What is dhcp option 66. Dec 13, 2022 · There is a blink camera system with a blink sync module that is listed as blink sync in the device list and in the log it is blink dhcp. Literally, within 90 seconds of turning this off all buildings were back on and running normally again.

Once that address is assigned it will not hand out additional addresses.
