# How to Manage IPv4 on a Vultr Cloud GPU Instance

A public IPv4 network is available and attached to your Vultr Cloud Compute instance after deployment unless disabled by default. You can attach multiple IPv4 addresses on an instance to enable connections on the main public networking interface.

Follow this guide to manage the IPv4 information on a Vultr Cloud GPU instance using the Vultr Console, API, or CLI.

=== "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 **IPv4** on the left navigation menu to view your instance's public IPv4 network information.
    1. Click **Add Another IPv4 Address** to attach another public IP address to the instance.
    1. Check the confirmation prompt and click **Add IPv4 Address** to attach the new public IP address and restart your instance.
    1. Click the default IPv4 reverse DNS value and replace it with your values to enable reverse DNS on your instance.

=== "Vultr API"

    1. Send a `GET` request to the [**List Instances** endpoint](https://www.vultr.com/api/#tag/instances/operation/list-instances) 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}"
        ```

    1. Send a `GET` request to the [**List Instance IPV4 Information** endpoint](https://www.vultr.com/api/#tag/instances/operation/get-instance-ipv4) to view the instance's IPv4 information.

        ```console
        $ curl "https://api.vultr.com/v2/instances/{instance-id}/ipv4" \
          -X GET \
          -H "Authorization: Bearer ${VULTR_API_KEY}"
        ```

    1. Send a `POST` request to the [**Create IPv4** endpoint](https://www.vultr.com/api/#tag/instances/operation/create-instance-ipv4) to attach a new IPv4 address on the instance. 

        ```console
        $ curl "https://api.vultr.com/v2/instances/{instance-id}/ipv4" \
          -X POST \
          -H "Authorization: Bearer ${VULTR_API_KEY}" \
          -H "Content-Type: application/json" \
          --data '{
            "reboot" : true
          }'
        ```

    1. Send a `POST` request to the [**Create Instance Reverse IPv4** endpoint](https://www.vultr.com/api/#tag/instances/operation/create-instance-reverse-ipv4) to enable reverse DNS on the instance.

        ```console
        $ curl "https://api.vultr.com/v2/instances/{instance-id}/ipv4/reverse" \
          -X POST \
          -H "Authorization: Bearer ${VULTR_API_KEY}" \
          -H "Content-Type: application/json" \
          --data '{
            "ip" : "<ipv4-address>",
            "reverse" : "<domain>"
          }'
        ```

=== "Vultr CLI"

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

        ```console
        $ vultr-cli instance list
        ```

    1. List the instance's IPv4 address information.

        ```console
        $ vultr-cli instance ipv4 list <instance-id>
        ```

    1. Create a new public IPv4 address and attach it to the instance. 

        ```console
        $ vultr-cli instance ipv4 create <instance-id> --reboot
        ```

    1. Create a new IPv4 reverse DNS entry on the instance.

        ```console
        $ vultr-cli instance reverse-dns set-ipv4 <instance-id> --entry <domain> --ip <ipv4-address>
        ```
