It appears our cat does regular patrols of the estate. Here it is being caught 4 different times overnight walking the same route by our driveway security camera. Which isn't there for security so much as to watch the cats patrolling the section

At about 1am this morning something on our network made about 6000 DNS lookups, very odd for that time.

Looking at the logs, its bloody hundreds of requests to time.google.com and to various tplinkcloud.com domains and ntp domains.

Very suspicious, but I have nothing really to go on to hunt the device responsible.

And our IP address changed over night.
