New issue 48 by thelonelywolf: network recognition
http://code.google.com/p/netaddr/issues/detail?id=48
Hi
before all thanks for your commit #337 :P
Sorry for the question, i've tried to search within documentation without
success, however, let's say we have 2 (or more) different ip address:
192.168.0.1 and 192.168.1.6
Is there any way/method that return something like: "this 2 address belongs
to two different networks"?
Thanks for your attention :)

you could find the supernets of each and the find the union of those sets.
something like
In [12]: addr1 = netaddr.IPNetwork('192.168.0.1')
In [13]: addr2 = netaddr.IPNetwork('192.168.1.6')
In [14]: set.union(set(addr1.supernet()), set(addr2.supernet()))
Out[15]: set([IPNetwork('192.128.0.0/9'), IPNetwork('192.0.0.0/6'),
IPNetwork('192.128.0.0/10'), IPNetwork('192.0.0.0/5'),
IPNetwork('192.168.0.0/16'), IPNetwork('192.168.1.0/29'),
IPNetwork('192.168.0.0/26'), IPNetwork('192.168.0.0/22'),

ah, intersection was what I was thinking of.
(sorted, for cleanliness)
In [18]: sorted(set.intersection(set(addr1.supernet()),
set(adr2.supernet())))
Out[18]:
[IPNetwork('0.0.0.0/0'),
IPNetwork('128.0.0.0/1'),
IPNetwork('192.0.0.0/2'),
IPNetwork('192.0.0.0/3'),
IPNetwork('192.0.0.0/4'),
IPNetwork('192.0.0.0/5'),
IPNetwork('192.0.0.0/6'),
IPNetwork('192.0.0.0/7'),
IPNetwork('192.0.0.0/8'),
