How to Manage IPv4 on a Vultr Cloud GPU Instance

1 min readUpdated 4 November 2026

Attach another public IPv4 address, which restarts the instance, and set reverse DNS on a Vultr Cloud GPU instance.

Vultr assigns a public IPv4 address to the instance at deployment unless you disable it. You can attach multiple IPv4 addresses to 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.

Navigate to Compute and click Instances.
Click your target Cloud GPU instance to open its management page.
Navigate to the Settings tab.
Click IPv4 on the left navigation menu to view the instance's public IPv4 network information.
Click Add Another IPv4 Address to attach an additional public IP address to the instance.
Select Yes, add and restart this server in the confirmation prompt and click Add IPv4 Address to attach the new public IP address and restart the instance.
Click the default IPv4 reverse DNS value and replace it with a custom value.
Click the Update Reverse DNS icon to enable reverse DNS on the instance.
