I agree that if EVERYONE ran their own dns server it could potentially create excess traffic to root servers. That was the point to having ISP based servers, that way some of the redundant dns traffic would remain on the local ISP network and not transverse to internet query. AT present I run my own internal caching DNS Server which points to my ISP's DNS server, i have always noticed a slight lag when directly querying root servers.
