# Create a Subnet

You can create subnets to separate the network. Instances in different subnets of the same network can communicate securely.

## Prerequisites

You can create 3 subnets in one network. After creating a subnet, you can create an instance and attach it to the subnet.

## Procedures

1. Log in to [**zenConsole**](https://console.zenlayer.com/).
2. Go to **Compute** > **Virtual Machine** > **Subnet** and click **Create Subnet**.
