Getting a machine s external IP address with Python

Question

Looking for a better way to get a machines current external IP      Below works  but would rather not rely on an outside site to gather the information     I am restricted to using standard Python 2 5 1 libraries bundled with Mac OS X 10 5 x  import os import urllib2  def check in         fqn   os uname   1      ext ip   urllib2 urlopen  http   whatismyip org   read       print   Asset   s     fqn   Checking in from IP    s     ext ip

If you don t want to use external services  IP websites  etc   You can use the UPnP Protocol   Do to that we use a simple UPnP client library  https   github com flyte upnpclient   Install      pip install upnpclient   Simple Code   import upnpclient  devices   upnpclient discover    if len devices   gt  0       externalIP   devices 0  WANIPConn1 GetExternalIPAddress       print externalIP  else      print  No Connected network interface detected     Full Code  to get more information as mentioned in the github readme   In  1   import upnpclient  In  2   devices   upnpclient discover    In  3   devices Out 3      lt Device  OpenWRT router  gt     lt Device  Harmony Hub  gt     lt Device  walternate  root  gt    In  4   d   devices 0   In  5   d WANIPConn1 GetStatusInfo   Out 5      NewConnectionStatus    Connected     NewLastConnectionError    ERROR NONE     NewUptime   14851479   In  6   d WANIPConn1 GetNATRSIPStatus   Out 6     NewNATEnabled   True   NewRSIPAvailable   False   In  7   d WANIPConn1 GetExternalIPAddress   Out 7     NewExternalIPAddress    123 123 123 123

If you are behind a router which obtains the external IP  I m afraid you have no other option but to use external service like you do  If the router itself has some query interface  you can use it  but the solution will be very environment-specific and unreliable

Python3  using nothing else but the standard library As mentioned before  one can use an external service like https   ident me in order to discover the external IP address of your router  Here is how it is done with python3  using nothing else but the standard library  import urllib request  external ip   urllib request urlopen  https   ident me   read   decode  utf8    print external ip

If you are not interested in hitting any url to get public ip  I think following code can help you to get public ip using python of your machine  import os externalIP    os popen  ifconfig   grep  inet    cut -d  -f2   awk   print  2     sed -n 3p   readline   print externalIP   sed -n 3p line varies as per the network you are using for connecting device   I was facing same issue  I was needed public ip of iot device which is hitting my server  but public ip is totally different in ifconfig command and ip i am getting in server from request object  after this I am adding extra param into my request to send ip of device to my server    hope this is helpful

If you think and external source is too unreliable  you could pool a few different services  For most ip lookup pages they require you to scrape html  but a few of them that have created lean pages for scripts like yours - also so they can reduce the hits on their sites    automation whatismyip com n09230945 asp  Update  whatismyip has taken this service down  whatismyip org

You should use the UPnP protocol to query your router for this information  Most importantly  this does not rely on an external service  which all the other answers to this question seem to suggest   There s a Python library called miniupnp which can do this  see e g  miniupnpc testupnpigd py   pip install miniupnpc   Based on their example you should be able to do something like this   import miniupnpc  u   miniupnpc UPnP   u discoverdelay   200 u discover   u selectigd   print  external ip address      format u externalipaddress

There are a few other ways that do not rely on Python checking an external web site  however the OS can   Your primary issue here  is that even if you were not using Python  if you were using the command line  there are no  built-in  commands that can just simply tell you the external  WAN  IP   Commands such as  ip addr show  and  ifconfig -a  show you the server s IP address s within the network   Only the router actually holds the external IP   However  there are ways to find the external IP address  WAN IP  from the command line     These examples are   http   ipecho net plain   echo curl ipinfo io ip dig  short myip opendns com  resolver1 opendns com dig TXT  short o-o myaddr l google com  ns1 google com   Therefore  the python code would be   import os ip   os popen  wget -qO- http   ipecho net plain   echo   readlines -1  0  strip   print ip   OR  import os iN  out  err   os popen3  curl ipinfo io ip   iN close     err close   ip   out read   strip   print ip   OR  import os ip   os popen  dig  short myip opendns com  resolver1 opendns com   readlines -1  0  strip   print ip   Or  plug any other of the examples above  into a command like os popen  os popen2  os popen3  or os system

I tried most of the other answers on this question here and came to find that most of the services used were defunct except one   Here is a script that should do the trick and download only a minimal amount of information      usr bin env python  import urllib import re  def get external ip        site   urllib urlopen  http   checkip dyndns org    read       grab   re findall    0-9     0-9     0-9     0-9      site      address   grab 0      return address  if   name         main       print  get external ip

The most simple  non python  working solution I can think of is  wget -q -O- icanhazip com   I d like to add a very short Python3 solution which makes use of the JSON API of http   hostip info   from urllib request import urlopen import json url    http   api hostip info get json php  info   json loads urlopen url  read   decode  utf-8    print info  ip      You can of course add some error checking  a timeout condition and some convenience      usr bin env python3 from urllib request import urlopen from urllib error import URLError import json  try      url    http   api hostip info get json php      info   json loads urlopen url  timeout   15  read   decode  utf-8        print info  ip    except URLError as e      print e reason  end        e g   timed out      print   are you connected to the internet     except KeyboardInterrupt      pass

If you re just writing for yourself and not for a generalized application  you might be able to find the address on the setup page for your router and then scrape it from that page s html  This worked fine for me with my SMC router  One read and one simple RE search and I ve found it   My particular interest in doing this was to let me know my home IP address when I was away from home  so I could get back in via VNC  A few more lines of Python stores the address in Dropbox for outside access  and even emails me if it sees a change  I ve scheduled it to happen on boot and once an hour thereafter

If the machine is being a firewall then your solution is a very sensible one  the alternative being able to query the firewall which ends-up being very dependent on the type of firewall  if at all possible
