Hi JuergenAuer,
I still not understand how to setup a shared IPv6 at WHM/ IP Functions / IPv6 Ranges
The server give me 2607:5300:120:25a::/64, I think I have to setup a shared Ipv6 then assigning to all the domain,
2607:5300:120:25a:0000:0000:0000:0000 what is correct go change the 0000:0000:0000:0000
Thanks
Jun
