    On the IPv6 ranges of WHm and in the IPv6 ranges documentation (11.52), you always give the example of /64 for Ipv6 CIDR.

    IPv6 Ranges - Documentation - cPanel Documentation

    I think it is too much because only ISP get this type of huge ipv6 range.

    /64 means 18446744073709551616 hosts !
    from x:x:x:x:0:0:0:0 to x:x:x:x:ffff:ffff:ffff:ffff:

    I think that most of web hosting companies only get a /112 from their ISP meaning x:x:x:x:x:x:x:0000 to x:x:x:x:x:x:x:ffff

    Also, using a /64 people may get confused between the Cidr for the network to reach the gateway and the allocated Ipv6 range they get. Then, i guess they will enter /64 in the Ipv6 range field in Cpanel and they will get "invalid Ipv6 range".

    Thanks for your input. We find that many web hosting providers in North America are indeed giving /64 to hosting customers (meaning to individual servers).

    I agree that moving from IPv4 to IPv6 can be quite confusing.
