Homework 1 – Introduction to Networking
The goal of this assignment is for you to become familiar with some basic aspects of computer networking, starting with your own home network. If you don’t have or have access to your home network equipment, please see the instructor to discuss alternatives.
The primary interface in networking is the personal computer (PC). The PCs used in most organizations can run Microsoft Windows, Apple MacOS, and/or Linux. Most managers today have at least a basic knowledge and understanding of multiple operating systems. We will primarily be using the Microsoft Windows operating system for this class. As we’ll see in class, host systems ...view middle of the document...
Then click on Properties. Select Internet Protocol Version 4 (TCP/IPv4), and click Properties. Under the General tab, you should see your IP settings that pertain to obtaining an IP address from your ISP and also where you will be directed for DNS queries. View, but do change, the items that appear or are grayed out on the panels. Don’t worry if you don’t understand all the parameters, we’ll get to them later. Close all the panels when you are finished.
Step 2: Now that you’ve seen how your PC is configured to be setup on the network, we’ll try to use some tools to verify it. You will be accessing these tools using the command line interface, just like we did in class. To get to the command line, click on the Start button and type Run (in the ‘Search programs and files’ box). Type either cmd and hit OK or command and then OK. Type the command ipconfig/all and hit Enter. This will give you your IP address, your physical address (your Ethernet address), the IP addresses of your organization’s or ISP’s DNS hosts, and other information. Please provide a screenshot (see mine below as an example) in addition to providing the following information:
a) What is your computer’s IP address?
b) What is its Ethernet address?
________ C0-33-5E-E3-CE-FF ________________
c) What are the IP addresses of your DNS hosts?
_________________ 192.168.1.1 ______________________
d) What is the IP address of your default router (gateway)?
____________________ 192.168.1.1 ___________________
e) What is the IP address of your DHCP server?
_________________________ 192.168.1.1 ______________
f) When you get a dynamic IP address, you are given a lease time specifying how long you may use it. What is the starting time and ending time of your lease? _____________ Wednesday, September 9, 2015 12:24:01 AM

Step 3: Most of the experiments with the PC will require that the network interface card (NIC) in the computer be active. In order for this to occur, the PC must see a network device on the other end of its cable or wireless antenna. In a typical wireless home network setup, this other network device is a wireless router/access point. In a wired network setup, the PC’s NIC will have a wired (Ethernet) connection to a router. Attempt to access the router in your home network. This is where you may need to consult the device’s user manual. Usually this connection is made via a webpage, by entering an IP address such as 192.168.1.1. The user is then...
