Amazon OpenSearch Service now offers customers the option to use Internet Protocol version 6 (IPv6) addresses for their new and existing domains. Customers moving to IPv6 can simplify their network stack by running their OpenSearch Service domains on a network that supports both IPv4 and IPv6.

The continued growth of the internet is exhausting available Internet Protocol version 4 (IPv4) addresses. IPv6 increases the number of available addresses by several orders of magnitude and customers no longer need to manage overlapping address spaces in their VPCs. Customers can standardize their applications on the new version of Internet Protocol by moving their OpenSearch Service domains to IPv6 using the management console or APIs.

Support for IPv6 on OpenSearch Service is available on Amazon OpenSearch Service domains in all Amazon Web Services regions where Amazon OpenSearch service is available, including the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD. Please refer to the Region Table for more information about Amazon OpenSearch Service.

To learn more about configuring your environment for IPv6, please refer to the IPv6 User Guide.
