Summary: This document is ready for publication as a Proposed Standard.

Comments: I would love to see a clarification in 4.1, as follows, but even if the ADs agree, this is RFC Editor note material.

At the very end of 4.1, this new-since-17 text appears:

   The PaC may need to reconfigure IP address after successful
   authentication and authorization phase to obtain an IP address that
   is usable for exchanging data traffic through EP.

At the beginning of 5.6, this new-since-17 text appears:

   A PaC's IP address used for PANA can change in certain situations,
   e.g., when IP address reconfiguration is needed for the PaC to obtain
   an IP address after successful PANA authentication (see Section 4.1)
   or when the PaC moves from one IP link to another within the same
   PAA's realm.

In 4.1, I don't understand WHY the PaC needs to reconfigure its IP address "to obtain an IP address that is usable for exchanging data traffic through EP".

So I'm guessing at what happened, to make reconfiguration necessary. I WAS guessing that this had to do with mobility, but 5.6 lists PaC mobility as a separate reason to reconfigure the IP address, so I'm thinking the 4.1 text must refer to some situation I don't understand (that is not PaC mobility).

If this text could explain why reconfiguration is required when PaC mobility does NOT take place, that would be swell.

I'm also curious about the 4.1 text at the end of the same paragraph:

   How IP address
   reconfiguration is performed is outside the scope of this document.

because I'm not sure what "IP address reconfiguration" actually means in this sentence, but that could be my ignorance - if so, sorry.
