AWS Storage Gateway now supports IPv6

[AWS Storage Gateway](https://aws.amazon.com/storagegateway/) announces Internet Protocol version 6 (IPv6) support for AWS Storage Gateway endpoints, APIs, and gateway appliance interfaces. This enhancement enables both IPv6 and IPv4 access to our new dual-stack endpoints. The existing AWS Storage Gateway endpoints supporting IPv4 only will remain available for backwards compatibility. AWS Storage Gateway provides on-premises access to data stored in AWS storage. With this launch, customers can standardize their applications and workflows for managing their AWS Storage Gateway resources on IPv6 while maintaining backward compatibility with IPv4 clients. By using the new dual-stack capabilities in the Storage Gateway appliances, service endpoints, and APIs, customers can transition from IPv4 to IPv6 gradually without needed to switch all their networking at once. AWS Storage Gateway support for IPv6 is available in all [AWS Regions where the service is offered](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/).
