I am using Firefox and would like to know why https://1.0.0.1/dns-query using the IP address 1.0.0.1 works for Firefox instead of the default domain “https://mozilla.cloudflare-dns.com/dns-query” Which does not work. The domain mozilla.cloudflare-dns.com which resolves to IP 104.16.248.249 and 104.16.249.249 do not work even if I make the domain “https://104.16.248.249/dns-query”.
