To the extent that Clay is having issues, it's because ipaddr.py is poorly
documented, has potentially confusing comments, and he became confused.
Lesser issues are that ipaddr.py doesn't work the way he wants and that ip
addressing is inherently subtle.
Looking at the code in detail shows that ipaddr.IP/IPv4/IPv6 objects always
represent *networks*. He wants one particular address out of that network,
and that requires using __getitem__ or using IP.ip_ext. Neither is
particularly intuitive.
>>> import ipaddr
>>> ip = ipaddr.IPv4('10.33.11.17')
>>> ip
IPv4('10.33.11.17/32')
>>> ip[0]
'10.33.11.17'
>>> ip.ip_ext
'10.33.11.17'
>>>
This feels much more like poor documentation than wide-ranging conceptual
flaws.
I could put this in the tracker, but I'm not sure if that's appropriate.
