To assign IPv6 addresses to server accounts, you must have root-level access and first configure IPv6 ranges through your server management panel. Before assigning dedicated IPv6 addresses, ensure IPv6 is enabled on your server and that at least one IPv4 address is configured, as IPv6-only servers are not supported due to networking requirements.
OBHost servers require proper IPv6 configuration to take advantage of modern internet protocols while maintaining backward compatibility with IPv4 systems.
Prerequisites for IPv6 Assignment
Before you can assign IPv6 addresses to accounts, you must complete these essential setup steps:
- Enable IPv6 on your server and add IPv6 ranges through the IPv6 Ranges interface in your server control panel
- Configure the server daemon to listen on IPv6 addresses by enabling the appropriate setting in your server configuration
- Ensure at least one IPv4 address is assigned to your server, as IPv6-only configurations are not supported
Important: Do not configure a shared IPv6 address that exists within an IPv6 range. The system will automatically block any shared IPv6 addresses that fall within configured ranges.
How to Assign IPv6 Addresses
Once your server meets the prerequisites, follow these steps to assign IPv6 addresses:
- Access the IPv6 assignment interface in your server management panel
- Select the account you want to configure from the account selection menu
- Choose either a dedicated IPv6 address or assign the shared IPv6 address
- Save your changes to apply the new IPv6 configuration
You can filter accounts by username or primary domain using the search function to quickly locate specific accounts. To assign IPv6 addresses to multiple accounts simultaneously, use the select all option.
Understanding Dedicated vs Shared IPv6 Addresses
You have two options when assigning IPv6 addresses:
- Dedicated IPv6 addresses: Assign unique IPv6 addresses from your configured ranges to individual accounts. This provides each account with its own distinct IPv6 identity.
- Shared IPv6 address: Configure a single shared IPv6 address that multiple accounts can use. This must be set up in your basic server configuration before assignment.
Important Warnings and Considerations
Keep these critical points in mind when working with IPv6 assignments:
- When you assign IPv6 ranges through this interface, the system will erase any IPv6 addresses previously assigned to selected accounts through other methods
- Your web server must be properly configured to handle IPv6 traffic. If you see warnings about server compilation, you may need to rebuild your web server configuration
- Always test IPv6 connectivity after making changes to ensure proper functionality
Viewing Account IPv6 Information
After assigning IPv6 addresses, you can review the configuration for any account:
- Select the desired account from the account menu
- The interface displays the assigned IPv6 address and related configuration details
- You can modify or remove IPv6 assignments as needed
The account information section shows all currently assigned IPv6 addresses and allows you to make adjustments to the configuration.
Frequently Asked Questions
Can I run a server with only IPv6 addresses and no IPv4?
No, you cannot run an IPv6-only server. Due to networking requirements, you must have at least one IPv4 address configured on your server, even if you plan to use IPv6 for most services.
What happens to existing IPv6 addresses when I assign new ones?
When you use the IPv6 assignment interface, the system erases any IPv6 addresses that were previously assigned to the selected accounts through other methods. Make sure to document your current configuration before making changes.
Do I need to configure anything special for shared IPv6 addresses?
Yes, you must configure a shared IPv6 address in your basic server setup before you can assign it to accounts. The shared IPv6 address must not fall within any of your configured IPv6 ranges, or the system will block it.
How do I know if IPv6 is properly enabled on my server?
Check that IPv6 ranges have been added to your server through the IPv6 Ranges interface. If no ranges are configured, the interface will display a message indicating that no IPv6 ranges have been added. Also verify that your server daemon is configured to listen on IPv6 addresses in your server settings.
