ISM4220, ISM6225 Lab Assignment 2. TCP/IP Command DELIVERABLE Electronic file: 4220_yourname_lab_TCPIP Command.doc Submit your file(s) through Canvas before the due date. Late submission penalty will be applied. Project 1: Using the ‘ipconfig’ Command The TCP/IP command used to test communication over IP to another host via sending out an echo request is ping. Ping Verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. The receipt of corresponding Echo Reply messages are displayed, along with round-trip times. Ping is the primary TCP/IP command used to troubleshoot connectivity, reachability, and name resolution. 1. First obtain the TCP/IP configuration of a computer by opening Command Prompt, and then typing ‘ipconfig.’ 2. This time, type ‘ipconfig /all’ 3. Fill out the following blanks by finding the information about a network you are using. Physical address (MAC address): EC-2E-98-51-5B-23 that's the address embedded in your network card, analogous to your VIN on your car. IP address: 10.13.229.141 the IP address is changeable, unlike the MAC address. Subnet Mask address: 255.255.2240 the subnet mask number tells your computer whether it is located on a subnetwork, a part of a larger network. Default Gateway: 10.13.224.5 That's the computer or router that connect to the rest of the world, outside your subnet or LAN. IP address of the DHCP server: 131.91.129.19 That's the computer that issues IP addresses to any computer that is powered up. When was the lease for the IP address obtained: Monday, September 4, 2023 2:49:51 AM When will the lease expire: Thursday September 7, 2023 5:15:44 PM For Mac Users, how to open Terminal on Mac. Instead of Command Prompt, you need to run Terminal on your Mac laptop for this project. The Terminal app is in the Utilities folder in Applications. To open it, open your Finder, and then Applications folder, then open Utilities and double-click on Terminal. Project 2: Using the ‘ping’ Command Copyright © 2020.

ISM4220, ISM6225 1. Type ‘ipconfig.’ From the display of the ipconfig command, ensure that the network adapter for the TCP/IP configuration you are testing is not in a Media disconnected state. 2. At the command prompt, ping the loopback address by typing ‘ping yahoo.com.’ What is IP address of www.yahoo.com ? Please find the IP address from the result of Ping command. Take a screenshot of result and paste it here. 3. You can use ping to test both the computer name and the IP address of the computer. If pinging the IP address is successful, but pinging the computer name is not, you might have a name resolution problem. In this case, ensure that the computer name you are specifying can be resolved through the local Hosts file, by using Domain Name System (DNS) queries, or through NetBIOS name resolution techniques. 4. Ping the IP address of www.yahoo.com , the answer of Q1. (ex. Ping 192.111.1.1). Take a screenshot of result and paste it here. Copyright © 2020.

If the ping command fails, verify that the remote host IP address is correct, that the remote host is operational, and that all of the gateways (routers) between this computer and the remote host are operational.
