Amazon has announced that CloudFront, AWS WAF, and Amazon S3 Transfer Acceleration have all been updated to support IPv6. The company
says: "IPv6 will be enabled by default for all newly created Amazon CloudFront web distributions starting today. For existing web distributions, you can enable IPv6 through the Amazon CloudFront console or API. ... AWS WAF also supports IPv6. If you use AWS WAF in conjunction with Amazon CloudFront, you can now update your web access control lists (WebACLs) and IP rulesets to blacklist/whitelist IPv6 address. ... Your applications can now connect to Amazon S3 Transfer Acceleration endpoints for object storage over IPv6. This release follows Amazon S3’s recently added support for IPv6 announcement." Customers will incur no additional charges for the upgrade.
