I have a snippet of code that looks like this: 
foreach $line (@connections) {
        if ($line =~ /^\s*(\d+\.\d+\.\d+\.\d+):\d+
                  \s*->\s*(\d+\.\d+\.\d+\.\d+):\d+
                  \s*->\s*(\d+\.\d+\.\d+\.\d+)/x) {
                $client_ip{$1}{$iteration}++;
                $vips{$2}{$iteration}++;
                $frontend{$3}{$iteration}++;
        }
}

(This collects information on a F5 BigIP loadbalancer, for those of you who are curious).

Is there a better way I can do the (\d+\.\d+\.\d+\.\d+)? As you can tell, I'm just trying to match for a numeric IP address.
