=head1 NAME
Net::INET6Glue::INET_is_INET6 - make L<IO::Socket::INET> behave like
L<IO::Socket::INET6>
=head1 SYNOPSIS
use Net::INET6Glue::INET_is_INET6;
use LWP::Simple;
print get( 'http://[::1]:80' );
print get( 'http://ipv6.google.com' );
=head1 DESCRIPTION
Many modules directly create L<IO::Socket::INET> sockets or have it as a
superclass. Because L<IO::Socket::INET> has no support for IPv6 these modules
don't have it either.
This module tries to make L<IO::Socket::INET> behave like L<IO::Socket::INET6>
by copying the symbol table from L<IO::Socket::INET6> into L<IO::Socket::INET>.
The original symbol table from L<IO::Socket::INET> is still available in
L<IO::Socket::INET4>.
This strategy works for L<Net::SMTP>, L<LWP> and probably a lot of other modules
too, which don't try to depend too much on the innards of L<IO::Socket::INET> or
on the text representation of IP addresses (IPv6 addresses look different than
IPv4 addresses).
