Here is the final code I generated:

sub make_server
{
   my ($ipv6,$localHost,$conn,$protocol,$socket_port,$verbose) = @_;
   my $server;
    
   print "Using protocol = $protocol on $localHost with port = $socket
+_port.\n" if $verbose;
    
   if ($ipv6)
   {
       print "Running IPv6 tests.\n" if $verbose;
       $server = IO::Socket::INET6->new(LocalAddr  => "$localHost:$soc
+ket_port",
                                        Proto      => $protocol,
                                        Reuse      => 1,
                                        Listen     => $conn)
        or die "Couldn't make IPv6 server on port $socket_port: $@\n";
       print "Running IPv6 enabled on port $socket_port.\n" if $verbos
+e;
   }
   else
   {
       print "Running IPv4 tests.\n" if $verbose;
       $server = IO::Socket::INET->new(LocalAddr  => "$localHost:$sock
+et_port",
                                       Proto      => $protocol,
                                       Reuse      => 1,
                                       Listen     => $conn)
        or die "Can't make $protocol server on port $socket_port: $@\n
+";
       print "Running on port $socket_port.\n" if $verbose;
   }
   return($server);
}

A little about this code....it's made to use the $protocol flag to handle some test cases for TCP and UDP, the Server starts up and handles a Client that connects using similar code to start up with the same conditions. What I was trying to handle was not only IPv4 but IPv6, plus conditions for TCP and UDP so I can just send flags to the creation of the Server or Client and have them generate what I need.

Of course none of this addresses the fact that I also need to make something with Named Pipes for Windows, but that's another story.
