Set your name server up as a primary for your local domain. This will work even for a non-registered domain (but choose your name wisely) As long as resolv.conf is correct and you have all of your client systems point to this name server everything will work fine. It won't really go to your ISPs DNS for non-local lookups, it will go to the roots and from there to the correct name server for whatever domain it is that you are looking up. It will dial into your ISP when it needs to go to the roots (obviously) Caching is automatic and lasts considerably longer than 30 minutes in most cases (determined by TTL of the data returned) Dan -- Dan Busarow 714 443 4172 DPC Systems / Beach.Net dan@dpcsys.com Dana Point, California 83 09 EF 59 E0 11 89 B4 8D 09 DB FD E1 DD 0C 82
