Use the caching only name server on your computer. No need for external DNS servers. Use Bind / Named service.
Harshal, do setup Bind / Named service. At this point you have two options, use an external DNS server like http://open-rsc.org or setup Bind / Named to query directly the root servers. The latter may work out to be a bit slower.
How about using both? List the default MTNL nameserver in resolv.conf followed by the local one. You can set the timeout and no. of attempts in resolv.conf with:
-x- options timeout:<m> attempts:<n> -x-
I have no idea what would be optimal values for these parameters. The defaults according to resolv.h (RES_TIMEOUT=5 (seconds) and RES_DFLRETRY=2) are too conservative by broadband connectivity standards. Perhaps they were designed for dial-up users.
