Sometimes we need to add new CIDR range, or increase number of available IP addresses in our VPC. If you are working with AWS VPC, and you face this kind of problem, no worries, AWS is giving very simple option to make you happy. Some time ago it was impossible to add new CIDR to the VPC.

Today you can add new CIDR to existing VPC in a few clicks (or commands).

You need to do it in exactly the same as always, this time you set the CIDR for those subnets with 10.100.0.0/24 and 10.100.1.0/24 ranges.
