FWIW, godaddy's dns is different than what is used for godaddy's customers.

Godaddy's dns:

Name Server: CNS1.SECURESERVER.NET

   Name Server: CNS2.SECURESERVER.NET

   Name Server: CNS3.SECURESERVER.NET

A typical customer of godaddy's dns servers:

Name Server: NS07.DOMAINCONTROL.COM

   Name Server: NS08.DOMAINCONTROL.COM
