Troubleshooting IP address overlapping

Think of a scenario--you have already set up a VPC with instances inside it with, say, 172.0.x.x/16 CIDR and you've realized that the client who is going to connect also has the same CIDR block. So, wisely choose the IP address ranges for your VPC to avoid conflict with another network that you might connect to.

Getting ready

You will need access to modify the VPC.

How to do it...

The only option is to create a new VPC and migrate resources into the new one. Please follow the steps given in Chapter 2, Building Your Own Custom VPC, to create a new VPC.

There's more...

You can create multiple VPCs with the same CIDR blocks. These VPCs will act as an individual network, but if you need to do peering between two VPCs, then it will create an issue. As you can't modify a VPC CIDR block, the only solution for this issue is to create another VPC that doesn't overlap with your peering VPC.
