Comment (by anonymous):
What you're missing is [https://en.wikipedia.org/wiki/Broadcast_address
broadcast addresses]. Generally the all-zero and all-ones IP addresses
are reserved and both can potentially handled as broadcast. So, when you
ping 2001:910:1105::/48, this is being treated as a broadcast and
'''all''' devices on the network may potentially respond; since the
router's own IP address 2001:910:1105:ff00:: is on the subnet, it receives
the broadcast and responds. If you had at least one more device you would
see ''multiple'' responses for every ping packet sent out.
