This is interesting work. A couple of questions:

1. What is the value of names for prefixes? It seems to me that in
a large network, the names will end up being useless (most likely
just built from the prefix itself). They will surely not be assigned
by humans.

2. I see that ipv6-address-no-zone and ipv4-address-no-zone are used for
gateways. In my experience, IPv6 link-local addresses are quite common for
first-hop routers, so -no-zone is dangerous. If you receive an RA/PIO message
from a router, of course you know the interface and the router address
automatically, so I'm not quite sure why usergateway is in the data model
for IPv6. It isn't for use by DHCPv6, since that option does not exist.
