My friend Glenn Fleishman has written an excellent ebook called “Take Control of Your Domain Names“. You can download a copy of the book for $10 here. Even though I have been doing this Internet thing for a long time, there were still a few things that I learned from his book, including methods to setup dynamic DNS, how some registrars allow you to set various DNS parameters such as TTL, and other technical topics. For people who are new to being master of their own domains, this is a terrific resource that gives you sensible, step-by-step instructions and great advice.
