I was using Wireshark to capture network traffic on my laptop's wireless network adapter. I suddenly noticed that my router is sending ARP requests to my phone. I am wondering why this would be captured on my laptop's network interface. Why is my laptop capturing ARP requests sent to my phone? Wouldn't that have to do with communication between my router and phone ?

    This is not really a question about information security but about basic network protocols. In short: An ARP request is sent when the sender does not know which MAC (OSI layer 2) a specific IP address (OSI layer 3) has. To find the layer 2 addressing (MAC) the sender asks all systems in the network (broadcast) in the hope that one will respond that it has the specific IP address. – Steffen Ullrich Feb 10 at 19:37
