Hi Ben,

Thank you for the review!
Comments inline.

>Security Issues:

>The security section is, if anything, too detailed, as it describes attacks
that are not meaningful to the security of the system.  I would shorten this
section.

Would you be able to elaborate on this?
Currently the section describes:

- the first paragraph: an attack vector which leads to service
degradation or complete DoS for the endpoint;
- second paragraph: an attack vector leading to DoS for the server
infrastructure.

Anything in particular you consider not very relevant for the security
of the system?

As the privacy section of both this draft and
ietf-v6ops-dhcp-pd-per-device mentions, the privacy properties of the
proposed solution are similar but better than ones of DHCPV6 IA_NA.
So privacy-conscious clients should either consider implementing this
specification instead of DHCPv6 IA_NA (or choose not to implement
DHCPv6 at all, but such statement would be clearly out of scope of
this particular draft..)

This was discussed by the WG extensively. The reason is explained in
the pd-per-device draft, so we added a reference to clarify that
(we've just submitted -10).
