In our guest network I have started seeing a side effect triggered by clients such as iOS 14 devices hat use MAC address randomization When a device is assigned a DHCP lease, then leaves the network to return later in the day within the address lease period, it tries to reconnect with a new MAC address at the same time re-using the previously leased IP address This causes an "IP address conflict" situation to be triggered and reported from the DHCP server on our MX - which I guess, theoretically is correct given the client behaviour. I know MAC address randomization can be disabled on corporate devices, but how to handle guests are another matter. One "solution" is of course to stop the reporting of IP address conflicts but sometimes this can be important to know about.
