DHCP Option 43/60 Role in AP and HIST Zero Upline

The lower-off controller address, and the plug-in is done.

AP, IP Intercom does not know where the controller is. Option 43/60 allows the device to get the address of the controller while it has an address, and then calls it to register without field configuration. Zero configurations can significantly reduce start-up times, but be careful that Option sends out -- do not leak the controller's address to VLAN, which should not have been received, creating security risks.
