Dual-stack endpoint support

Amazon Private Certificate Authority provides a dual-stack public endpoint that supports both IPv4 and IPv6 clients. A dual-stack endpoint enables clients to communicate with Amazon Private CA using either IPv4 or IPv6 addresses. Amazon Private CA for Active Directory and Amazon Private CA Connector for SCEP also support dual-stack endpoints.

The Amazon Private CA dual-stack public endpoint at https://acm-pca.your-region.api.aws supports both IPv4 and IPv6 clients. Amazon Private CA is also privately accessible over IPv4 and IPv6 from your virtual private cloud (VPC) using Amazon PrivateLink. For more information about creating private interface VPC endpoints for Amazon Private CA, see Amazon Private CA VPC endpoints (Amazon PrivateLink).
