I asked about this a while back - see IPv6 Name Resolution.

The solution for me was to use Socket::GetAddrInfo with the following:

use if $] <  5.014, "Socket" => qw(inet_ntoa unpack_sockaddr_in IPPROT
+O_TCP AF_INET AF_UNSPEC);
use if $] <  5.014, "Socket6";
use if $] <  5.014, "Socket::GetAddrInfo" => qw(getaddrinfo getnameinf
+o);
use if $] >= 5.014, "Socket" => qw(:addrinfo inet_ntoa inet_ntop unpac
+k_sockaddr_in unpack_sockaddr_in6 IPPROTO_TCP AF_INET AF_UNSPEC);

If you want your program to run on both Windows and Linux, good luck. Socket does have IPv6 support on Linux. With Windows, it appears the headers and libraries supplied with Strawberry's C compiler don't have the IPv6 routines (get*info); however, they ARE available on Windows and I've compiled C programs that use them. I'm guessing Strawberry Perl gcc compiler (headers and libraries) need to be updated and the Socket module recompiled as Windows 7 will support it, but not in the current Strawberry distribution (I'm running 5.12.3, but have also tested with 5.14).

UPDATE: See UPDATE section in Re^2: ipv6 support on windows.
