Name Server Monitor

Name Server Monitor is DomainTools' powerful name server monitoring technology. Monitor the daily activity of .com, .net, .org, .biz, .us, and .info domains on any name server under 50,000 domains and receive an email notification when there are new and/or deleted domains.

What can I do with Name Server Monitor?

Hosting companies can keep an eye on their competition by monitoring their competitors name servers. You will see how many new sales they are doing, which web sites signed up, who is leaving, and where they are going.

Domainers can monitor their own or friends name server to keep track of which domains they own, which domains they are selling, or transferring.

For fun, you can monitor your favorite website's name server to see when they acquire new domain names and potentially new product launches.
