My ISP’s DNS servers were horrible (Verizon FIOS) so I switched to dyndns.com a while ago. It was quite an improvement. With Google’s announcement about a public dns server I got curious to see if things are better.
There’s a great tool namebench to evaluate DNS performance. It can use your local browser history to determine the set of hosts to tests or some pre-built lists:
I was averaging over 90ms per request — and this is the faster version! This graph is produced by namebench:
So I signed up for OpenDns to see if I could get an improvement. It’s pretty decent. I think it’s been dropped down to 45ms.
