libsocket-getaddrinfo-perl 0.20-2build2 (i386 binary) in ubuntu quantal

 Socket::GetAddrInfo provides a Perl implementation of the getaddrinfo and
 getnameinfo functions as described in RFC 2553. These functions are useful for
 converting between a pair of host name/service name and socket addresses, or
 vice versa.
 .
 This module uses underlying C code to do most of the work if possible, but can
 also fall back on some mostly-compatible emulation code written in Perl. This
 means that this module is a fairly portable implementation of these functions.
