Lab 3 1 ARP Observation - mathewyanez/tech-journal GitHub Wiki

In this lab I used commands to view the ARP cache, ping computers and view and analyze how the ARP requests and Responses would take place and update the cache.

Commands:

==arp -a== : Displays all connections my computer had made previously and has stored in ARP table.

==arp -d== : Deletes the ARP cache on local computer.

==Ping== : sends a request to confirm a connection to another computer with ICMP packet, should receive one back if works.

In this lab a VM while recommended was not required, and viewing the computers on the network when pinging one at times firewalls would prevent the pings from going through. ARP broadcast different from ICMP.

Default Gateway: 192.168.1.250

Deliverables 1, and 2:

ARP broadcast source and destination MAC address.

The Reply:

For Deliverable 3 the whether it is the ARP request or reply, it is simply responding to and confirming that it received the message from the other IP address/Computer. It is responding, my IP address is at this MAC address. It asks all the computes who this IP belongs to, it than responds back that that address is at said MAC address.

Deliverable 4:

Deliverable 5 Drawing:

Deliverable 6: I would send a request to my Default gateway, and from there the router would do the rest, I would never see the MAC address on googles end. To see the MAC address on googles end you would have to do some very illegal things.
