-Further to this I am no looking at backups for both these services on my local area network.  Whilst these services worked reliably well, when ever I shutdown the the router with DNS/DHCP servers my LAN would stop working. Hence the need for back-up DNS.  Many of my home server applications now are set up to operate via https via Traefik and this also relies upon correct local DNS resolution.  Hence DNS is even more critical.  The DHCP server is less critical, however all the IT equipment that relies upon DHCP will not function without this service.  Most my critical services have static IP address.+Further to this I am not looking at backups for both these services on my local area network.  Whilst these services worked reliably well, when ever I shutdown the the router with DNS/DHCP servers my LAN would stop working.

 (2022) ISC has a newer DHCP software called Kea that is designed to replace ISC DHCP. Kea was primarily developed around 2014-2020. They also are currently developing a monitor for Kea and Bind9 called Stork.  A future plan would be to review and replace ISC DHCP with Kea and also implement Stork. (2022) ISC has a newer DHCP software called Kea that is designed to replace ISC DHCP.
