Posted by Harith on Friday, February 5, 2010 · Leave a Comment

Namebench use to find out the fastest DNS servers available for your computer to use. Namebench run benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation.

This is the result from my benchmarking

I got Google Public DNS is the fastest and followed by P1 DNS server... maybe Google DNS server it the fastest in term of speed, but from my experience, Level 1 (4.2.2.1,4.2.2.2,4.2.2.3,4.2.2.4) DNS server the fastest propagated DNS.

To install:-

Download here.

tar -zxvf namebench-1.0.5.tgz
cd namebench-1.0.5/
python setup.py install
./namebench.py
