# How to Manage IPv6 on a Vultr Bare Metal Instance

A public IPv6 network is available and attached to your Vultr Cloud Compute instance after deployment unless disabled by default. You can manage the IPv6 address information on an instance and enable reverse DNS on the public networking interface.

Follow this guide to manage the IPv6 information on a Vultr Bare Metal instance using the Vultr Console, API, CLI, or Terraform.

=== "Vultr Console"

    1. Navigate to **Products** and click **Compute**.
    1. Click your target instance to open its management page.
    1. Navigate to the **Settings** tab.
    1. Click **IPv6** on the left navigation menu to view your instance's public IPv6 network information.
    1. Enter your **IPv6** address in the **IP** field and a domain in the **Reverse DNS** field to enable reverse DNS on your instance.

=== "Vultr API"

    1. Send a `GET` request to the [**List Bare Metal Instances** endpoint](https://www.vultr.com/api/#tag/baremetal/operation/list-baremetals) and note the target instance's ID in your output.

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

    1. Send a `GET` request to the [**Bare Metal IPv6 Addresses** endpoint](https://www.vultr.com/api/#tag/baremetal/operation/get-ipv6-baremetal) to view the instance's IPv6 information. 

        ```console
        $ curl "https://api.vultr.com/v2/bare-metals/{baremetal-id}/ipv6" \
          -X GET \
          -H "Authorization: Bearer ${VULTR_API_KEY}"
        ```

=== "Vultr CLI"

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

        ```console
        $ vultr-cli bare-metal list
        ```

    1. List the instance's IPv6 network information.

        ```console
        $ vultr-cli bare-metal ipv6 <instance-id> 
        ```

=== "Terraform"

    Terraform can enable or disable IPv6 for a Bare Metal instance at creation time. Managing existing IPv6 addresses or reverse DNS records after deployment is not supported directly in Terraform and must be done through the Vultr Console, API, or CLI.

    1. Open your Terraform configuration for the existing Bare Metal instance.

    1. Enable IPv6 on the instance and (optionally) set reverse DNS.

        ```terraform
        # Enable IPv6 on the instance
        resource "vultr_bare_metal_server" "bm1" {
            # ...existing fields (region, plan, os_id, label, etc.)
            enable_ipv6 = true
        }

        # Optional: set reverse DNS for the instance's primary IPv6
        # (v6 address is known after the instance exists)
        resource "vultr_reverse_ipv6" "bm1_ptr" {
            ip      = vultr_bare_metal_server.bm1.v6_main_ip
            reverse = "host.example.com."
        }
        ```

    1. Apply the configuration and observe the following output:

        ```
        Apply complete! Resources: 0 added, 1 changed, 0 destroyed.
        ```
