.IX Header "DESCRIPTION"
This module is a wrapper for \fISocket\fR\|(3) and \fISocket6\fR\|(3), and is meant to
be used in lieu of using those packages directly.  Doing so removes any of the
version dependent support issues on Perl and its bundled \fISocket\fR\|(3) where
IPv6 is concerned.
.PP
Starting in Perl 5.12 the beginnings of IPv6 support emerged in the bundled
\&\fISocket\fR\|(3) module, but full IPv6 support didn't arrive until 5.14.  Prior
versions of Perl required the use of the external \fISocket6\fR\|(3) module 
(available on \s-1CPAN\s0).
.PP
With this module IPv6 support, if available, is brought in automatically at
runtime, regardless of where that support is provided.  It also makes a
default export of \fBinet_pton\fR and \fBinet_ntop\fR, something that \fISocket\fR\|(3)
only does on request.
.PP
Finally, this module provides a \fBhas_ipv6\fR function which will return whether
your Perl has full IPv6 support.  Full support is determined by the presence
of \fBsockaddr_in6\fR.
.PP
All of the regular tag sets provided by either \fBSocket\fR modules are supported
by this module.
