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. -- Arun Khan -- Arun _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
