So, they don't use IP Telephony then? You're aware you can add whatever you want into DNS, it doesn't have to mean anything that computers understand right? you /could/ make your A records the intro to Star Wars- but nobody will be able to use your site. TXT is a much better option imho, or.. y'know, not doing this.

A lot of VoIP deployments simply ignore the whole DNS side of things, or at best use an A record. Especially in wholesale, it's IP only (using domains breaks some things), and authentication is based on IP, too. (Source IP on a UDP packet - very secure.)

TXT isn't an option because the records themselves are unsorted. Use the above command without the pipe to sort looks weird, but not as weird as TXT would.

Unfortunately our DNS service doesn't allow NAPTR records, so we had to go the TXT route. Here's a large wooden object:

dig +short txt log.netkine.com | sed $'s/\" \"/\\\n/g'

What happens if someone chops up binary data such as a copyright movie file BASE64 encoded into DNS text records? Does all the DNS operators with that in the cache become illegal file sharers then?

Not binary data but: http://decss.zoy.org/

Loot at entry 9, they use a similar hack to distribute the DeCSS (DVD DRM decryption program) source code through DNS.

> Mark Baker noticed that you could do the request to any nameserver. Which means for instance that the DeCSS source code is available from the DVDCCA's nameservers !
