Working with Private Hosted Zones

A private hosted zone is a container that holds information about how you want to route traffic for a domain and its subdomains within one or more Amazon Virtual Private Clouds (Amazon VPCs). To begin, you create a private hosted zone and specify the Amazon VPCs that you want to associate with the hosted zone. You then create records that determine how Amazon Route 53 responds to queries for your domain and subdomains within and among your Amazon VPCs. For example, if you have a web server associated with your domain, you'll create an A record in your hosted zone so browser queries inside the VPC for are routed to your web server. For more information about records, see Working with Records. For information about the Amazon VPC requirements for using private hosted zones, see Using Private Hosted Zones in the Amazon VPC User Guide.

If you want to route traffic for your domain on the internet, you use a Route 53 public hosted zone. For more information, see Working with Public Hosted Zones.
