Next stop a few hundred. on someone elses testbed...
My main issue with hncp (3 years back) is it wanted to assign an IPv6
address to *everything*
and I only have /60s to spare, and I didn't want to assign public ipv6 addresses
to internal routers at all.

I'm rather impressed with how far odhcp has evolved since I last looked and
had some code in it to manage times better but probably not what you want.
In particular I was *really impressed* by the clean interface to netlink.
Netlink is a PITA to deal with.
It could use some more ebpf support.
