    abstract =  {DNS Long-Lived Queries (LLQ) is a protocol for extending the DNS protocol to support change notification, thus allowing clients to learn about changes to DNS data without polling the server. From 2007 onwards, LLQ was implemented in Apple products including Mac OS X, Bonjour for Windows, and AirPort wireless base stations. In 2019, the LLQ protocol was superseded by the IETF Standards Track RFC "DNS Push Notifications", which builds on experience gained with the LLQ protocol to create a superior replacement. The existing deployed LLQ protocol 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.},
