Another Update: I've seen on Slashdot recently that nslookup is going the way of the do-do. Try "host" instead...
Update: OK, I've been doing this entirely too difficultly.
The simple way to use nslookup is in a form similar to this example:
nslookup www.test-this-host.ca ns1.test-name-server.com
nslookup mx.ivydsl.com 216.113.192.3
(i.e. nslookup [host to search for] [server to query (optional)]
Adding a "-d" option returns as much info as nslookup can get for you. Like list of hosts and stuff.
nslookup -d www.test-this-host.ca ns1.test-name-server.com
A few words on using NSLOOKUP to get the information for a domain registration from the DNS system.
Start nslookup in interactive mode:
NSLOOKUP
Then set the server to query:
server=xxx.xxx.xxx.xxx to be the same as the DNS server for the domain that you are looking up.
ls-a...

There is the "dig" command in Linux. It is supposed to query all the info from the responsible DNS server.
