Specific IPv6 assignment (subdomains/nameservers)
When assigning IPs to accounts, only the main domain is assigned an IPv6 address, and this address is meted out by WHM from the available pool. The address is then added to the configuration for the network device and the IP is then routable.
However, when one wishes to assign an IPv6 to a subdomain or nameserver, there is no option to have WHM draw an address from the assigned IPv6 range for those allocations. With the breadth of the IPv6 address space, it would be counterintuitive to assign an IP for the nameservers that is already assigned to a different domain.
Please add an option to configure and reserve a specific IP from the IPv6 range for manual assignment.
