Hello fellow Squid users, can you please help? I was wondering about this for years, I have a massive block list with DoH servers. Do you really need to block DoH if you want Squid to use a specific dns? Let’s say you are using a dns over tls, to Google or cloudflare and your system sometimes wants the DoH one.one.one.one is blocking that url really needed? My list is so big it is like playing wackamole with DoH. If I block it I see all the url requests if not I see IP addresses sometimes in the get requests. I must have a ACL with thousands and thousands of DoH servers in it. 

What is recommended with sites that want DoH however clients must use Squid per firewall ACLs?
