Alternative DNS ServersThe other day, a friend and I where making fun of somebody who is known to say that the DNS is always at fault. Since no normal human being knows what dig is, let alone how to use it, we thought of building a mail to DNS gateway as a joke. Anyhow, the whole thing petered out and we forgot about it.

It occurred to me again a few minutes ago, however, and I thought: nah: that's low-tech. How about DNS over Twitter?

Well, somebody's already been there, and done that. At least the other way round: twitter via DNS.

At the time of this writing, my last tweet can be had via the DNS. A DNS gateway to twitter, located at the zone will answer with a TXT record if you query it for a resource record named after the Twitter user:

$ dig txt
    ;; ANSWER SECTION:  10      IN      TXT     "@unixtippse while true\; do\; sleep 120\; done" "Sat Nov 28 15:12:12 +0000 2009"
    ;; Query time: 616 msec

Dan Moore wrote this gateway, and you can read more about it here.

I'm still chuckling. ;-) I should have thought about this for my book.
