Hello all :)

Is there a script that exist or other wise, where a script can be run on your server to see what domains still resolve. We did a large migration and want to clean house but of course don't want to check a trace and-or lookup for every domain on the server.

I could have sworn, I have seen this script before (or maybe in a dream).

Checking each domain to see if it resolves to our name servers is just way to time consuming.

Thanks,
Amy

You should be able to write one up fairly quickly in your language of choice.

Off the top of my head, for PHP:


<?php
// Set the following to a file that lists one domain per line
$domainsFile = "/path/to/domains.txt";

// Set the following to the IP address of your new server
$serverIP = "0.0.0.0";

// END CONFIGURATION //

foreach (file($domainsFile) as $domain) {
print "{$domain}... ";

if (gethostbyname($domain) == $serverIP)
print "OK\n";
else
print "INCORRECT\n";
}
?>


This should attempt all of your domains to see if they resolve to your new server.
Should take a fraction of a second per domain, depending on your resolving nameserver.
(Make sure you run it with a different nameserver than your authoritative one!)
