In DNAv4, the "network anchor" identities are defined to include both the IP
address and the MAC address, so that duplication of both would be required
to cause confusion. 

This works as long as the "network anchor" is actually an anchor, not a buoy
-- it cannot also be mobile.

At least with respect to DNAv4, it doesn't appear to matter whether the
"network anchor" is a router or not.  This is, I think an important
advantage of approaches that rely on ARP/ND vs. ones that rely on RS/RA.
