get your public IP with my little doo-hickey here

[inkedmn]

whipped this up while setting up my mom's machine. she's got a dsl router with 192.168 addressing internally. but i'd like to be able to access her stuff over the internet, so i'd need her public ip. wrote this little script to get it. this should work from within any internal network to get the IP from your router/gateway/etc...


import urllib, re

def getIp():
conn = urllib.urlopen("http://www.whatismyip.com")
html = conn.read()
textonly = re.sub('<.*?>', '', html)
lines = textonly.strip().split('\n')
return lines[0].strip().split(' ')[3]

print "Your public IP is: " + getIp()


btw, had this running in about 3 minutes...
~praise python :)

k... fixed it by putting

import re


on a different line... my computer is weird :rolleyes:

run a traceroute google.com and grab the second IP ;)

that would work as well...

but parsing a basic html page was easier to code than parsing the output of a tracert (at the time).

And more secure and portable. Traceroute isn't available on all systems.

not to mention the fact that, for somebody like me (who has a dialup ;)), waiting for a traceroute (which, on windows machines, takes as many hops as necessary to get to the destination IP up to 30) could take quite awhile to finish.

then, there's parsing the output. i think my way is much easier.

IMHO, of course :)
