Things To Remember To Create A CIDR Block
- It can be sized between /16 and /28 and must not overlap with any existing CIDR block that’s associated with VPC.
- The first four and last IP addresses are not available for use and once defined, the size of existing CIDR block cannot be resized.
- It is recommended that CIDR blocks from RFC 1918 ranges are used and ensure that you have enough networks and hosts.
- Bigger CIDR blocks offer flexibility and smaller CIDR blocks work for small use cases, learning etc.
