Assign aliases to hw address for easier device identification with dynamic ip

le. With router serving as DHCP and providing secondary external DNS if pi-hole device shuts down I am fine, but with DHCP on pi-hole I will have to somehow ensure it is reliably always on

I have had no instances where the router was running and pihole wasn't, unless the power went out at which case I would have had to properly restore power to both any ways for them to both work reliably. Pihole itself doesn't stop working if it is running on a clean environment void of any problems.
