Most people use the default DNS settings provided by their ISP, and while they are usually sufficient for most purposes, there are plenty of free options out there, like OpenDNS and Google DNS. Namebench is a free app that checks to see whether your current settings are optimized and, if not, which free option is best for you. Here's how to use it: Download and install Namebench. Fire it up and choose your settings. Keep the top two boxes checked. If you're concerned about network censorship, check the third box, and if you want to help the developers, check the last box. You can tweak the rest if you're outside U.S. or want to experiment with different browsers.
