I am migrating a bunch of services from my Synology to OpenBSD ; DHCP Server being one of them. I have configured quite a few DHCP reservations over time. And I would like a better way to migrate them to dhcpd(8) than copy & paste ; or rewrite from scratch.

Force OpenBSD to use unbound(8) DNS resolver in DHCP client mode

By default, a DHCP client gets an IP address, a network gateway and a DNS server. That’s fine most of the time. But if you own an OpenBSD cloud instance that has to use DHCP to get online, you might not be satisfied with the domain-name-servers option provided by your DHCP server. Hopefully, OpenBSD provides an easy way to force your DNS: # vi /etc/dhclient.conf (...) prepend domain-name-servers 127.0.0.1; Since then, OpenBSD will use our DNS resolver.
