This feature allows users with root access to assign
an IPv6 address to a specific account. IPv6 addresses that were assigned
without this feature will be erased for the selected users when you
enable IPv6 with this feature. Hold shift and click on an account name
to select or deselect multiple accounts. Click the blue asterisk to
select all accounts.
You have not configured a shared IPv6 address. To do
this, use the Basic cPanel & WHM Setup
