I need help with my subnets for my IPv6 CIDR

Question

I am migrating to use IPv6 addressing with CIDR.  I created a new IPv6 CIDR and moved on to editing my three subnets. Here is what my three IPv4 CIDRs look like

![Enter image description here](/media/postImages/original/IMpgN9fGQUQUq0Y-JSBBMcEA)

The new IPv6 CIDR was created from the AWS pool is: 2600:1f16:c4e:9900::/56

I am confused by what my three subnets should look like using this CIDR.  Can you help me with this?

Answer

After you have associated an IPv6 prefix to a VPC, you can begin to assign one /64 IPv6 prefix to each subnet.
