RFC 9499: DNS Terminology
Recent RFCs 2024-03-21
Summary:
The Domain Name System (DNS) is defined in literally dozens of
different RFCs. The terminology used by implementers and developers
of DNS protocols, and by operators of DNS systems, has changed in the
decades since the DNS was first defined. This document gives current
definitions for many of the terms used in the DNS in a single
document.
This document updates RFC 2308 by clarifying the definitions of
"forwarder" and "QNAME". It obsoletes RFC 8499 by adding multiple
terms and clarifications. Comprehensive lists of changed and new
definitions can be found in Appendices A and B.
