DNS is an integral part of working with the Internet, but what if you don't understand how it works? This course will give you all the insight you need to have a basic understanding of DNS and how it translates http://74.125.224.72/ into http://google.com/! The class is designed for web professionals and almost anyone looking for a walkthrough on general DNS concepts.

"A harder course than I expected, but I did learn from it. I did get a lot of good future reference materials to use as resources as well, so that was good too." - Robert Hoefer
"Excellent class that included a great deal of information, yet in manageable chunks. I learned much more from this class than I do from a typical one, and it was very satisfying. The instructor's weekly lectures really pulled everything together so it was easier to understand." - Kathy Hoffman
