How do I exclude traffic from a range of IPv6 addresses?

Hello,

there is a info and a tutorial to exclude a range of IPv4 or IPv6 adresses.

I don’t understand the mask for a range of IPv6 addresses. By IPv4 i can use wildcards. And for IPv6?

34.254.53.*
2a03:2880:11ff:e:*
2a03:2880:11ff:e:*:*:*:*

Can i use wildcards in IPv6 similar to IPv4? And what is the right notation?

With the CIDR notation it is not so simple wich suffix is the right. When i understand the CIDR right, then the suffix makes the range? What is right and what is false?

2a03:2880:11ff:e::/24
2a03:2880:11ff:e::/32
2a03:2880:11ff:e::/56
2a03:2880:11ff:e::/64
