Trying to find DNS RFC

[converge]

I have recently run across a couple of folks stating that it is functional to specify a URL as the root record for a domain name instead of an A. I've been looking around through DNS RFCs for a bit trying to find the current specification for exactly what is/isn't allowed for the root record..

Any suggestions for those that have them memorized? Any recommendations on search phrasing for expediting my hunt?

My old copy of O'Reilly's DNS and Bind shows the following RFCs in the Index:
RFC 1035
RFC 1183
RFC 1664
Those may not be current, but they may help you find the any that supersede them.

yeah, I'm reading through 1035 atm, 1183 and 1664 didn't seem to have pertinant data.. but I know that 1035 has been updated considerably so not sure if turning it upside down will yeild the answer I want.

A address Textual Representation is RFC1035, page 20 according to D&B, but I don't think know if that's exactly what you want.

This would be a good place to look:

http://www.dns.net/dnsrd/rfc/ probobly towards the bottom.

TCP Illustrated has a great interpretation and implementation examples of the DNS RFC
