Starting today, you can enable DNS-over-HTTPS (DoH) on Amazon Route 53 Resolver endpoints to encrypt DNS queries that pass through the endpoints and improve privacy by minimizing the visibility of the information exchanged through the queries. DoH is a protocol that protects DNS traffic by passing the queries through an encrypted HTTPS session. DoH can help enhance privacy by protecting DNS queries from eavesdropping and manipulation from unauthorized users.
