Lab 3‐1 ‐ ARP Observation - TheWumpDump/NET-150 GitHub Wiki

This lab consisted of pinging devices after clearing the ARP cache to see how ARP works.

Critical commands:

  • arp -d - dumps ARP cache
  • arp -a - displays ARP cache
  • passwd {user} - changes password on Linux
  • ping {IP/DNS} - pings.

(Note: I am well aware I used the wrong syntax for optional inputs in commands.)

I can't see anything of note after pinging Google's DNS. this is probably due to the fact that ARP is only used to identify devices on the LAN.
