# VPC Overview

* VPC lets you provision a **logically isolated section of AWS where you can launch AWS resources** in a virtual network that you define.<br>

* **Custom VPCs let you create your own VPC and configure it as you need**.<br>

* **VPC is Regional**.

* VPC **Subnet is attached to an Availability Zone** - Subnet can span only a single Availability Zone.<br>

* Because a VPC is private, you **can only have the following IP addresses:**

  * **10.0.0.0 to 10.255.255.255**\
    **172.16.0.0 to 172.31.255.255**\
    **192.168.0.0 to 192.168.255.255**

* VPC **CIDR should not overlap** with your other networks.
