determining an assigned IP address

[Mike Fletcher]

def getLocalHostIP( remote = ("www.yahoo.com", 80), forceCompute=0):
	'''Get the "public" address of the local machine, i.e.
	that address which is connected to the general internet.
	
	Code by Donn Cave, posted to comp.lang.python'''
	try:
		if not forceCompute:
			return LOCALHOST_PUBLIC_IP
	except NameError:
		pass
	import socket
	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	s.connect( remote )
	ip, localport = s.getsockname()
	s.close()
	global LOCALHOST_PUBLIC_IP
	LOCALHOST_PUBLIC_IP = ip
	return ip

The following Perl code works:

  use Sys::Hostname;
  use Socket;

  $ip=gethostbyname(hostname());
  $theip=inet_ntoa($ip);


It should be relatively straightforward to convert this to Python.
