D7800 router sending DNS query for domain “.” 15 times per second

Router firmware is V1.0.1.56

 

I have setup a local Pihole DNS server and pointed my router to it for DNS lookups. There have been 620,000 lookups since I set it up yesterday evening! The Pihole log file is full of lines like these:

 The netgear router 192.168.0.1 is sending 15 DNS lookups per second for the domain "."

 

 How do I get a fix from Netgear for this? The community seems to be the only way I can raise the issue?

I idea what the router is doing. Does not seem normal. I might do a reset and reconfigure.

 

I run Pi-Hole as well, but I also have it acting as the DHCP server. Doing that you get individual lookups in the log by device and gives the site being contacted.

Thanks Bill. Sounds possible. Will hold out for fix though because lot of work entering all the reservations in pi-hole DHCP screen
