I have taken note of the fact that very often the fastest of the fast DNS servers are those using DNS over TLS. When I configure my network to use those. DNSB shows it as my local router vs. as the DOT servers I have chosen. I have searched the net and configured my set up accordingly and tested to check for DNS leaks. Is the problem that I need to configure my PC for DOT directly? Is DOT a fools errand for a home user trying to use DHCP for local devices?
