If you assume that DHCP works, you can forget about the link -local addresses, and just do the ARP query from a host on the same subnet. For example, I can tell by the MAC address beginning with that the vendor is "Raspberry Pi Trading Ltd". That's my Pico W and its IP address (assigned by DHCP) is 192.168.1.147. If there can be multiple Raspberry Pis on the subnet, it might be helpful to label each one with its MAC address.
Code:
