If you are a regular reader of the blog you may have read the following articles about DNS (Domain Name System) and how changing your default DNS settings on your PC to a service such as OpenDNS or Google’s Public DNS can result in a faster (and safer) internet experience. For example I use the DNS settings that is provided by OpenDNS on all of my computers.
The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day. – Google Public DNS
When I composed those articles I wondered how many people actually followed up and changed their DNS settings, for fear they would mess up their computers?
Today I ran across a small software utility called DNS Jumper that you simply download, run, and mouse click a button to select which DNS service you would like to use. This little utility does all the work for you. If you desire to return to your default DNS settings, you simply mouse click on DNS Default and your settings revert to the original settings. This utility is portable and makes for a nice addition to the tech toolbox.
