Previously limited to IPv4 or dual-stack instances, Lightsail CDN now accepts IPv6-only instances as content origins, allowing cost-effective IPv6 deployments to serve content with low latency globally. This facilitates applications running on IPv6-only infrastructure to reach all end users, including those on IPv4-only networks.

This enhancement supports multiple origin types—instances, containers, buckets, load balancers—and is available in 16 AWS Regions. It helps customers adopt IPv6 infrastructure while maintaining broad accessibility through Lightsail's CDN service.
