A new Request for Comments is now available in online RFC libraries. RFC 8764 Title: Apple's DNS Long-Lived Queries Protocol Author: S. Cheshire, M. Krochmal Status: Informational Stream: Independent Date: June 2020 Mailbox: cheshire@apple.com, marc@apple.com Pages: 20 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-sekar-dns-llq-06.txt URL: https://www.rfc-editor.org/info/rfc8764 DOI: 10.17487/RFC8764 Apple's DNS Long-Lived Queries (LLQ) is a mechanism for extending the DNS protocol to support change notification, thus allowing clients to learn about changes to DNS data without polling the server. From 2005 onwards, LLQ was implemented in Apple products including Mac OS X, Bonjour for Windows, and AirPort wireless base stations. In 2020, the LLQ protocol was superseded by the IETF Standards Track RFC 8765, "DNS Push Notifications", which builds on experience gained with the LLQ protocol to create a superior replacement. The existing LLQ protocol deployed and used from 2005 to 2020 is documented here to give background regarding the operational experience that informed the development of DNS Push Notifications, and to help facilitate a smooth transition from LLQ to DNS Push Notifications.
