Cloudshark ARP and Ethernet

Document Content and Description Below

Cloudshark ARP and Ethernet 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 screen shot. 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 screen shot. 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 1 sent this request in this fashion? Provide a screen shot. 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 screen shot to cover questions 6 and 7. Source: (78:2b:cb:8a:13:a3) What is the 48-bit destination address in the Ethernet frame? What node does this MAC address correspond to? (Hint: the answer is not the web server). Destination: (00:22:55:3a:9d:c0); 208.86.224.90 Next, answer the following questions based on the contents of the Ethernet frame containing the first byte of the HTTP response message. This will be the packet with the beginning of the text file in it. You should be able to see the text of Shakespeare’s MacBeth in the packet in the bottom window. 8. What is the value of the Ethernet source address? What device has this as its Ethernet address? Provide one screen shot to cover questions 8 and 9. Src: (00:22:55:3a:9d:c0), Cisco router [Show More]
