoip region name      return  Jakarta Raya     function geoip latitude         return  -6 1744     function geoip longitude        return  106 8294     function geoip postal code      return       function geoip area code        return       function geoip metro code       return         It doesn t really answer the question yet because  http   j maxmind com app geoip js doesn t contain the IP  although I bet it uses the IP to get the country    But it s so easy to make a PhP script that pop something like  function visitorsIP       return  123 123 123 123       Make that  Put on http   yourdomain com yourip php   Then do    lt script language  javascript  src  http   yourdomain com yourip php  gt  lt  script gt    The question specifically mention NOT to use third party script  There is no other way  Javascript cannot know your IP  But other servers that  can be accessed through javascript can which work just as well with no issue

Well  I am digressing from the question  but I had a similar need today and though I couldn t find the ID from the client using Javascript  I did the following   On the server side  -   lt div style  display none visibility hidden  id  uip  gt  lt    Request UserHostAddress   gt  lt  div gt    Using Javascript  var ip    get  uip   innerHTML    I am using ASP Net Ajax  but you can use getElementById instead of  get     What s happening is  I ve got a hidden div element on the page with the user s IP rendered from the server  Than in Javascript I just load that value   This might be helpful to some people with a similar requirement like yours  like me while I hadn t figure this out    Cheers

You can do an ajax call to hostip info or a similar service     function myIP         if  window XMLHttpRequest  xmlhttp   new XMLHttpRequest        else xmlhttp   new ActiveXObject  Microsoft XMLHTTP         xmlhttp open  GET   http   api hostip info get html php  false       xmlhttp send         hostipInfo   xmlhttp responseText split   n         for  i 0  hostipInfo length  gt   i  i              ipAddress   hostipInfo i  split               if   ipAddress 0      IP    return ipAddress 1              return false      As a bonus  geolocalisation information is returned in the same call

Get your IP with jQuery  you can get your public IP address with one line of JS  There is a free service that offers this for you and a get request is all that you need to do        get  http   jsonip com    function r   console log r ip         For the above snippet to work  your browser will have to support CORS  cross-origin request sharing   Otherwise a security exception would be thrown  In older browsers  you can use this version  which uses a JSON-P request        getJSON  http   jsonip com  callback     function r   console log r ip

Well  I am digressing from the question  but I had a similar need today and though I couldn t find the ID from the client using Javascript  I did the following   On the server side  -   lt div style  display none visibility hidden  id  uip  gt  lt    Request UserHostAddress   gt  lt  div gt    Using Javascript  var ip    get  uip   innerHTML    I am using ASP Net Ajax  but you can use getElementById instead of  get     What s happening is  I ve got a hidden div element on the page with the user s IP rendered from the server  Than in Javascript I just load that value   This might be helpful to some people with a similar requirement like yours  like me while I hadn t figure this out    Cheers

There isn t really a reliable way to get the client computer s IP address   This goes through some of the possibilities  The code that uses Java will break if the user has multiple interfaces   http   nanoagent blogspot com 2006 09 how-to-find-evaluate-remoteaddrclients html  From looking at the other answers here it sounds like you may want to get the client s public IP address  which is probably the address of the router they re using to connect to the internet  A lot of the other answers here talk about that  I would recommend creating and hosting your own server side page for receiving the request and responding with the IP address instead of depending on someone else s service that may or may not continue to work

Most of the answers here  work around  the need for server-side code by    Hitting someone else s server  Which is a totally valid technique  unless you actually do need to get the IP address without hitting a server    Traditionally this wasn t possible without some sort of a plugin  and even then  you d likely get the wrong IP address if you were behind a NAT router   but with the advent of WebRTC it is actually possible to do this    If you re targeting browsers that support WebRTC  currently  Firefox  Chrome and Opera     Please read mido s answer for details on how you can retrieve useful client IP addresses using WebRTC

All the above answers have a server part  not pure client part  This should be provided by the web browser  At present  no web browser support this   However  with this addon for firefox  https   addons mozilla org en-US firefox addon ip-address  You will have to ask your users to install this addon   it s good from me  a 3rd party    you can test whether the user has installed it   var installed window IP   undefined    you can get it with javascript  if it is installed  then     var ip IP getClient        var IPclient ip IP        while ip url is the url  ip IP getServer    var IPserver ip IP  var portServer ip port    while ip url is the url    or you can use IP getBoth      more information here  http   www jackiszhp info tech addon IP html

UPDATE 2021  As shown recently by a new Github repository  webrtc-ip  you can now leak a user s public IP address using WebRTC  Sadly  this leak does not work for private IPs  due to the gradual shift to mDNS  at least for WebRTC   completely explained here  However  here s a working demo   x000D   x000D  getIPs   then res   gt  document write res join   n     x000D   lt script src  https   cdn jsdelivr net gh joeymalvinni webrtc-ip dist bundle dev js  gt  lt  script gt  x000D   x000D   x000D   The compiled source code for this repository can be found here       Previously  Final Update This solution would not longer work because browsers are fixing webrtc leak  for more info on that read this other question  RTCIceCandidate no longer returning IP  Update  I always wanted to make a min  uglified version of the code  so here is an ES6 Promise code   x000D   x000D  var findIP   new Promise r  gt  var w window a new  w RTCPeerConnection  w mozRTCPeerConnection  w webkitRTCPeerConnection   iceServers      b     gt    a createDataChannel     a createOffer c  gt a setLocalDescription c b b  b  a onicecandidate c  gt  try c candidate candidate match    0-9  1 3     0-9  1 3   3   a-f0-9  1 4    a-f0-9  1 4   7   g  forEach r  catch e          Usage example   findIP then ip   gt  document write  your ip     ip   catch e   gt  console error e   x000D   x000D   x000D   Note  This new minified code would return only single IP if you want all the IPs of the user  which might be more depending on his network   use the original code     thanks to WebRTC  it is very easy to get local IP in WebRTC supported browsers  at least for now   I have modified the source code  reduced the lines  not making any stun requests since you only want Local IP  not the Public IP  the below code works in latest Firefox and Chrome  just run the snippet and check for yourself   x000D   x000D  function findIP onNewIP        onNewIp - your listener function for new IPs   var myPeerConnection   window RTCPeerConnection    window mozRTCPeerConnection    window webkitRTCPeerConnection    compatibility for firefox and chrome   var pc   new myPeerConnection  iceServers            noop   function           localIPs           ipRegex      0-9  1 3     0-9  1 3   3   a-f0-9  1 4    a-f0-9  1 4   7   g      key     function ipIterate ip        if   localIPs ip   onNewIP ip       localIPs ip    true        pc createDataChannel        create a bogus data channel   pc createOffer function sdp        sdp sdp split   n   forEach function line          if  line indexOf  candidate    lt  0  return        line match ipRegex  forEach ipIterate               pc setLocalDescription sdp  noop  noop        noop      create offer and set local description   pc onicecandidate   function ice      listen for candidate events     if   ice     ice candidate     ice candidate candidate     ice candidate candidate match ipRegex   return      ice candidate candidate match ipRegex  forEach ipIterate             var ul   document createElement  ul    ul textContent    Your IPs are    document body appendChild ul    function addIP ip      console log  got ip     ip     var li   document createElement  li      li textContent   ip    ul appendChild li      findIP addIP   x000D   lt h1 gt  Demo retrieving Client IP using WebRTC  lt  h1 gt  x000D   x000D   x000D   what is happening here is  we are creating a dummy peer connection  and for the remote peer to contact us  we generally exchange ice candidates with each other  And reading the ice candidates  from local session description and onIceCandidateEvent  we can tell the IP of the user  where I took code from -- gt  Source

It can t be done with Javascript alone  unless the clients have a browser plugin as described above   It can t be done with Flash on the client either  But it can be done on the client using a Java applet  and javascript can talk to that   although it will prompt for full permissions  e g  See http   www findmyrouter net

User · Answer

You could do this entirely client side and mostly in JavaScript by using a Flash object that the js can call  Flash can access the IP address of the local machine which might not be very useful

Well  I am digressing from the question  but I had a similar need today and though I couldn t find the ID from the client using Javascript  I did the following   On the server side  -   lt div style  display none visibility hidden  id  uip  gt  lt    Request UserHostAddress   gt  lt  div gt    Using Javascript  var ip    get  uip   innerHTML    I am using ASP Net Ajax  but you can use getElementById instead of  get     What s happening is  I ve got a hidden div element on the page with the user s IP rendered from the server  Than in Javascript I just load that value   This might be helpful to some people with a similar requirement like yours  like me while I hadn t figure this out    Cheers

One problem with some of the other services I ve seen here is that they either do not support IPv6  or they act unpredictably in the presence of IPv6   Because I needed this capability myself in a dual stack environment  I put together my own IP address service  which you can find at http   myip addr space    There s also a quick reference at  help   To use it with jQuery  use the  ip endpoint  You will get back plain text containing the IP address  depending on the subdomain you use     get  http   myip addr space ip   returns either IPv6 or IPv4  depending on what is available to the system   JSFiddle     get  http   ipv4 myip addr space ip   always returns IPv4  or fails if no IPv4      get  http   ipv6 myip addr space ip   always returns IPv6  or fails if no IPv6

One problem with some of the other services I ve seen here is that they either do not support IPv6  or they act unpredictably in the presence of IPv6   Because I needed this capability myself in a dual stack environment  I put together my own IP address service  which you can find at http   myip addr space    There s also a quick reference at  help   To use it with jQuery  use the  ip endpoint  You will get back plain text containing the IP address  depending on the subdomain you use     get  http   myip addr space ip   returns either IPv6 or IPv4  depending on what is available to the system   JSFiddle     get  http   ipv4 myip addr space ip   always returns IPv4  or fails if no IPv4      get  http   ipv6 myip addr space ip   always returns IPv6  or fails if no IPv6
