+Note that opnSense says "ISC DHCP is end-of-life and no longer receives updates or security patches. It is strongly recommended to migrate to KEA or Dnsmasq.", however, I was unable to locate the information I needed to set up KEA. However, I'm putting my notes below just in case I want to revisit it.
 ==== Using KEA DHCP Server ====

 Restart KEA after this either via the webui, or with the command <code bash>service kea reload</code>
-Again, this is something I found with duck.io, and it did not give attributions, so I don't know. I did find that others said that KEA will only put staticly defined leases, and will not send notification for dynamic.
+Again, this is something I found with duck.io, and it did not give attributions, so I don't know. I did find that others said that KEA will only put staticly defined leases, and will not send notification for dynamic. I did some additional research and it appears the kea-dkcp-ddns service is meant to communicate with Bind9, so that may be something to pursue.
 ===== Testing =====
+All you need here is to find a workstation and renew the dhcp lease, then see if it updates the DNS. The following commands do that for you (command line)
+<code bash>
+# Windows
+ipconfig /renew
+# Unix (just about any of them, including BSD, as root)
+dhclient -r
+# Linux using ifconfig, as root
+ifconfig eth0 down && ifconfig eth0 up
+# Linux, with systemctl
+sudo systemctl restart NetworkManager
+# Linux, with Network Manager, where eth0 is your interface
+nmcli device reapply eth0
+# MacOS (where en0 is your interface, use ifconfig to find the name)
+ipconfig set en0 DHCP
+</code>
+Now, simply check the DNS server to see if it has the dhcp lease in it. If not, check your DHCP and DNS logs to see what went wrong.

+Sorry, I did not keep good track of where I went. I spent a lot of time on [[duck.ai]], but like most AI searches, it gave a lot of bogus information. Here is my 'sorta' list
