Windows 10: What do you think about this ARP attack log in my router?

Hi! I looked today into the log section of my router, and I found some strange listing about some sort of ARP attack. I didn't know who are these source IP addresses come from. They are unknown to me. Should I take any action? Thanks.

If you want to do some investigation first step is to note down known hosts on same segment.

Then run:
Code:

And make sure all IP entries match correct MAC entry that you gathered.

You could write a simple script that would compare ARP cache output against it's own list of dynamically mapped entries and report any IP\MAC discrepancies.

And if that happens, you could launch your own ARP discovery against bad entry to learn more about target host.
You could also simply block specific hosts in router or in case of wireless change WI-FI password.
