Document Content and Description Below

Part One 1. Identify the ARP request from 130.203.151.88 looking for the address of 130.203.151.1. What is the MAC Address of 130.203.151.88? Note: you need to dig into the data to get the full 48-... bit (hex) MAC address. Hint – We want you to provide the hex MAC address, so it doesn’t start with “Dell”. Provide a screenshot. Sender MAC address: 78:2b:cb:8a:13:a3 2. Identify the next ARP response. What is the MAC Address of 130.203.151.1? Note: you need to dig into the data to get the full 48-bit (hex) MAC address. Hint – it doesn’t start with “Cisco”. Provide a screenshot. Sender MAC address: (00:22:55:3a:9d:c0) 3. Identify an ARP request from 130.203.151.1 looking for the address of some other node. What is the destination MAC address of this request? Why do you send this request in this fashion? Provide a screenshot. Dst MAC (ff:ff:ff:ff:ff:ff), doesn’t know which machine belongs to the address, so it sends out a broadcast message. 4. Assuming the other host is turned on and responds, explain why you don’t see the response in this packet capture. The packet capture is a broadcast 5. What role do you think that 130.203.151.1 plays in this network? Explain the reasoning behind your conclusion. It is the network gateway because it is the router sending out broadcast addresses. Part Two 6. What is the 48-bit Ethernet address of the computer that made the request? Provide one screenshot to cover questions 6 and 7. Source: (78:2b:cb:8a:13:a3) [Show More]
