The Pi won’t change it if the router is allocating it via DHCP if that ip is reserved for that MAC address. I have half a dozen Pi’s used for different purposes and the IP address never changes when it’s reserved.

The router allocates the IP address for a MAC address, it doesn’t allocate a MAC address. The device “publishes” a MAC address, which usually is hardware bound, but can be spoofed intentionally (or unintentionally, as in my case), in which case the router wouldn’t have an IP address assigned to the …
