Domain Name Speed Benchmark

A unique, comprehensive, accurate & free Windows (and Linux/Wine) utility to determine the exact performance of local and remote DNS nameservers . .

For MTNL Mumbai :

Conclusion :

...
System nameservers are NOT ordered for best performance!
Windows uses DNS servers in the order they are listed under the network adapter's properties, or when obtained automatically from an ISP, in the order provided by the ISP. Windows will fall back to using the second, third, and other nameservers only when the first listed nameserver fails to respond. So if the first nameserver happened to be very slow, but working, everything would be slowed down. Consequently, the order of nameserver listing should match their order of decreasing performance . . . but this is not how this system is currently configured:

In this most recent test, a faster nameserver was listed in order after a slower one.

The following table shows the order of this system's usage of its configured nameservers versus their comparative performance ranking:
