Tech Journal

In this lab found the gateways MAC address, we found the reply packets from the gateway, we found the message in the ARP request and reply, I pinged my neighbors system and analyzed the ARP packets from it and I pinged googles public DNS server and analyzed those packets. Some commands I used was arp -d which cleared the ARP cache and I used the ping command which shows if a specific address is online or not. I did not run into any problems during this lab.
