IPv6 adding range error "Invalid IPv6 range"

[odytil]

Hi, I have been given from my VPS provider the IP address 2a02:c200:0000:0010:0002:0002:0961:0001/112.

I am trying to add it to the WHM/cPanel but I finally get the error "Invalid IPv6 range". If I put it as my provider gave it to me, I get the error "Must follow IPv6 syntax". If i give it with /119 I get the error "Invalid IPv6 range".

How can I add the IPv6 address on my VPS / WHM? What am I doing wrong?

Can anybody help?

did they actually give you 65,536 IP addresses
Probably not

I think and believe that they gave me. Because I have ordered also a VPS with WINDOWS SERVER and in that VPS I have IPv4 and IPv6 addresses together with no problem. The issue is that I can't add the IPv6 address they gave me in the WHM. Should I have to do any "preparations" before adding the IPv6 in the WHM?

Add a smaller range EG 2a02:c200:0:10:2:2:961:1/128 or 2a02:c200:0:10:2:2:961:1/124

adding a /112 does not work you might want to verify with what IP's they actually assigned you

The following third-party tool provides the start and end IPv6 address for an IPv6 address range using CIDR notation.

Try using the following range and let us know if it works successfully for you:

2a02:c200:0:10:2:2:961:0/112

Thank you.
