I gave the example so that we are not blind to what might be happening
behind the scenes.
Personally, I use my own DNS server (bind) built into the gateway.
I have a doubt here, If your DNS server does not have a cached domain name
where is it going to go and look up the domain name ?
The "root" DNS servers provide the NS for the TLD and the first level
sub domains under each TLD.
If a domain name is not cached then the NS records are fetched
starting @ the "root" servers. The file "root.hint" in bind
installation is the provide the IP numbers for the "root" servers.
Read up on how DNS works - really if you are serious about it. There
are a couple of informative O'Reilly books on the subject. Although,
for starters you can start here <
http://www.tldp.org> and browse
through the HowTos index.
