You forgot ntlmv2(1). Try this: 
#!/usr/bin/perl

use LWP::UserAgent;
use HTTP::Request::Common;
use LWP::Debug qw(+);
use Authen::NTLM;
use strict;
use warnings;
ntlmv2(1);

my $url = "http://10.1.1.1";

my $ua = new LWP::UserAgent(keep_alive => 1);

$ua->credentials('10.1.1.1:80', '', 'myDomain\\user', 'password');

my $req = GET  $url;
print "--Peforming request now...---------\n";

my $res = $ua->request($req);
if ($res->is_success) {
    print $res->content;
} else {
    print "Error: " . $res->status_line . "\n";
    print $res->headers()->as_string(), "\n";
}
exit 0;
