Introducing dual-stack and IPv6-only support for Amazon Route 53 Resolver Endpoints
Blog
This article introduces dual-stack and IPv6-only support for Amazon Route 53 Resolver Endpoints, which allows forwarding DNS traffic to and resolving DNS traffic from on-premises DNS servers with IPv6 addresses.
Specifically, the article covers:
- An overview of Amazon Route 53 Resolver Endpoints and their role in resolving DNS queries across hybrid networks
- Prerequisites for enabling IPv6 connectivity, such as setting up Amazon VPC with dual-stack or IPv6-only subnets, configuring AWS Transit Gateway, AWS Direct Connect, and AWS Site-to-Site VPN
- A solution overview with three use cases:
- Centralized Route 53 Resolver Inbound Endpoint deployment using Private Hosted Zone to VPC association
- Centralized Route 53 Resolver Outbound Endpoint to on-premises resources (IPv6) using AWS RAM for cross-account resolver rule sharing
- Centralized Route 53 Resolver Outbound Endpoint (IPv6-only subnets) to on-premises resources (IPv4) using AWS RAM for resolver rule sharing and NAT64 translation
- Detailed explanations and diagrams for each use case, illustrating the DNS query flow and required configurations
