Updated on November 27, 2024

A Virtual Private Cloud (VPC) 2.0 network enables a secure and isolated private networking interface on your instance for communication with other instances on the same network. You can attach multiple VPC 2.0 networks to enable communication between an instance and other nodes attached to the same network.

Follow this guide to attach VPC 2.0 networks on a Vultr Cloud GPU instance using the Vultr Customer Portal, API, or CLI.

  2. Click your target instance to open its management page.

    View active instance subscriptions

  3. Navigate to the Settings tab.

    Navigate to the Settings Tab

  4. Click VPC 2.0 on the left navigation menu.

  1. Send a GET request to the List Instances endpoint and note the target instance's ID in your output.

    console 
    $ curl "https://api.vultr.com/v2/instances" \
  -X GET \
  -H "Authorization: Bearer ${VULTR_API_KEY}"

  2. Send a GET request to the List Instance VPC 2.0 Networks endpoint to list all VPC 2.0 networks in your Vultr account and note the target VPC 2.0 network's ID.

    console 
    $ curl "https://api.vultr.com/v2/instances/{instance-id}/vpc2" \
  -X GET \
  -H "Authorization: Bearer ${VULTR_API_KEY}"

  3. Send a POST request to the Attach VPC 2.0 to Instance endpoint to attach the VPC 2.0 network to the instance.

    console 
    $ curl "https://api.vultr.com/v2/instances/{instance-id}/vpc2/attach" \
  -X POST \
  -H "Authorization: Bearer ${VULTR_API_KEY}" \
  -H "Content-Type: application/json" \
  --data '{
    "vpc_id": "<vpc-id>"
  }'

  1. List all instances available in your Vultr account and note the target instance's ID.

    console 
    $ vultr-cli instance list

  2. List all VPC 2.0 networks in your Vultr account and note the target VPC 2.0 network's ID.

    console 
    $ vultr-cli vpc2 list

  3. Attach the VPC 2.0 network to the instance.

    console 
    $ vultr-cli vpc2 nodes attach <vpc2-id> \
        --nodes="<instance-id>"
