This memo arose from discussions in the DNSIND working group of the IETF in 1995 and 1996, the members of that working group are largely responsible for the ideas captured herein. Particular thanks to Donald E. Eastlake, 3rd, and Olafur Gudmundsson, for help with the DNSSEC issues in this document, and to John Gilmore for pointing out where the clarifications were not necessarily clarifying. Bob Halley suggested clarifying the placement of SOA records in authoritative answers, and provided the references. Michael Patton, as usual, and Mark Andrews, Alan Barrett and Stan Barber provided much assistance with many details. Josh Littlefield helped make sure that the clarifications didn't cause problems in some irritating corner cases.
