Handling of Unknown DNS Resource Record Types
RFC 3597, “Handling of Unknown DNS Resource Record Types”, is a Proposed Standard document published in September 2003 by A. Gustafsson. It updates RFC 2163, RFC 2535. It has since been updated by RFC 4033, RFC 4034, RFC 4035, RFC 5395, RFC 6195, RFC 6895. The canonical text is published by the RFC Editor.
Abstract
Extending the Domain Name System (DNS) with new Resource Record (RR) types currently requires changes to name server software. This document specifies the changes necessary to allow future DNS implementations to handle new RR types transparently. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
