      The title says it all... My google-fu hasn't provided a good understanding of this topic so I figured I would ask the community.

      If if matters, I have my home network set up on a pfSense VM with my network segmented into a primary LAN and 2 vLANs. The primary LAN is for all of my PCs and infrastructure devices. The vLANs are for my IoT devices and a guest wifi network. All of the devices that can connect to the primary LAN have assigned IP addresses and the DHCP server is set to deny unknown clients.

        Bootp is an ancient protocol that was replaced by DHCP. I doubt you would have anything that uses it.

        I haven't lost my mind. It's around here...somewhere...

          Hey Joe, found this explanation in this Cisco documentation. I hope this helps.

          This feature is beneficial when there is a mix of BOOTP and DHCP clients in a network segment, and
          there is a BOOTP server and a Cisco IOS DHCP server servicing the network segment. The BOOTP
          server is configured with static bindings for the BOOTP clients and the BOOTP clients are intended to
          obtain their addresses from the BOOTP server. However, because a DHCP server can also respond to a
          BOOTP request, an address offer may be made by the DHCP server causing the BOOTP clients to boot
          with the address from the DHCP server, instead of the address from the BOOTP server. Configuring the
          DHCP server to ignore BOOTP
