Hi ADD,

A question on Designated Resolver terminology.

The draft Adaptive DNS Resolver Discovery https://tools.ietf.org/html/draft-pauly-add-resolver-discovery-01#section-2 has the following definition:

“Designated Resolver:  A DNS resolver that is designated as a responsible resolver for a given domain or zone.  Designated resolvers use encrypted transports.”

I do realise that this draft has expired on 14th January.

Whereas https://www.ietf.org/archive/id/draft-ietf-add-ddr-00.txt terminology has this definition:

“Designated Resolver:  A resolver, presumably an Encrypted Resolver, designated by another resolver for use in its own place. This designation can be authenticated with TLS certificates.”


Does this mean that the earlier definition is no longer in use, perhaps because the draft has expired? Hence does the term Designated Resolver now only apply to a Recursive Resolver?

I believe Apple is using some of the concepts detailed in https://tools.ietf.org/html/draft-pauly-add-resolver-discovery-01. If there is an implementation of the earlier (expired) draft will this be updated to reflect the change in usage of the term Designated Resolver?

Jim
