DNS ipv6 domain configuration

Hello,

I was looking for some tutorial about ipv6 and domain configuration.

I have google and looking here. I have found.
https://community.centminmod.com/threads/cloudflare-ipv6-compatibility-pseudo-ipv4.17066/

but some VPS provuders like netcup gave

ipv6
7a07:3000:2:82b2::/64

and gateway
fe80::1

I was googling but i did not found the answer.
I am sorry for silly questions but I am a beginner in this area.

I have found only
Zusätzliche IP Adresse konfigurieren – netcup Wiki


May you advise how to configure few domains e.g Wordpress blogs with centminmode?


7a07:3000:2:82b2::/64 << is it 64 ip ?


I would be very grateful for a solution or even further reading.
