Announcing ClassicLink DNS Support
We are pleased to announce ClassicLink DNS Support for Virtual Private Cloud (VPC). This feature enables support for DNS resolution of public hostnames to private IP addresses when queried over ClassicLink. A public DNS hostname of an instance in a VPC will resolve to private IP address when queried from a linked EC2-Classic instance. Similarly, a public DNS hostname of a linked EC2-Classic instance will resolve to private IP address when queried from an instance in the VPC. Additionally, you can now access private hosted zones associated with your VPC from a linked EC2-Classic instance. ClassicLink DNS support makes it easier for EC2-Classic instances to communicate with VPC resources using public DNS hostnames.
For more information see ‘Enable ClassicLink DNS Support’. You can learn more about ClassicLink, here.
