Create Route 53 Inbound Endpoints

Create Route 53 Inbound Endpoints

To enable your on-premise DNS system to query Route 53 Resolver for specific DNS zones (such as Private Zones) hosted on Route 53, you need to set up a Route 53 Inbound Endpoint. This Inbound Endpoint serves as a link for other services to request domain name resolution from Route 53. When you create an Inbound Endpoint, AWS generates an elastic network interface (ENI) in each specified availability zone (AZ) to handle incoming DNS queries.
