RFC 3755
Title: Legacy Resolver Compatibility for Delegation
Signer (DS)
Author(s): S. Weiler
Status: Standards Track
Date: May 2004
Mailbox: weiler@tislabs.com
Pages: 9
Characters: 19812
Updates: 3658, 2535

As the DNS Security (DNSSEC) specifications have evolved, the
syntax and semantics of the DNSSEC resource records (RRs) have
changed. Many deployed nameservers understand variants of these
semantics. Dangerous interactions can occur when a resolver that
understands an earlier version of these semantics queries an
authoritative server that understands the new delegation signer
semantics, including at least one failure scenario that will cause
an unsecured zone to be unresolvable. This document changes the
type codes and mnemonics of the DNSSEC RRs (SIG, KEY, and NXT) to
avoid those interactions.
This document a product of the DNS Extensions Working Group of the
IETF.
This is now a Proposed Standard Protocol.
This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol. Distribution
of this memo is unlimited.
This announcement is sent to the IETF list and the RFC-DIST list.
Requests to be added to or deleted from the IETF distribution list
should be sent to IETF-REQUEST@IETF.ORG. Requests to be
added to or deleted from the RFC-DIST distribution list should
be sent to RFC-DIST-REQUEST@RFC-EDITOR.ORG.
