The pi-hole link did say:Find the LAN option and then the DNS, delete the settings and they should default to your ISP ones.(Or set them to 8.8.8.8 or 1.1.1.1)
Or if you do wish to use PiHole, set the second DNS to 1.1.1.1 or similar and it should/may/may not work when you disconnect it.
This seems to suggest that the secondary DNS address (which doesn't adblock) may be used for normal operation (perhaps load balancing) rather than only after an absolute failure.Define Pi-hole's IP address as the only DNS entry in the router
Rationale
Only is italicized here for a reason: Pi-hole needs to be the only DNS server because it intercepts queries and decides whether or not they should be blocked. If you have other DNS servers configured, you may be sent to the correct domain, bypassing Pi-hole completely.
I'd imagine that the behaviour may be dependent on the router and devices on the network.
