Conditional Forwarding

Conditional forwarding is a way to stitch discontinuous DNS architectures together by forwarding queries to specific resolvers and overriding the normal process of recursive lookups. In Route 53, this is accomplished through a combination of endpoints to route query traffic and forwarding rules, which tell Route 53 where to send query traffic for external destinations. Each of these concepts will be covered in the following sections.

Route 53 Endpoints

To facilitate routing DNS traffic between Route 53 private hosted zones (PHZs) and on-premises networks, you create endpoints. Endpoints are groupings of elastic network interfaces in your VPCs that attach to Route 53 Resolver. There are two types of endpoints – inbound endpoints and outbound endpoints:

  • Inbound endpoints allow on-premises DNS resolvers to resolve DNS names for PHZs. The on-premises resolvers forward queries to Route 53 Resolver via these inbound endpoints.
  • Outbound endpoints...
