Reduced Ad Blocking Capability The main reason you should Pi-hole as your only DNS server is that you will see increased performance in the blocking of ads. If you have two DNS servers (Pi-hole and something else), your network clients may not always query Pi-hole for name resolution. If a query happens to be answered from a non-Pi-hole DNS server, your block lists will not apply (since that DNS server doesn't know about them). All Queries Need To Go Through Pi-hole First Since other DNS se…

I have a Hitron hitgn cgnv4 router and DHCP disabled in it.
Dhcp I have included in PiHole and he is the only dns.

Check your clients and make sure they only have Pi-hole as the sole DNS server.
