I was checking the neighbor table on my router running OpenWRT 19.07.3, r11063-85e04e9f46 and found the following:

    2001:db8::ad10:a4cd dev eth1  INCOMPLETE
    2001:db8::ad10:aaf8 dev eth1  FAILED

of all the addresses in the list, only 1 is a valid host. That makes me thinking that something in my network is actively scanning 2001:db8:0:ad10::/112?

The valid host is a Proxmox server.

Any ideas anyone?

The all seeing eye sees everything...
