Title: Limiting the Scope of the KEY Resource Record (RR)
Author(s): D. Massey, S. Rose.
Status: PROPOSED STANDARD
Date: Dec 2002
Length: 20947
Updates: RFC2535
This document limits the Domain Name System (DNS) KEY Resource Record (RR) to only keys used by the Domain Name System Security Extensions (DNSSEC). The original KEY RR used sub-typing to store both DNSSEC keys and arbitrary application keys. Storing both DNSSEC and application keys with the same record type is a mistake. This document removes application keys from the KEY record by redefining the Protocol Octet field in the KEY RR Data. As a result of removing application keys, all but one of the flags in the KEY record become unnecessary and are redefined. Three existing application key sub- types are changed to reserved, but the format of the KEY record is not changed. This document updates RFC2535.
