Do you really need any kind of additional processing ?
The basic sort algorithm is smart enough to do this by itself,
>>> l=['192.168.1.1','172.18.13.2','192.168.3.2','172.19.2.1']
>>>l.sort()
>>>l
['172.18.13.2', '172.19.2.1', '192.168.1.1', '192.168.3.2']
or use sorted(...) if you don't want to modify in place...
Here is an even closer example to demo this...
>>> l=['192.168.12.21','192.168.12.15','192.168.11.10','192.168.10.5','192.168.15.1','192.167.10.1']
>>> sorted(l)
['192.167.10.1', '192.168.10.5', '192.168.11.10', '192.168.12.15',
'192.168.12.21', '192.168.15.1']
