Why are you re-defining sockaddr_in and in_addr? the definitions are already in the header files. Besides that there is no need for the structures. The only structure you need is hostent.
The way your handling SA is not correct. You define it as a pointer but never allocate memory for it. You should also be using the -> operator instead of . when accessing structure members.
Why are you calling getnameinfo()? You should call gethostbyaddr().
I know what your trying to do but you are way off. The majority of the code does not apply to what your doing.

socket_getnameinfo
SOCKET_GETNAMEINFO(1p) User Contributed Perl Documentation SOCKET_GETNAMEINFO(1p)NAME
"socket_getnameinfo" - command-line tool to "getnameinfo(3)" resolver
SYNOPSIS
socket_getnameinfo [options...] address port
DESCRIPTION
This tool provides a convenient command-line wrapper around the getnameinfo(3) resolver function. It will perform a single reverse lookup
to convert an address and port number into its host and service names. This is mainly useful when debugging names resolution problems,
because it allows inspection of the getnameinfo(3) behaviour itself, outside of any real program that is trying to use it.
OPTIONS --address, -A ADDR
Numerical form of address to look up. If not supplied, will use the first positional argument.
--port, -P PORT
Port number to look up. If not supplied, will use the second positional argument.
--dgram Sets the "NI_DGRAM" flag; looks up a "SOCK_DGRAM" (udp) port allocation rather than "SOCK_STREAM" (tcp).
--help Display a help summary and exit
NOTE
Upstream this script is known as "getnameinfo", but was renamed on Debian.
