Getting the location from an IP address

Question

I want to retrieve information like the city  state  and country of a visitor from their IP address  so that I can customize my web page according to their location  Is there a good and reliable way to do this in PHP  I am using JavaScript for client-side scripting  PHP for server-side scripting  and MySQL for the database

There 2 broad approaches to perform IP geolocation: one is to download a dataset, host it on your infrastructure and maintain it up-to-date. This requires time and effort, especially if you need to support a high number of requests. Another solution is to use an existing API service that manages all the work for you and more.

There exist many API Geolocation services: Maxmind, Ip2location, Ipstack, IpInfo, etc. Recently, the company I work for has switched to Ipregistry (https://ipregistry.co) and I was involved in the decision and implementation process. Here are some elements you should consider while looking for an IP geolocation API:

Is the service accurate? are they using a single source of information?
Can they really handle your load?
Do they provide consistent and fast response times Worldwide (except if your users are country specific)?
What's their pricing model?

Here is an example to get IP geolocation information (but also threat and user agent data using one call):

$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("https://api.ipregistry.co/{$ip}?key=tryout"));
echo $details->location;

Note: I am not here to promote Ipregistry and say it's the best but I spent a long time analyzing existing solutions and their solution is really promising.

In case anyone stumbles upon this thread  here s another solution  At timezoneapi io you can request an IP address and get several objects in return  I ve created the service   It was created because I needed to know which timezone my users were in  where in the world and what time it currently is   In PHP - returns location  timezone and date time      Get IP address  ip address   getenv  HTTP CLIENT IP      getenv  HTTP X FORWARDED FOR      getenv  HTTP X FORWARDED      getenv  HTTP FORWARDED FOR      getenv  HTTP FORWARDED      getenv  REMOTE ADDR        Get JSON object  jsondata   file get contents  http   timezoneapi io api ip       ip address       Decode  data   json decode  jsondata  true       Request OK  if  data  meta    code       200            Example  Get the city parameter     echo  City       data  data    city       lt br gt            Example  Get the users time     echo  Time       data  data    datetime    date time txt       lt br gt         Using jQuery      Get JSON object   getJSON  https   timezoneapi io api ip   function data           Request OK      if data meta code     200                Log         console log data               Example  Get the city parameter         var city   data data city          alert city               Example  Get the users time         var time   data data datetime date time txt          alert time

Thought I d post as nobody seems to have given info on this particular API  but its returning exactly what I m after and you can get it to return in multiple formats  json  xml and csv     location   file get contents  http   freegeoip net json     SERVER  REMOTE ADDR      print r  location     This will give you all of the things you could possibly want            ip    77 99 179 98          country code    GB          country name    United Kingdom          region code    H9          region name    London  City of          city    London          zipcode              latitude   51 5142         longitude   -0 0931         metro code              areacode

You could download a free GeoIP database and lookup the IP address locally  or you could use a third party service and perform a remote lookup  This is the simpler option  as it requires no setup  but it does introduce additional latency    One third party service you could use is mine  http   ipinfo io  They provide hostname  geolocation  network owner and additional information  eg     curl ipinfo io 8 8 8 8      ip    8 8 8 8      hostname    google-public-dns-a google com      loc    37 385999999999996 -122 0838      org    AS15169 Google Inc       city    Mountain View      region    CA      country    US      phone   650     Here s a PHP example    ip     SERVER  REMOTE ADDR     details   json decode file get contents  http   ipinfo io   ip  json     echo  details- gt city     - gt   Mountain View    You can also use it client-side  Here s a simple jQuery example    x000D   x000D    get  https   ipinfo io json   function  response    x000D          ip   html  IP      response ip   x000D          address   html  Location      response city          response region   x000D          details   html JSON stringify response  null  4    x000D      jsonp    x000D   lt script src  https   ajax googleapis com ajax libs jquery 1 11 1 jquery min js  gt  lt  script gt  x000D   lt h3 gt Client side IP geolocation using  lt a href  http   ipinfo io  gt ipinfo io lt  a gt  lt  h3 gt  x000D   x000D   lt hr  gt  x000D   lt div id  ip  gt  lt  div gt  x000D   lt div id  address  gt  lt  div gt  x000D   lt hr  gt Full response   lt pre id  details  gt  lt  pre gt  x000D   x000D   x000D

This question is protected  which I understand  However  I do not see an answer here  what I see is a lot of people showing what they came up with from having the same question   There are currently five Regional Internet Registries with varying degrees of functionality that serve as the first point of contact with regard to IP ownership  The process is in flux  which is why the various services here work sometimes and don t at other times   Who Is is  obviously  an ancient TCP protocol  however -- the way it worked originally was by connection to port 43  which makes it problematic getting it routed through leased connections  through firewalls   etc   At this moment -- most Who Is is done via RESTful HTTP and ARIN  RIPE and APNIC have RESTful services that work  LACNIC s returns a 503 and AfriNIC apparently has no such API   All have online services  however    That will get you -- the address of the IP s registered owner  but -- not your client s location -- you must get that from them and also -- you have to ask for it  Also  proxies are the least of your worries when validating the IP that you think is the originator   People do not appreciate the notion that they are being tracked  so -- my thoughts are -- get it from your client directly and with their permission and expect a lot to balk at the notion

I like the free GeoLite City from Maxmind which works for most applications and from which you can upgrade to a paying version if it s not precise enough  There is a PHP API included  as well as for other languages  And if you are running Lighttpd as a webserver  you can even use a module to get the information in the SERVER variable for every visitor if that s what you need   I should add there is also a free Geolite Country  which would be faster if you don t need to pinpoint the city the IP is from  and Geolite ASN  if you want to know who owns the IP  and that finally all these are downloadable on your own server  are updated every month and are pretty quick to lookup with the provided APIs as they state  thousands of lookups per second

This question is protected  which I understand  However  I do not see an answer here  what I see is a lot of people showing what they came up with from having the same question   There are currently five Regional Internet Registries with varying degrees of functionality that serve as the first point of contact with regard to IP ownership  The process is in flux  which is why the various services here work sometimes and don t at other times   Who Is is  obviously  an ancient TCP protocol  however -- the way it worked originally was by connection to port 43  which makes it problematic getting it routed through leased connections  through firewalls   etc   At this moment -- most Who Is is done via RESTful HTTP and ARIN  RIPE and APNIC have RESTful services that work  LACNIC s returns a 503 and AfriNIC apparently has no such API   All have online services  however    That will get you -- the address of the IP s registered owner  but -- not your client s location -- you must get that from them and also -- you have to ask for it  Also  proxies are the least of your worries when validating the IP that you think is the originator   People do not appreciate the notion that they are being tracked  so -- my thoughts are -- get it from your client directly and with their permission and expect a lot to balk at the notion

There 2 broad approaches to perform IP geolocation: one is to download a dataset, host it on your infrastructure and maintain it up-to-date. This requires time and effort, especially if you need to support a high number of requests. Another solution is to use an existing API service that manages all the work for you and more.

There exist many API Geolocation services: Maxmind, Ip2location, Ipstack, IpInfo, etc. Recently, the company I work for has switched to Ipregistry (https://ipregistry.co) and I was involved in the decision and implementation process. Here are some elements you should consider while looking for an IP geolocation API:

Is the service accurate? are they using a single source of information?
Can they really handle your load?
Do they provide consistent and fast response times Worldwide (except if your users are country specific)?
What's their pricing model?

Here is an example to get IP geolocation information (but also threat and user agent data using one call):

$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("https://api.ipregistry.co/{$ip}?key=tryout"));
echo $details->location;

Note: I am not here to promote Ipregistry and say it's the best but I spent a long time analyzing existing solutions and their solution is really promising.

If you need to get location from an IP address you can use reliable geo ip service  you can get more detail here  It supports IPv6   As a bonus it allows to check whether ip address is a tor node  public proxy or spammer    You can use javascript or php as below   Javascript Code     document  ready function                  btnGetIpDetail   click function                  if      txtIP   val                            alert  IP address is reqired                    return false                              getJSON  http   ip-api io json         txtIP   val                     function  result                         alert  City Name      result city                       console log result                                              Php Code    result   json decode file get contents  http   ip-api io json 64 30 228 118     var dump  result     Output      ip    64 30 228 118    country code    US    country name    United States    region code    FL    region name    Florida    city    Fort Lauderdale    zip code    33309    time zone    America New York    latitude   26 1882   longitude   -80 1711   metro code   528   suspicious factors      is proxy   false   is tor node   false   is spam   false   is suspicious   false

The service in Ben Dowling s response has changed  so it s now simpler  To find the location  simply do      no need to pass ip any longer  ipinfo grabs the ip of the person requesting  details   json decode file get contents  http   ipinfo io      echo  details- gt city     city   The coordinates return in a single string like  31 -80   so from there you just    coordinates   explode       details- gt loc      - gt   31 -89  becomes 31   -80  echo  coordinates 0      latitude echo  coordinates 1      longitude

The service in Ben Dowling s response has changed  so it s now simpler  To find the location  simply do      no need to pass ip any longer  ipinfo grabs the ip of the person requesting  details   json decode file get contents  http   ipinfo io      echo  details- gt city     city   The coordinates return in a single string like  31 -80   so from there you just    coordinates   explode       details- gt loc      - gt   31 -89  becomes 31   -80  echo  coordinates 0      latitude echo  coordinates 1      longitude

You could download a free GeoIP database and lookup the IP address locally  or you could use a third party service and perform a remote lookup  This is the simpler option  as it requires no setup  but it does introduce additional latency    One third party service you could use is mine  http   ipinfo io  They provide hostname  geolocation  network owner and additional information  eg     curl ipinfo io 8 8 8 8      ip    8 8 8 8      hostname    google-public-dns-a google com      loc    37 385999999999996 -122 0838      org    AS15169 Google Inc       city    Mountain View      region    CA      country    US      phone   650     Here s a PHP example    ip     SERVER  REMOTE ADDR     details   json decode file get contents  http   ipinfo io   ip  json     echo  details- gt city     - gt   Mountain View    You can also use it client-side  Here s a simple jQuery example    x000D   x000D    get  https   ipinfo io json   function  response    x000D          ip   html  IP      response ip   x000D          address   html  Location      response city          response region   x000D          details   html JSON stringify response  null  4    x000D      jsonp    x000D   lt script src  https   ajax googleapis com ajax libs jquery 1 11 1 jquery min js  gt  lt  script gt  x000D   lt h3 gt Client side IP geolocation using  lt a href  http   ipinfo io  gt ipinfo io lt  a gt  lt  h3 gt  x000D   x000D   lt hr  gt  x000D   lt div id  ip  gt  lt  div gt  x000D   lt div id  address  gt  lt  div gt  x000D   lt hr  gt Full response   lt pre id  details  gt  lt  pre gt  x000D   x000D   x000D
