Part B: Lab2 (2%) 1. Use different TCP/IP commands to find out the MAC address of your computer's default gateway. Please include screenshots to support your answer. And, also determine: i) The class of the IP address that is assigned to the gateway ii) And the network address for the gateway's IP address (2+1=3 Points) 2. As a network administrator, you may sometimes find that you need to track down the owner of a particular IP address. For instance, you may discover that a host of an IP address outside of your network is generating excessive amounts of traffic to your web server. To ask whoever owns this host to stop, you must contact the owner. You can use the Web site of a Regional Internet Registry (RIR) to find this information. In this part of the lab, you will use the nslookup command to find the IP address of a website. Then you will look up that IP address on https://www.arin.net. (3 Points) a. Take a website of your choice b. Now at the command prompt, type nslookup followed by a space and then the name of the website c. Some websites may have multiple IP addresses. If this is the case, use the last IP address found. d. Now find the owner of the IP address using https://www.arin.net. Please include the screenshots as well. 3. We will use the netstat command with the 's' parameter for this part of the lab. netstat -s displays statistics per protocol. (4 Points) a. type netstat -s. Record 'Segments Received' from 'TCP Statistics for IPv4' and 'Datagrams Received' from 'UDP Statistics for IPv4' [attach screenshot] b. Now play any video for two minutes on www.youtube.com c. Repeat step: 3.a [attach screenshot] d. Now, based on the results that you have found in 3(a) and 3(c), answer the following: For the video playback, which protocol (TCP/UDP) is mostly used by YouTube? Calculate the difference between the results found in 3(a) and 3(c). Part B: Lab2 (2%) 1. Use different TCP/IP commands to find out the MAC address of your computer's default gateway.
