As I understand it, the OP wants to use DHCP static leases.

Better to use '.home.arpa' (RFC 8375).


With dinamic and static DHCP leases you could do:

dhcp-range=192.168.23.2,192.168.23.253

dhcp-host=11:22:33:44:55::66,192.168.23.254

dnsmask will dish out dinamically IPv4 addresses from 192.168.23.2 to
192.168.23.253 and will asign 192.168.23.254 to host with MAC address
"11:22:33:44:55:66'.


Note that the IPs used in 'dhcp-host' don't need to be outside of the range.
