For the following test, we have a simple webserver listening on Port 8810 for all interfaces. Port 12345 does NOT host anything. Following is the script we use for reproduction: use strict; use warnings; use LWP::UserAgent; my $ua = LWP::UserAgent->new(); my $result=$ua->get("http://localhost:8810/"); print "(DNS
