Name: New DNS Delegation

Description

There is a desire to have better methods for parent zones in the DNS to advertise DNS nameserver capabilities and zone features to resolvers.
Extensible Delegation for DNS is an initial technical specification, format, and basic operational considerations for a new DELEG RRtype.
It has been discussed at a DNSOP WG virtual meeting in January 2024.
The DELEG RRtype is expressly designed to be easily extensible for any other information that might be useful in a DNS delegation, such as transports and capabilities of the child name servers.

The intent of this BoF is to discuss better delegation methods for parent zones, starting with draft-dnsop-deleg as a basis for discussion.
In addition, the BoF will discuss additional capabilities that beyond current NS-style delegation, such as aliasing delegation with other domain names, delegating DNSSEC management to operators (i.e. DELEG alias to SVCB containing a DS record), specifying encrypted transports, and so on.

This BoF will help people outside the DNS ecosystem understand how this new form of delegation might affect their use of the DNS.
It will be an opportunity to hear already-proposed delegation capabilities as well as to brainstorm on new capabilities.
