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.

1. 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.
