Does your setup distinguish between IoT-ish devices (where you don't know what software is running) and human-operated devices (which would trigger this every time they browsed to a new site)?
No, but that would be fairly easy to configure - put the IoT devices on their own VLAN with dedicated DNS server. My household is small and the list of new domains visited is manageable and interesting to inspect by hand. It's definitely more of a hobby than a scalable solution, I must warn.
