DNS question: Finding just my domain

[Matthew Carpenter]

Hi Joel-

It's about responsibility and records, and each DNS system and entry has it's own.

The upstream DNS server doesn't keep track of the A record for your domain, just the responsible DNS servers who would have it.  If your local DNS servers are responsible for the mydomain.com zone, they will not (unless configured otherwise) check with any other DNS servers for the authoritative answers for mydomain.com.

mydomain.com, while defined for many different things (SOA, NS, MX, etc...), does not have an A record defined unless explicitly told so.  What would you have DNS hand out for the mydomain.com record?  Does that work for everyone?  

Keep up the learning (and especially the living :)
Good to work with you on this list.

Matt
