1. Introduction

During discussions on how to add DANE [RFC6698] technology to new protocols/services people repeatedly have got confused as what the numeric values stand for and even the order of the fields of a TLSA record. This document updates the IANA registry definition for TLSA record to add a column with 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 parser's in applications and DNS software MAY adopt parsing the acronyms for each field, installed base MAY NOT get updated.

1.1. Requirements notation

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].

2. IANA considerations

This document applies to "DNS-Based Authentication of Named Entities (DANE) Parameters" located at "http://www.iana.org/assignments/dane-parameters/dane-parameters.xhtml". Each one of the Sub-registries will add a column with an acronym for that field.

[RFC6698] and this document are both to be reference documents for the three sub-registries.

2.1. TLSA Certificate Usages
