Title: DNS Transport over TCP - Operational Requirements Author: J. Kristoff, D. Wessels Status: Best Current Practice Stream: IETF Date: March 2022 Mailbox: j...@dataplane.org, dwess...@verisign.com Pages: 29 Updates: RFC 1123, RFC 1536 See Also: BCP 235 I-D Tag: draft-ietf-dnsop-dns-tcp-requirements-15.txt URL: https://www.rfc-editor.org/info/rfc9210 DOI: 10.17487/RFC9210 This document updates RFCs 1123 and 1536. This document requires the operational practice of permitting DNS messages to be carried over TCP on the Internet as a Best Current Practice. This operational requirement is aligned with the implementation requirements in RFC 7766. The use of TCP includes both DNS over unencrypted TCP as well as over an encrypted TLS session. The document also considers the consequences of this form of DNS communication and the potential operational issues that can arise when this Best Current Practice is not upheld. This document is a product of the Domain Name System Operations Working Group of the IETF.
