One high-level summary I co-wrote:

Long story short: 

  use IO::Socket::IP;

for a fully IPv6-aware replacement of IO::Socket::INET. Pure-perl, no
non-core dependencies on 5.13.x / 5.14. Requires Socket::GetAddrInfo on
earlier perls, which is XS-based.

Once 5.14.0 is out, I'm hoping to suggest placing IO::Socket::IP in core
too, alongside the older ::INET.
