Hello everyone,
So from my understanding ARP should broadcast, then tables should be updated, and then until an arp table timeout there should be no more need for constant ARP request from say the router to the same host.
When I run wireshark I notice non-broadcast constant arp traffic from my router to my computer. Maybe 20 request in 10 minutes. Its from the router MAC directly to the computers MAC. Why could this be?

You guys are way over my head in networking, but I truly enjoyed your “chatter” and learned a lot about the nuances of networking. THANK YOU!
