DNS Primer

If you’ve ever been interested in how your email gets from your computer to someone else’s, or how your browser knows how to load up a web site, you need to read Dan Benjamin’s excellent DNS primer at MacDevCenter. It’s geared toward Mac OS X users, but anyone can learn the basics of DNS, IP addresses, routing, and all that other techie stuff that makes the Internet work, boiled down in to simply terms by Mr. Benjamin (of Hivelogic/Hiveware fame).
Oh, and hire this dress-code-aware guy, if you have the need. Too much talent to not be getting paid well by someone, somewhere.
