Buster: How to disable IPv6 but keep local fd68:

[Solderbro]

Hello,

like to disable the routeable IPv6 but it should keep the fd68 local link for my home net. There are many of many explanations in the internet, to do it with the sysctl command. But there are only help to disable IPv6 at all or switch it all on.

Would like to see this

enp4s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.xx.xx netmask 255.255.255.0 broadcast 192.168.xx.xxx
inet6 fe80::230c:7bc:dd36:fcd6 prefixlen 64 scopeid 0x20<link>
inet6 fd68:1405:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx prefixlen 64 scopeid 0x0<global>
inet6 fd68:1405:xxxx:xxxx:xxx prefixlen 128 scopeid 0x0<global>

But no routeable IPv6 here. So all clients in my local net can address the raspi with IPv4 and IPv6.
