I do think that something needs to be said about this, since the issue has come up in implementation. For example, based on the distinction above, a client handling a dynamic update on its own using TKEY would implement the lookup protocol, whereas a DHCP server handling a dynamic update on behalf of the client might implement the registration protocol.

another alternative would be for you to issue an informational RFC about interpretation of IDNA 2008 in light of DYN DNS, would it not?
