IPv6 should now be possible: https://aws.amazon.com/de/blogs/aws/now-available-ipv6-support-for-amazon-s3/ The Java library was updated to 1.11.26 a few minutes ago and released on GitHub. It should also be available in Maven pretty soon, including dual stack capabilities: https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-s3/src/main/java/com/amazonaws/services/s3/internal/DualstackEndpointBuilder.java

It is on Maven Central now. https://aws.amazon.com/releasenotes/9387767230430923 https://docs.aws.amazon.com/AmazonS3/latest/dev/ipv6-access.html There seem to be some restrictions when using EC2, perhaps @moxie0 could tell if this would work.

As my internet provider regularly has ipv4 outages, solving this issue would increase the connectivity of signal for me. ipv6 works much more stable at my internet provider.

Keep up the good work. Thanks!
