Understanding nslookup

I'm introducing myself to nslookup among some other tools and trying to learn the ins and outs here.

In doing so, I've come across something odd. I ran a "nslookup all" to see what it would pull from our network, and got this:

Quote:

C:\Documents and Settings\Administrator>nslookup all
*** Can't find server name for address 192.168.1.x: Non-existent domain
Server: e450.ltrkar.telcovebusiness.net
Address: 64.66.82.6

*** e450.ltrkar.telcovebusiness.net can't find all: Non-existent domain

192.168.1.x is the local address of our DNS server. Shouldn't I have gotten the name of that server and information on our LAN? Or am I not understanding this tool correctly?

Its trying to lookup the domain "all", just like it "nslookup antionline.com" would lookup "antionline.com".

For what I think you're trying to do... Type "nslookup" and then when you're inside the program type "set all" ?

Zenger is correct, it is assuming you are asking it to look up the name 'all' (in various incarnations depending on how a few things are set up). What you are probably wanting to do is set the querytype to all (set type=all if memory serves) and then probably an 'ls' to list the domain (most places will have that turned off for obvious reasons). Have a look here:

Kind of hard to read but should give you an idea of the possibilities.

EDIT: this one is handy too: http://elouai.com/nslookup-reference.php

set qt=any to be exact ;)

Or directly on the commandline nslookup -qt=any mydomain.com (works on nt and *nix)

This error message happen when your reserve lookup zone is NOT configured in your DNS server. And then again, if your reserve lookup zone is configured, make sure your DNS server created the PRTY entry in the in-addra-arpa zone! ;)

If you want more help, give me a PM.

You probably mean the PTR record ;)

Do you mean reverse lookup zone?

Yes. He means the reverse lookup zone.

In your case that's probably 1.168.192.in-addr.arpa or 168.192.in-addr.arpa.

Indeed, there's no Reverse Lookup Zone configured on our DNS server. I have no idea why. Guess it's time to check that out!
