Hi Tommy, comments in-line below…

On 26/03/2021, 22:38, "Add" <add-bounces@ietf.org> wrote:

If I am following your proposal correctly, you are saying change “designated resolver” within DDR to be “designated caching resolver” so that if/when Adaptive or any similar draft defines the concept of a resolver designated for a set of names, it can be called “designated authoritative resolver” without needing at that time to refine names with DDR.

Is that correct? Or do you see the different cases within DDR as needing two distinct names?

That is correct.

A previous, now expired draft https://tools.ietf.org/html/draft-pauly-add-resolver-discovery-01, had the concept of a designated resolver for a specific zone (section 2 – terminology) and the current draft draft-ietf-add-ddr has a designated resolver concept for a resolver “designated by another resolver for use in its own place”

I am suggested making clear in the name whether the designated resolver is authoritative or caching.

Cheers, Jim
