How to Add IPv6 Addresses on a Vultr Cloud Compute Instance

1 min readUpdated 23 October 2026

Enable IPv6 on a Vultr Cloud Compute instance, which has no public address by default, and set reverse DNS.

IPv6 is available but a public address is not automatically assigned to a Vultr Cloud Compute instance unless enabled during instance configuration. Once enabled, you can manage the instance's IPv6 network settings and configure reverse DNS for specific networking tasks.

Follow this guide to add the IPv6 information on a Vultr Cloud Compute instance using the Vultr Console, API, CLI, or Terraform.

Navigate to Products and click Compute.
Click your target Vultr Cloud Compute instance to open its management page.
Navigate to the Settings tab.
Click IPv6 on the left navigation menu.
Click Assign IPv6 Network to assign a new subnet to the instance.
Click Assign IPv6 Network Address to attach an IPv6 address to the instance.
Find the Reverse DNS section, enter your IPv6 address in the IP field, and a domain in the Reverse DNS field to enable reverse DNS.
