If you want to support both IPv4 and IPv6, you'd use the code in Socket6's Synopsis. (Adjusted for your needs below.)

use strict;
use warnings;

use Socket;
use Socket6;

my @res = getaddrinfo($D{'XXTarget'}, $D{'XXPort'}, AF_UNSPEC, SOCK_ST
+REAM);

my $sock;
my $host;
my $port;

while (@res >= 5) {
   my ($family, $socktype, $proto, $saddr, $canonname) = splice(@res, 
+0, 5);
   ($host, $port) = getnameinfo($saddr, NI_NUMERICHOST | NI_NUMERICSER
+V);

   # log("Trying to connect to $host port port $port...\n");

   socket($sock, $family, $socktype, $proto)
      or next;

   connect($sock, $saddr)
      and last;

   undef $sock;
}

if (not defined $sock) {
   ... Handle error ...
}

... $sock is connected. $host and $post are available ...
