Hi Todd,
IO::Socket::IP is the only established way to do IPv6 in Perl in a comfortable
way (i.e. using the IO::Socket::* modules). And If I understand the code of
IO::Socket correctly it does not provide any IPv6 functionality by itself but refers
to IO::Socket::IP for this, same as it refers to IO::Socket::INET for IPv4 (see
the register_domain functionality). Thus it would not help to base the code on
IO::Socket instead of IO::Socket::IP.
If you don't need IPv6 you can load IO::Socket::SSL with 'inet4'. In this case
it will be based on IO::Socket::INET instead of IO::Socket::IP.
Apart from that I suggest that you contact the author of IO::Socket::IP to
see if it would be possible to work without the POSIX module. But you probably
would need the right arguments instead of just pointing to your policy of
avoiding anything tainted by POSIX. Based on my experience the author is
open to useful patches.

Steffen
