# Create a VPC

Create a VPC, a private network in your project with an address range you choose. Resources you place on it
reach each other over private addresses instead of the public internet.

## Before you begin

You need a TIR project in Delhi or Chennai and a role with Create permission on VPCs. Create
the VPC in the project and region of the machines that will use it.

Choose the range before you start. It is fixed once the VPC exists, so size it for where you expect to be. For help
with the size, see [VPC address ranges](/tir/tir-vpc/concepts/vpc-address-ranges/).

## Open the form

In TIR, open your project. In the side menu, under **PLATFORM SERVICES**, select **Networking**, then **VPC**. The page
lists the VPCs of the project and region. Select **Create VPC**.

## Name the VPC

In **VPC Name**, keep the suggested name or type your own. A name has up to 50 characters, starts with a letter, ends
with a letter or digit, and uses only letters, digits, hyphens, and underscores in between. Each name must be unique
within the project and region, and `default` is reserved in any mix of upper and lower case.

## Set the range

In **IPv4 CIDR Block**, type a private range, for example `192.168.50.0/24`. **Available ranges** above the field list
what you can use. The prefix must be between /16 and /28. As you type, the form checks the range and
shows "Available." or the reason it is refused. Write the range from its first address, as in `172.16.231.0/24` rather
than `172.16.231.5/24`.

## Create it

Once the range passes the check, **Create VPC** becomes available. Select it.

## When the VPC is ready

The new VPC is at the top of the list with **Status** **Creating**, and it turns **Active** by itself once it is
ready. Select the VPC to see its **Overview**: **Name**, **Status**, **CIDR**, **Network Mask**, and **Created By**.

Once the VPC is **Active**, put a VM on a CPU plan on it: choose the VPC when you
[create the VM](/tir/tir-vm/how-to/create-a-vm/), or [attach it to a VM](/tir/tir-vm/how-to/attach-a-vpc-to-a-vm/)
you already have. For help with a message about the range or name, see
[Troubleshooting VPC](/tir/tir-vpc/troubleshooting/tir-vpc/).
