There is a plannned server for India.
This can test the performance of your current ISP DNS, versus a number of popular public DNS servers, including opendns and google DNS.
Why would you choose OpenDNS?
- Your ISP dns is unreliable or slow
- You want the filtering options
To be honest, if your ISP techs know their job, and are not being made to stretch hardware that really isn’t up to the task, your ISP DNS should beat everything else, as it’s so much closer.
