We previously looked at how to add Google Public DNS to your home network, and also how to setup OpenDNS on your Router. Today we’re going to test them and a few others to help determine which is fastest.
1. Download and run Namebench from the Google Code site…no installation is required. The cool thing about Namebench is it’s cross-platform and will run on Windows, Mac, and Linux.
2. When you first kick off Namebench, you’ll see OpenDNS, option to include Google Public DNS, and your local IP DNS server addresses. According to the developers, the default options should be fine for most users. Just click on Start benchmark.
Another thing to keep in mind is to make sure you or anyone on your home network isn’t downloading large files, watching Netflix, or using a torrent client before running the test.
3. Wait while the scans take place…about 5 minutes in our tests. After it’s done your default browser opens up with the results.
4. There are charts and graphs that include detailed information on different tests that were run.
5. If you run Namebench consecutively there will undoubtedly be different results. The developers advise to go with the first test you run. The more times you run it, you’re repeating the queries and will skew the results to the name server that is closest to your location.
6. One way to work around this is to change between the Alexa and your favorite browser history source.
7. After switching to the Alexa dataset from browsing history, we got a result that was more comparable to the first time we ran it.
8. Namebench also includes a feature to export the results to a comma separated Values (CSV).
If you’ve been experimenting with different DNS services, Namebench is a helpful utility for finding the fastest one. There are other free DNS speed testing utilities out there and we’ll be taking a look at them in future articles.
