Amazon Lambda now supports IPv6 endpoints for inbound connections, allowing customers to invoke Lambda functions over IPv6. This helps customers to meet IPv6 compliance requirements, and removes the need for expensive networking equipment to handle address translation between IPv4 and IPv6.

To use this new capability, configure your applications to use Amazon Lambda’s new dual-stack endpoints which support both IPv4 and IPv6. When you make a request to a dual-stack Lambda endpoint, the endpoint resolves to an IPv6 or an IPv4 address, depending on the protocol used by your network and client.

To connect programmatically to an Amazon Web Services service, you can specify an endpoint in Amazon Web Services CLI or Amazon Web Services SDK. For more information on service endpoints, see Amazon Web Services service endpoints. To learn more about Lambda’s service endpoints, see Amazon Lambda service endpoints in Amazon Web Services documentation.

You can use Amazon Lambda’s new dual-stack endpoints for inbound connections at no additional cost. The new dual-stack endpoints are generally available in Amazon Web Services China (Beijing) Region, operated by Sinnet, and Amazon Web Services China (Ningxia) Region, operated by NWCD.
