Picking the best outside DNS Server for forwarding role.

Need to point my DCs to outside DNS for all forwarding queries as opposed to using root hints. Suggested practice is using your ISPs DNS, however I would like to know a comprehensive way to measure query response performance.

Sorry forgot to answer your second part of your question. I suggest doing some tests with the dig tool where you can specify exact DNS server and query wanted and you get also exact response time measurements.

dig @8.8.8.8 www.google.com A
dig @208.67.222.222 www.google.com A

Open in new window

give results from google public dns and opendns for example and if you have properly installed dig (i.e. with hint servers) you can leave out the @8.8.8.8 part and it'll go through the hint servers.
