GoDaddy auction site nameservers aren't managed by GoDaddy
When I wanted to start working on webintegrity.net, I got a "Server IP Address Could Not Be Found" error message. Then I wanted to check my DNS settings and was told: "We can't display your DNS information because your nameservers aren't managed by us.", but I bought the domain name on auction from GoDaddy...
The DNS is like a map the connects your domain name with your website, email, as well as other settings. You'll want to make sure it has the settings for all of the services you use with the domain. Generally it would be automatically set if the DNS and service are in the same account, but external services would need to be added manually (like if your website and email were from different providers).
