Amazon S3 now supports the IPv6 protocol, so applications can connect to Amazon S3 for object storage over IPv6. You can meet IPv6 compliance requirements, more easily integrate with existing IPv6-based on-premises applications, and remove the need for expensive networking equipment to handle the address translation between IPv4 and IPv6. You can also now utilize the existing source address filtering features in IAM policies and bucket policies with IPv6 addresses, expanding your options to secure applications interacting with Amazon S3.
