Bind Help - NS Lookups timeout

I don't think that you understood what I was asking.  
My DNS servers are resolving my own domains (ie. ionosphere.net) just fine.  That's not the problem.  The problem is that I am not able to use my DNS servers to resolve domains that I don't host.   Using the hints in named.root.

Try doing an nslookup (or dig) --using-- ns1.ionosphere.net as your name server, and lookup the A records for covad.net, then try to do the same thing looking up the A records for yahoo.com.

One will work, and one won't.  This is just one example.  We have several domains that -do- work, and several domains that -do not-.  This is, of course, causing a lot of problems.  Mostly with our email servers which use our own DNS servers for domain lookups.

What I am trying to figure out is.. why do the internic root servers (in named.root) work for some domains, and not others??  What am I missing?

Thanks!

  Works fine from here:

  BTW:  Stop using nslookup, use dig instead.
