I saw hundreds of thousand threads and blogs on internet about Which is fastest and reliable DNS for broadband?
So, after few hours search I found that the BSNL's own system DNS were fastest for BB (at least as per my search and research ).
Not Open DNS nor the Google Public DNS; it's BSNL's DNS is Fastest and Reliable.
I say so because, I download couple of software and also from RUN command testing.
Take look of few result of mine -
1] From RUN command Attachment 7934
2] From software testing Attachment 7933
I use following software's - DNS Bechmark & namebench
