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.
Okay I did not know that it comes with a preloaded set of IP addresses.
I just downloaded root.zone to find out the same :-)
$ cat root.zone | grep
"[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}" | head -n5
a.nic.ac. 172800 IN A 64.251.31.177
b.nic.ac. 172800 IN A 78.104.145.37
dinis.ad. 172800 IN A 194.158.64.7
dns2.ad. 172800 IN A 194.158.64.8
dns3.ad. 172800 IN A 194.158.64.9
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.
Sure will give it a try.
