I have a /48 net and use a /64 net for the network with the servers.
I have an adresse like “1234:5678:9abc:def0:1111:2222:3333:4444/64” for the server.
so the prefix should be “1234:5678:9abc:def0” , right?
I also configured IPv6 gateway and DNS as “1234:5678:9abc:def0::1” (Adresse of the router)
in my Setup the router is the main DNS.
I configured the eth0 like that, but it shows now
“1234:4567:89ab:cd00:1111:2222:3333:4444**/7**”
but it should be
“1234:4567:89ab:cd00:1111:2222:3333:4444**/64**”
So IPv6 is not working. With SLAAC sometimes it works for a while, but then not and then it’s fine again for a while …
Where is my error?
