I am trying to learn about how ARP protocol works in LANs. So, here is the physical structure of my network:
So, when I try to ping PC3 from PC1, I expected the first packet to timeout because PC1 at first does not have the MAC address for PC3, so it should do an ARP request to get the MAC address first.
Now, when I pinged, all the packets arrived successfully!
My question is: Why is there no timeout? How did the packet arrive without knowing PC3's MAC address?
