Hi folks 

With help from this list I recently updated my DNS configuration to provide for a primary and secondary DNS server where the primary DNS server is my host inside my domain and the secondary server is provided by AT&T

I discovered that the secondary server on file with my registrar  was wrong so I got the right data  and they claim to have created a glue record but I'm still getting that host is not responding

 

would some kind soul direct me to a coherent glue (or duct tape) record test?

also, given some domain name how do you know which top level domain name servers should be the first set that you query to locate your domain in question??
