MemoryDB and IPV6

You can create new dual stack and ipv6-only clusters with both Valkey and Redis OSS engines, by providing subnet groups with dual stack and ipv6-only subnets. You cannot change the network type for an existing cluster.

With this functionality you can:

  • Create ipv4-only and dual stack clusters on dual stack subnets.

  • Create ipv6-only clusters on ipv6-only subnets.

  • Create new subnet groups to support ipv4-only, dual stack, and ipv6-only subnets.

  • Modify existing subnet groups to include additional subnets from the underlying VPC.

  • Modify existing subnets in subnet groups

    • Add IPv6 only subnets to subnet groups configured for IPv6

    • Add IPv4 or dual stack subnets to subnet groups configured for IPv4 and dual stack support

  • Discover all the nodes in the cluster with ipv4 OR ipv6 addresses, through engine discovery commands for dual stack and ipv6 clusters. These discovery commands include redis_info, redis_cluster, and similar.

  • Discover the ipv4 and ipv6 addresses of all the nodes in the cluster, through DNS discovery commands for dual stack and ipv6 clusters.
