 To further complicate matters I have 2 Bind9 servers in a master-slave configuration across to separate computers on my LAN as well as 2 separate Kea DHCP servers in a primary-secondary back-up configuration also on 2 separate computers on my LAN. This has worked really well for me.  If one DNS or DHCP server are not functional my LAN operates well, previously without backup is the DNS or DHCP servers were not operational the LAN would loose functionality.  I would need DDNS to function correctly within my backup DNS and DHCP configurations. To further complicate matters I have 2 Bind9 servers in a master-slave configuration across to separate computers on my LAN as well as 2 separate Kea DHCP servers in a primary-secondary back-up configuration also on 2 separate computers on my LAN.
