in reply to Dyndns.org Updating Client

I tend to use:

use Socket;
if ($ip = gethostbyname($domain)) {
    $ip = inet_ntoa($ip);
    print "IP address is $ip\n";
} else {
    print "Could not resolve name.\n";
}

Not amazing, but does the job :) I assume you're going out to "whatismyip.com" because the IP address you want is not the box you run the script on?

    I like the code, and the concept. I'll change things when I get home and do an update. I use whatismyip.com because the computer I run the code on is behind a NAT. Then I let the NAT forward ports to my internal computers. Plus, for those that don't have a NAT, it always retrieves the correct world routeable IP address, instead of grabbing the first network card's IP. I believe the above code could easily replace my call to nslookup. Thank you so much :-)
