For those users who have thoughts about the best DNS server for their locality, there is a nice app in the repository, called namebench which will check lots of DNS servers, including the ones currently set on your PC, and report back which is the fastest for your location.
Having run it here, while using the OpenDNS server, it reported back that Google's 8.8.8.8 is the fastest of those available to me ..... 57% faster than OpenDNS, and some 41% faster than my ISP DNS.
It also gave a recommended set up of three DNS IPs ....... Google and two from my ISP.
It does seem to be a rather cool app, but I also wonder if it is biased in any way .....
Try it!
