DNS Issues
From BE Usergroup Technotes
If you are having DNS issues like slow or out of date responses you might consider using alternative (3rd party) servers. You should be aware that by using 3rd party servers you are allowing the third party to record your domain queries and (in the case of OpenDNS) redirect incorrect domains to search pages.

Benchmarking
Here is a benchmark performed on 13/12/2009
Remember that you don't want to use the servers due to be decomissioned or the PTR resolvers! They are included just for information.
Red = Cached Response time - Green = Uncached Response Time.
