As there is a very minor DNS part in the whole document, this should be an easy review.

I have been selected as the DNS Directorate reviewer for this draft.
For more information about the DNS Directorate, please see

This document specifies very little in terms of DNS interaction. The only
mention I detected is this:

> 5. Allocation of a Global Unicast Prefix for SIDs
> At the present time, AAAA and PTR records for addresses assigned from this
block SHOULD NOT be installed in the global DNS [RFC8499].

Keeping my lack of understanding of SRv6 in mind, it sounds fine, or at least

From the DNS point of view, it's unclear why AAAA and PTR record types were
singled out. IPv6-like addresses can conceivably appear in other record types
(currently at least HTTPS and SVCB), and more types can be added tomorrow. I
would recommend a more generic phrasing, e.g.:

"At the present time, global DNS [RFC8499] SHOULD NOT reference addresses
assigned from this block."

Thank you for your time.
