rootserver info

[kalyanasundaram S]

Hi all,
  Cant we start the dns server with out rootserver info. (root.hints) If i completely delete this file dns fails to come up. I wanted to resolve only the internal name. I dont want to resolve other names (like google.com, yahoo.com). 
I have seen in the code as well in some place these root server info being hard coded. What for that being used? 

Thanks,
  -"kalyan"
