The code isn't very robust if anything happens retrieving the IP-website 
- if for some reason the connection is broken, it won't catch any 
ensuing IO-exception.

Also your way of extracing the IP is rather awkward, a simple re (often 
not the right tool, but here certainl yes) would help:

 >>> m = re.search(r"(([0-9]+\.){3}[0-9]+)", body)
 >>> m.group(1)
'85.177.92.101'
 >>>
