# Default VPC Overview

* A default VPC is **suitable for getting started quickly**, and for launching public instances such as a blog or simple website.<br>
* If you want to **have a more specific VPC tailored to your requirements, it is recommended to use a Custom VPC** (nondefault VPC).<br>
* You can **only have 1 default VPC per region**.<br>
* **Each VPC subnet is in a different Availability Zone** and **together, they span across all the Availability Zones in the region**.<br>
* The **CIDR Range is always the same (172.31.0.0/16)**.
