Trying to get started with IPv6, using your manual.

The server's IPv6 IP address is: 2a01:7c8:aab4:44f::1.
The range is: 2a01:7c8:aab4:44f::/64.

Going by what the documentation appears to say, I cannot use that range without first reserving the server's IP.
If I understand the documentation correctly, I need to reserve: 2a01:7c8:aab4:44f::1/64
Without the /64 bit, WHM warns "Must include / and the network portion".

But when I try to add aforementioned range, WHM says "Invalid IPv6 range".

It also seems to already list "2a01:7c8:aab4:44f::1/64" as "The system’s shared IPv6 address."
I cannot use the "Delete Range" for the above entry.

Does this perhaps mean WHM already (auto?)added the address that I added via Basic WebHost Manager Setup? If so, perhaps the documentation needs to be updated to reflect this?

Hope to get pointers of what I should do next; thanks.

Hello @Bert de Jong,

Could you open a support ticket so we can take a closer look at the system and see how IPv6 is configured? You can post the ticket number here and I'll link this thread to it.

Thank you.

I have filed a feature request instead.

The title of the idea:
The IPv6 Address Ranges page should elaborate on "Invalid IPv6 range"

The body of the idea:
The IPv6 Address Ranges page should not just react with "Invalid IPv6 range".
It should also say why it believes a provided range is invalid.
This will allow me to assess the validity of WHM's response.

Hello @Bert de Jong,

In terms of a temporary workaround, does it help if you append /128 to the end of the single IPv6 address when configuring the server's shared IPv6 address?

Thank you.
