About Nameservers

[innovative2001]

A NAMESERVER is the program that actually does the work of looking up names. The program IN.NAMED acts as the name server. There is usually one name server for a cluster of machines.

There are three main types of NAMESERVERS:

1) CACHING-ONLY name server does lookups of names, but controls no name records itself.
2) PRIMARY name server not only does lookups of names, but also owns the records for a domain.
3) SECONDARY name server does name lookups and it also backs up a primary name server by providing authoritative answers for a certain domain. Many name servers will combine Primary and Secondary functionality for different domains.

Thats a neat explanation about nameservers which i understood in the first go thanks a lot dude.

And the 3rd and the 4th nameservers are for backup if you have your domains working from two servers while in transition of a transfer. hope i am right about this :D :beer:
