Y’know the script approach sounds like a good idea.
I also have an OpenBSD box similar to what you describe, but I run ISC dhcpd and BIND because it’s the only setup that does old-school dynamic DNS where the dhcp server sends zone updates to BIND when a lease happens.
But I hate BIND, and not to mention this setup doesn’t work with DHCPv6 (no idea why, it should in principal…) maybe I should just do the “script to read the leases and generate the zone file” approach instead.
The world has been waiting for a DHCP and content DNS server that simply share a common database back-end, meaning no notifications/updates/scripts, for decades. See https://news.ycombinator.com/item?id=44395279 for more.
