Amazon Route 53 Resolver endpoints now support DNS-over-HTTPS (DoH) with Server Name Indication (SNI) validation

News



The article announces the support for Server Name Indication (SNI) validation with DNS-over-HTTPS (DoH) on Amazon Route 53 Resolver endpoints. This allows specifying the target server hostname for DNS query requests from outbound endpoints to DoH servers that require SNI for TLS validation.

Specifically, the article covers:

  • DoH on Route 53 Resolver endpoints encrypts DNS queries for improved privacy
  • With SNI support, you can specify the hostname for TLS handshakes from endpoints to DoH servers
  • SNI validation helps meet regulatory compliance like US CISA Protective DNS requirements
  • The feature is available in all AWS Regions where Route 53 is available, including GovCloud
  • You can get started using the AWS Console or Route 53 API
