[Python] Example of getting public IP-address

public_ip.py

"""
Currently there are several options:

ip.42.pl
jsonip.com
httpbin.org
ipify.org
Below are exact ways you can utilize each of the above.
"""

# ip.42.pl

from urllib2 import urlopen
my_ip = urlopen('http://ip.42.pl/raw').read()
This is the first option I have found. It is very convenient for scripts, you don't need JSON parsing here.

# jsonip.com

from json import load
from urllib2 import urlopen

my_ip = load(urlopen('http://jsonip.com'))['ip']
Seemingly the sole purpose of this domain is to return IP address in JSON.

# httpbin.org

from json import load
from urllib2 import urlopen

my_ip = load(urlopen('http://httpbin.org/ip'))['origin']
httpbin.org is service I often recommend to junior developers to use for testing their scripts / applications.

# ipify.org

from json import load
from urllib2 import urlopen

my_ip = load(urlopen('https://api.ipify.org/?format=json'))['ip']
Power of this service results from lack of limits (there is no rate limiting), infrastructure (placed on Heroku, with high availability in mind) and flexibility (works for both IPv4 and IPv6).
