Amazon DocumentDB now supports Internet Protocol Version 6 (IPv6)

Amazon DocumentDB now offers customers the option to use Internet Protocol version 6 (IPv6) addresses on new and existing clusters. Customers moving to IPv6 can simplify their network stack by running their databases on a dual-stack network that supports both IPv4 and IPv6. IPv6 increases the number of available addresses and customers no longer need to manage overlapping IPv4 address spaces in their VPCs (Virtual Private Cloud). Customers can standardize their applications on the new version of Internet Protocol by moving to dual-stack mode (supporting both IPv4 and IPv6) with a few clicks in the AWS Management Console or directly using the AWS CLI. Amazon DocumentDB is a fully managed, native JSON database that makes it simple and cost-effective to operate critical document workloads at virtually any scale without managing infrastructure. Amazon DocumentDB support for IPv6 is generally available on version 4.0 and 5.0 in AWS Regions listed in [Dual-stack mode Region and version availability](https://docs.aws.amazon.com/documentdb/latest/developerguide/vpc-clusters.html#dual-stack-availability). To learn more about configuring your environment for IPv6, please refer to [Amazon VPC and Amazon DocumentDB](https://docs.aws.amazon.com/documentdb/latest/developerguide/vpc-docdb.html).
