| network_type                 | core | string     | The cluster's NetworkType can be IPv4 (the default) or DUALSTACK. The IPv4 NetworkType restricts communication between your application and the hardware security modules (HSMs) to the IPv4 protocol only. The DUALSTACK NetworkType enables communication over both IPv4 and IPv6 protocols. To use DUALSTACK, configure your virtual private cloud (VPC) and subnets to support both IPv4 and IPv6. This configuration involves adding IPv6 Classless Inter-Domain Routing (CIDR) blocks to the existing IPv4 CIDR blocks in your subnets. The NetworkType you choose affects the network addressing options for your cluster. DUALSTACK provides more flexibility by supporting both IPv4 and IPv6 communication. |
