ARP Observation - sullivaneg/TechJournal-NET150 GitHub Wiki

In this lab we used Wireshark to capture ARP packets to better understand how ARP works between computers on the same network. One command I used was ip -s -s neigh flush all, to clear the ARP cache. The lab told us that you could also use arp -d but that didn't work for me so I just used the ip one. We also used the ping command again. We learned that if you ping anything outside of the network you are always communicating with he default gateway, whereas if you ping a computer within the network you are connecting with them directly.
