Re: Re: Root DNS Server Issues?

  • From: John M. Brown
  • Date: Tue Oct 01 20:00:30 2002

Root servers don't resolve names other than the TLD's.

OTW they don't have data for www.yahoo.com    only for  .com
which will point you towards the gTLD servers (listed below)
which will point you towards Yahoo's name servers.

What names are you trying to lookup ?
