import os,urllib2,re


def getIpAddr():
"""
Function for parsing external ip adress by pinging dyndns.com
"""
External_IP=urllib2.urlopen('http://checkip.dyndns.com/').read()
m = re.search(r"(([0-9]+\.){3}[0-9]+)", External_IP)
my_IP= m.group(1)
return my_IP




print('Current Ip from DynDns : %s ') % getIpAddr()



this gets you your ip address

Hi,

It's not my ip address that I want to discover... I want to discover
my default dns server ip address.
This ip is stored in an operative system basis.

Dos anyone know how to get it ?

You asked for a cross-platform solution; there probably isn't one.

The code below works on Unix and MacOS X.
If you can find code that works on Windows, you can cobble together
somthing that will work on most platforms.

dns_ips = []

for line in file('/etc/resolv.conf', 'r'):
columns = line.split()
if columns[0] == 'nameserver':
dns_ips.extend(columns[1:])

print dns_ips


Hope this help,
