In this lab we used Wireshark again, this time in our workstation computers not our VMs, to analyze the responses we got from a computer on our network and a computer outside of the network. I didn't really learn any new commands in this lab. We used the same ones we have been using. Originally a problem my partner and I ran into in the partner step was that I was only seeing my traffic. However we figured out that she had typed in my IP address wrong so that's why I didn't have any of her traffic on my Wireshark capture. I believe I understand ARP. It's how computers get the MAC addresses for other computers. They need these because the NIC won't take in information unless it's addressed with he MAC address instead of the IP address. So computers use ARP to find the Mac addresses for their destination. If it's in the network they get a response back from the computer they are looking for. If it's outside of the network they get the MAC address of the default gateway since that's who they communicate with. I understand how to capture and look though network traffic. I learned in SEC-110 and I understand how to find the information I'm looking for on a basic level.
