Product Link : Namebench 1.3.1 (Open Source)
When you try to connect to another computer on the Internet, you may take the simple act of entering a server name, such as www.macobserver.com, for granted, but there’s a lot happening behind the scenes to connect your computer to another computer. As you may know, the networking equipment that handles Internet traffic prefers to deal with numbers, not names. For example, www.macobserver.com maps actually 220.127.116.11, but of course nobody wants to remember that.
Fortunately, there’s a system called Domain Name System (DNS) whose job it is to translate easy-to-remember names to the numbers that routers and other networking equipment like to use. In the old days, you may have had to configure this value manually, but this value is typically assigned automatically, especially if you use DHCP. However, this DNS server may not be the best or fastest one you can use. namebench can help.
namebench is a utility for Mac and Windows (there’s also source available if you’d like to compile it for another platform) that will help you find the fastest DNS server in your area. This can be beneficial for activities such as browsing the web, which typically involves opening many network connections and resolving many different addresses.
When you start namebench, the IP address of currently configured name server is filled in. If you’d like to include other name servers in the test, you can enter them here. You are also given the option to include global DNS providers, such as OpenDNS and UltraDNS, as well as the best available regional DNS servers. You can also make sure DNS lookups are not being censored, and share the results of your test to help speed up the Internet for everyone. You will also be asked for your location, the relative performance for a health check (Fast or Slow) the source of the upcoming DNS queries, and the number of queries. The source of queries is important, if you choose a browser you are using, it will tune the results to your surfing habits. You can also use another source, such as top Alexa sites, but the results will be less personalized.
Results of namebench Tests Reported in Your Web Browser
Once the test is complete, you will be presented with the results. The most obvious will show the fastest DNS server available, and how much faster it is than the one your currently using. If the one you are using is the fastest, this will also be reported. namebench will reports the minimum, maximum and average amount of time a lookup took, as well as if any timeouts (TO) occured. Some additional notes about each server, such as NXDOMAIN hijacking, will be noted. NXDOMAIN hijacking means that an ISP, rather than report an error if a name can’t be found, will show their own search page and/or advertising instead. Many nice graphs showing the performance of the tested DNS servers are also shown.
