No chance at the moment to test/look through the code, so please excuse any
obvious ones, I'm basing my comments on the PEP.
Some elaboration on handling ipv4 mapped addresses would be nice, e.g.
::ffff:c000:280 and/or ::ffff:192.168.0.128
Some IPv6 examples would also help the PEP I think. Especially on how 0
compression is handled in addresses.
Maybe show ipv4 examples on non-class boundaries, e.g. /23 instead of /24,
so people are more convinced it handles CIDR properly.
Clarification on whether this library will support converting a sequence of
networks into another sequence where the networks which comprise consecutive
netblocks will be collapsed in a new entry. E.g. 2 /24s that are neighbours
will be represented as one /23.
I realise some might be answered by the last paragraph of your PEP, but it
would be nice to know what you consider essential and what not.
