Dear all

 I made a pass on the current version of the draft and have a number of
high level comments / proposals.

1) use the P field as in the registration to indicate whether the node
requests an address or a prefix. In the future, the method could be
extended to obtain an anycast address or a multicast address associated
with a named resource.

2) not to overload the status in the response. The prefix length may be
indicated in a currently reserved space in the GAAO

3) optionally use the address field in the request to indicate the prefix
from which the address should be derived. If not provided, indicate that
the address returned is implicitly used on the interface which was used to
make the request

4) return a prefix length for an address (e.g., /64) if the prefix is on
link so the node may create a connected route

5) in the protocol operation, be clear on what is done for all types of
requests, then what is specific for address, and what is specific for a
prefix. In the text sometimes the term request is associated with "address"
and sometimes with "address or prefix", though in places the intent in the
former case appears to be for prefixes as well..

6) consider using a bit in the request to indicate that the router should
register the address or prefix without a second round (Ratification Phase).
The router would pick the missing EARO field from a default and return the
complete EARO to indicate that the registration succeeded. In that case,
maybe add also an "R bit" to the GAAO like the one in the EARO and rename
the current R bit to avoid confusion.

7) change the term Ratification Phase to "registration phase" with a ref to
RFC 8505 and the prefix registration draft.

I suggest we also start thinking of providing a name (like mDNS) in the
request to ask the router to publish the association of the name and
address. This will be useful for  multicast and anycast as well.

I hope this helps
