Internet Engineering Task Force (IETF) O. Gudmundsson Request for Comments: 7218 Shinkuro Inc. Updates: 6698 April 2014 Category: Standards Track ISSN: 2070-1721 Adding Acronyms to Simplify Conversations about DNS-Based Authentication of Named Entities (DANE) Abstract Experience has shown that people get confused when discussing the three numeric fields of the TLSA record. This document specifies descriptive acronyms for the three numeric fields in TLSA records. This document updates the format of the IANA registry created by RFC 6698. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.

Introduction During discussions on how to add DNS-Based Authentication of Named Entities (DANE) [RFC6698] technology to new protocols and services, people were repeatedly confused as to what the numeric values stood for and even the order of the fields of a TLSA record (note that TLSA is not an acronym but a name). This document updates the IANA registry definition for the TLSA record to add a column containing an acronym for each specified field, in order to reduce confusion. This document does not change the DANE protocol in any way. It is expected that DANE parsers in applications and DNS software can adopt parsing the acronyms for each field. 2. IANA Considerations This document applies to the "DNS-Based Authentication of Named Entities (DANE) Parameters" registry located at <http://www.iana.org/ assignments/dane-parameters>. IANA has added a column with an acronym to each of the sub-registries. [RFC6698] and this document are the referenced documents for the three sub-registries. As these acronyms are offered for human consumption, case does not matter; it is expected that software that parses TLSA records will handle upper-, mixed-, or lower-case characters as input.
