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:

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?
