Starting today, Amazon Route 53 Resolver supports using the DNS over HTTPS (DoH) protocol for both inbound and outbound Resolver endpoints. As the name suggests, DoH supports HTTP or HTTP/2 over TLS to encrypt the data exchanged for Domain Name System (DNS) resolutions.
Using TLS encryption, DoH increases privacy and security by preventing eavesdropping and manipulation of DNS data as it is exchanged between a DoH client and the DoH-based DNS resolver.
