I want to give the Web Architecture of the Decade award to Hover. They have a hidden feature that changes everything when managing domains, which is what they do.#
Here's the feature. They let you put a CNAME where an A record is called for.#
In other words you can use a pointer where previously you could only use a hard-coded address. This makes it possible to switch hardware without having to keep track of every DNS-based reference to it. You can point through a pointer. #
There's no reason not to do this. Their server is going to respond to every request, so they can do a database lookup to find out what IP address goes with the CNAME and return that. All transparently to the requester.#
When someone told me this works, I didn't believe it at first. Now it saves my ass all the time. A feature that every DNS system should support. It's the best kind of feature, it doesn't increase the complexity of the software, and it gives the user more leverage. The rare feature with no tradeoff. #
Congrats to Hover and thanks from a happy user. :-)#

You know those obnoxious sites that pop up dialogs when they think you're about to leave, asking you to subscribe to their email newsletter? Well that won't do for Scripting News readers who are a discerning lot, very loyal, but that wouldn't last long if I did rude stuff like that. So here I am at the bottom of the page quietly encouraging you to sign up for the nightly email. It's got everything from the previous day on Scripting, plus the contents of the linkblog and who knows what else we'll get in there. People really love it. I wish I had done it sooner. And every email has an unsub link so if you want to get out, you can, easily -- no questions asked, and no follow-ups. Go ahead and do it, you won't be sorry! :-)
