+  *I makes the BIND9 file messy.  The DDNS entries are all over the place in the zone files with different timetolife headers all over the place too.
+  *One had to take greater care to freeze Bind9 when adjusting zone files as DHCP could be writing to it. With Bind in a Docker container, I just restart the container after adjusting the zone file.
+  *I just static IPv4 addresses for my main home server services and manually define the domain names in the Bind zone files where required.  The dynamically defined DNS is simply not important for me.
+  *Other less critical non-server addresses that I want a constant LAN IP I define as static in Kea.
+  *Whilst I expect DDNS certainly has some benefits the use of simple setup of back up of DNS and DHCP is much more beneficially to me.  I run my main home server and NAS and a separate router service focused server. Both of these run Kea and Bind in Docker containers in back-up mode.  If I fiddle with either machine the other provides reliable backup DHCP and DNS. This is much more beneficial to me than DDNS.  If DHCP or DNS are unavailable on my home network it can be very confusing, difficult, time consuming and frustrating to make it work again.  Backup DHCP and DNS on my home server system is simply so much more beneficial than DDNS.
+There are more references on building a home router and related here: [[https://wiki.kptree.net/doku.php?id=linux_router:dns_dhcp#main_references_used_2017|Main references used]], sadly some of these already suffer from link rot even though the information was still relevant.
