      Until a couple of weeks ago I had been using the Kea DHCP server but hit a bug and was advised here to switch to the ISC DHCP server. I did this, but the ISC DHCP server is not registering hostnames with the DNS server, and I understood that it should. I know the Kea DHCP server does not do this registration.

      Am I correct with my understanding, and if I am, how do I get the DCHP server to register leases in the DNS server?

        @NickJH do you have it checked to register dhcp?

          @johnpoz I enabled it around the time I posted. Do I need to wait until the lease gets renewed before the DNS gets populated.

            @NickJH yeah I would assume that yes it would require the lease to be renewed or offered after you click that check box.. Just force a renew on your client.

              @johnpoz I've just got back from holiday and saw something went wrong as the checkbox still was not checked. Then I realised the box I really wanted was the "Register DHCP Static mappings in the DNS Resolver", so I set that and it immediately worked on a DNS restart.

              Thanks.

                @NickJH well register static, is what you have made a reservation for, that is loaded when unbound loads, so yeah changing the config would be instant because unbound restarted and loaded in all your dhcp reservations.
