more bind questions

I'd also like to add that obviously, the actual name of my real domain is being substituted for mydomain in all of this.

So, I looked at the man page for nslookup, and it said I can find out about a host using a specific dns server from a command line. Knowing that dhs.org has 2 servers ns1.dhs.org, and ns2.dhs.org, I typed in the following on the command line on the sun-os box where I have the ssh account.

Judging that nslookup worked in the same way on my box (there is no man page), I envoked it exactly as mentioned, and got the following results.
