How to Attach a VPC Network to a Vultr Cloud Compute Instance

1 min readUpdated 4 November 2026

Connect a Vultr Cloud Compute instance to an isolated private VPC network shared with other instances.

A Virtual Private Cloud (VPC) network creates a secure and isolated private networking interface to enable connections to other instances attached to the same network. You can attach multiple VPC networks to a Vultr Cloud Compute instance. Vultr recommends a maximum transmission unit (MTU) of 1450 on VPC network interfaces, because a larger MTU results in poor network performance.

Follow this guide to attach a VPC network to a Vultr Cloud Compute instance using the Vultr Console, API, CLI, or Terraform.

Warning

Attaching an instance to multiple VPC networks with overlapping IP blocks breaks network connectivity on the instance.

Navigate to Compute and click Instances.
Click your target Vultr Cloud Compute instance to open its management page.
Navigate to the Settings tab.
Click VPC Networks on the left navigation menu.
Click Enable VPC.
Click Enable VPC in the confirmation prompt to restart the instance and attach a VPC network.
Optionally, click the VPC drop-down, select another VPC network in the same location, and click Attach VPC to attach it to the instance.
