You don’t need to run DHCP services on your router. If you’re running large infrastructure, arguably, you shouldn’t, and should instead run a DHCP server on a server, and leave your router’s resources for routing.
> This has become especially bad since most devices started using a new mac address for every connection. It means an apple device going in and out of range of a wifi point all night can easily create thousands of leases
Apple MAC address privacy generates a random MAC per SSID. It doesn’t generate a new random MAC every time it reconnects to the same SSID. This would be pretty terrible as far as user experience goes too if they did.
