IIRC, there was recently some IPv6 related activity on p5p. Either some patches were accepted into blead, or some proposals were made.
IPv6 is something where support for has been lacking in Perl5. We'd like to have it, and have it in the core distribution (either in the core, or in the core modules). I'd say, check out the current status in blead, and head over to p5p to find out how you can contribute. (If it's in blead now, it's most likely to be in next version of Perl - which is scheduled to be released in spring 2011).
Remember, it's p5p where changes to [pP]erl happen. Not Perlmonks.
