OK thanks for the clearup. But it's still strange that I get so many responses to addresses that doesn't exist on my network.
My prefix is the same since over a year. So I stay with that to hide what is not needed to show :)
What prefix do those addresses have? If it's your assigned prefix, then those devices likely exist on your network somewhere. Privacy addresses were mentioned above. These addresses use random numbers for the suffix and you get a new one every day. After a week they expire. This is in addition to the consistent address (often MAC based). So, each device could have up to 8 global addresses.
As for hiding your prefix, you do understand that each /64 contains 18.4 billion, billion addresses, which means it would be somewhat difficult for anyone to find a working address in that space. That address space is more than 4 billion times the entire IPv4 address space.
No they're not inside my Prefix. But they are in the same format as the WAN address. I captures my WAN traffic and there is nothing going out from my network to those destinations from where I get replies. Maybe something at my ISP is misconfigured?

Run packet capture on DNS to see if there's any pattern to this. If you're seeing DNS replies back to your network, then something on your network is causing them.

There are coming back but there are no going out. Even the hosts I‘ve never heared.
