First of all, the new update to include IPv6 is fantastic and it's working beautifully. It can be a little clunky at time, but compared to my previous method of manually putting IPv6 addresses into the httpd.conf file, this is MUCH better.

On the downside, however, IPv6 is not fully integrated into cPanel. Currently I cannot assign an IPv6 address to a nameserver. I can assign IPv4 addresses without issue and they show up just fine in "listassignednsips". But the other two nameservers that I've manually assigned IPv6 addresses to by editing the appropriate DNS zones show as "No IP".

The problem now is that a new domains are not adding the last two nameservers to the NS entries in the zone file. ns1 and ns2 are in there, but ns3 and ns4 are not. I'm not sure what the deal is.

Hello :)

cPanel currently only supports IPv6 for website content. We look forward to supporting IPv6 addresses on NSD, MyDNS and BIND (for DNS functionality), however that has not yet been implemented.

Have you configured four name servers under the "NameServers" section in "WHM Home » Server Configuration » Basic cPanel & WHM Setup"?

Thank you.
