This document describes an experimental TLS extension for the in-band transport of the complete set of records that can be validated by DNSSEC and that are needed to perform DNS-Based Authentication of Named Entities (DANE) of a TLS server. This extension obviates the need to perform separate, out-of-band DNS lookups. When the requisite DNS records do not exist, the extension conveys a denial-of-existence proof that can be validated.
This experimental extension is developed outside the IETF and is published here to guide implementation of the extension and to ensure interoperability among implementations.
