Re:GitHub is preparing for IPv6 support for Github.com

Sounds like the opposite of this bug. GitHub's system represents 0.0.0.0/0 and ::ffff:0.0.0.0/96 as distinct values, when they should be merged/normalized.
I think it's best to treat IPv4-mapped addresses as an implementation detail of the socket API, and not leak them into general purpose code.
Though things get interesting when an external user provides "::ffff:1.2.3.4" as text.
