You can use Route 53 to configure split-view DNS, also known as split-horizon DNS.

If you want to maintain internal and external versions of the same website or application (for example, for testing changes before you make them public), you can configure public and private hosted zones to return different internal and external IP addresses for the same domain name. Just create a public hosted zone and a private hosted zone that have the same domain name, and create the same subdomains in both hosted zones.
