At any rate, boot time is too early, since you don't know your
ISP-assigned address at that point.  You really need to delay until DHCPv4
gets a lease.

You don't need to reboot the router, it can renumber just fine.  You need
to reboot all the client devices (unless they implement DHCPv4 force renew
with nonce authentication, aka RFC 3203).

I'm not saying it's a bad idea, just pointing out some of the edge-cases
that you will need to consider in order to get a robust implementation.
