AWS Elastic Disaster Recovery previously required IPv4 connectivity but has since added support for IPv6 in both data replication and management plane interactions. This allows customers operating in IPv6-only or dual-stack networks to configure AWS DRS without relying on IPv4 addresses.
The update facilitates disaster recovery in network environments with limited or no IPv4 availability and helps organizations meet network modernization needs. Existing replication configurations default to IPv4 unless explicitly changed to IPv6. Availability covers all regions supporting AWS DRS and EC2 IPv6 capabilities.
