Everyone knows of Google's love for Beta, so it's really something when one of their projects comes out of beta testing. The most recent big thing to come out of Google's beta testing is their public DNS (domain-name system). For those of you who don't know, a DNS is what translates "www.insanetek.com" into our website's IP address of "173.212.208.166." Just about every ISP offers their own DNS, which you're using right now if you haven't changed anything, but that is often times a little slow. Google's public DNS server aims to increase the DNS lookup speed, allowing for faster browsing. I've personally tried out Google's public DNS, and while I didn't do any formal testing, day-to-day use did seem a little faster. It could just be the placebo affect, but I digress. 

If you're interested in trying out Google's public DNS, it's really quite simple. Go to your Network and Sharing Center (Control Panel > Network and Internet > Network and Sharing Center), then click on the link after "Connections:" which will say something like Local Area Connection if you're using a wired computer. From the menu that pops up, click on Properties. On the Properties window, click once on "Internet Protocol Version 4 (TCP/IPv4)" then click on Properties. Toward the bottom (more like the middle) you'll see two options, either "Obtain DNS server address automatically" (will use your ISP's DNS) or "Use the following DNS server addresses:." Click the second option and enter in "8.8.8.8" for the Preferred DNS server and "8.8.4.4" for the Alternate DNS Server. Click ok or close on everything and exit out of everything, and now you'll be using Google's Public DNS Server. Like I said, it's really easy to do, and if you care about speed it's probably worth it to do.
