Service Binding Mapping for DNS Servers
RFC 9461, “Service Binding Mapping for DNS Servers”, is a Proposed Standard document published in November 2023 by B. Schwartz. The canonical text is published by the RFC Editor.
Abstract
The SVCB DNS resource record type expresses a bound collection of endpoint metadata, for use when establishing a connection to a named service. DNS itself can be such a service, when the server is identified by a domain name. This document provides the SVCB mapping for named DNS servers, allowing them to indicate support for encrypted transport protocols.
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.
