1 min readUpdated 26 May 2026

A guide explaining how to configure IPv6 addressing on your Vultr Optimized Cloud Compute instance.

IPv6 is available but a public address is not automatically assigned to a Vultr Optimized 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 network information on a Vultr Optimized Cloud Compute instance using the Vultr Console, API, CLI, or Terraform.

Navigate to Products and click Compute.
Click your target Vultr Optimized 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.
