# Get started with VPC

Create a VPC and put a CPU virtual machine on it, so the machine has a private address that other machines
on the same VPC can reach.

## Before you begin

You need a TIR project in Delhi or Chennai, and a role that lets you create VPCs and
update VMs.

## Create a VPC

1. In TIR, open your project. In the side menu, under **PLATFORM SERVICES**, select **Networking**, then
   **VPC**, then **Create VPC**.
2. Keep or change the suggested **VPC Name**.
3. In **IPv4 CIDR Block**, type a private range such as `192.168.50.0/24`. A `/24` gives 247 addresses, a
   good size for most projects. The range is fixed once the VPC exists, so leave room to grow. The form
   lists the ranges you can use and checks yours as you type.
4. Select **Create VPC**.

The VPC shows **Creating** and turns **Active** by itself when it is ready. For help choosing a range, see
[VPC address ranges](/tir/tir-vpc/concepts/vpc-address-ranges/).

## Put a VM on the VPC

When you [create a VM](/tir/tir-vm/how-to/create-a-vm/) on a CPU plan, choose the VPC under **VPC** in
**Network & Security**. For a VM you already have, use **Attach VPC** on the VM. The VM restarts to pick up
the VPC. See [Attach a VPC to a VM](/tir/tir-vm/how-to/attach-a-vpc-to-a-vm/).

## Check the private address

Once the VM is running again, it has a private address inside the VPC's range, and VMs on the same VPC
reach each other on those addresses. On the VPC list, **Available IPs** is how many addresses are still
free, out of all the VPC can hand out.

## What to do next

- Control which traffic reaches the VMs with [Security Groups](/tir/tir-security-group/).
- To give a GPU instance or an inference service a private address, reserve an IP of **Type** Private from
  a VPC in your E2E MyAccount project. See [Reserve an IP](/tir/tir-reserved-ip/how-to/reserve-an-ip-address/).
- For help with any message, see [Troubleshooting VPC](/tir/tir-vpc/troubleshooting/tir-vpc/).
