The DNAv4 draft does determine when the host needs to get some
configuration information from a DHCP server.  The process for that is
governed by the DHCPv4 specification, though the DNAv4 spec does describe
the state that the DHCPv4 client should be in (INIT-REBOOT, etc.).

Ah.  This definition is perhaps misleading. Is there a definition for
"Attachment Point" that we could substitute for it?

We will change the text to refer only to "Attachment Point".

Great.  We will new definitions for "Attachment Point", "Link Up" and
"Link Down" and will then post all the terminology to the list.
