Diagnosing DNS problems...?

[jon]

Howdy folks...

So, if ya haven't guess, I get to play sysadmin this week as we're 
trying to get a new project off the ground. Which is fun. However, as a 
web developer, I'm wandering into areas that I haven't really explored...

So... here's where I'm at: I'm trying to get mydns up and running on my 
ubuntu box. No problems there.... however, I'm not really clear on how 
to set up individual records and get 'em to resolve correctly.

What's the best way to diagnose dns setup problems? Is there a good 
tutorial for working through these things?

So... let's say I want blah.huggabear.com to resolve to 69.55.220.101, 
does this dig response look right?
