no - the caching only name server directly queries the root nameservers on the internet (and of course caches the results). The 'only' refers to the fact that the other elements of a dns server do not run - ie, the machine does not have its own internal dns. bsnl, mtnl and vsnl regularly screw up their dns servers, so it is advisable to run ones own as already suggested No- It depends on the zone that you define. If you have a zone '.' of type hint and you provide root servers, then and only then will it refer to the root servers. If instead of root servers you provide any other server it should query that and obtain a non-authorative answer. I dont know how often vsnl/bsnl screw their dns servers but in case of production proxy servers generally you have a local caching server to improve performance. Helps when you have more than 20/30 hits per second. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
