Amazon Route 53 VPC Resolver
Resolve Domain Name System (DNS) queries in hybrid and VPC environments
How it works
Amazon Route 53 VPC Resolver provides a robust toolset for DNS query resolution across AWS, the internet, and on-premises networks with secure control over your Amazon VPC DNS. Queries that are forwarded to Route 53 VPC Resolver are evaluated through configured forwarding rules and through system rules.
If the query name matches a forwarding rule, the Route 53 VPC Resolver uses a Resolver Outbound Endpoint to forward the query to on-premises DNS servers. If the query name matches a system rule, the Route 53 VPC Resolver will forward the query to be answered based on Route 53 private hosted zone records, the local VPC domain names for Amazon Elastic Compute Cloud (EC2) instances, or lookups against public name servers on the internet.
Benefits
Allow AWS services to resolve DNS queries made by your VPCs and hybrid networks (over Resolver endpoints)
Manage DNS query forwarding for hybrid networks using Resolver endpoints
Secure DNS queries from exfiltration attacks using Route 53 Resolver DNS Firewall
Debug, troubleshoot, and monitor DNS traffic with Resolver Query Logging to gain visibility into your DNS queries
Use cases
Resolver handles DNS queries locally within your Amazon VPCs and AWS Outposts and enables you to create endpoints with conditional forwarding rules to resolve DNS namespaces between on-premises data centers and Amazon VPCs.
Define firewall rules using Route 53 Resolver DNS Firewall to inspect and block DNS queries using custom and predefined domain name lists. Enhance security and privacy for DNS queries for hybrid networks by ending and receiving using DNS-over-HTTPS (DoH).
Manage resolution of internal DNS resources hostnames with Amazon Route 53 Private DNS.
