Amazon OpenSearch Serverless now supports Internet Protocol Version 6 (IPv6)

We are excited to announce that Amazon OpenSearch Serverless now offers customers the option to use Internet Protocol version 6 (IPv6) addresses for the endpoint of your OpenSearch Serverless collection. Customers moving to IPv6 can simplify their network stack by enabling their OpenSearch Serverless endpoints with both IPv4 and IPv6 addresses. 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, so customers will no longer need to manage overlapping address spaces in their VPCs. Customers can also standardize their applications on the new version of Internet Protocol by moving their OpenSearch Serverless Endpoints to IPv6 only.

OpenSearch Serverless is a serverless deployment option for Amazon OpenSearch Service that makes it simple to run search and analytics workloads without the complexities of infrastructure management. OpenSearch Serverless’ compute capacity used for data ingestion, search, and query is measured in OpenSearch Compute Units (OCUs).
