Name: Section Number:

Internet Scavenger Hunt Lab

Format: Submit a document that contains the answers to these questions. Do not leave in the directions and graphics. When you are done, you will have 20 answers and your name and section number at the top. Email this document to your lab instructor before the due date given by your lab instructor. You are being given a chance to earn 10 extra credit points which will be added on to your overall point total for the semester.

LATE PAPERS WILL NOT BE ACCEPTED FOR ANY REASON (it is extra credit)

The document you send will be one to two pages long (not 9 pages long like this document) if you follow instructions given in Blackboard.

NOTE: This is an extra credit assignment. Each student must do his/her own work, but to be clear – you must complete this assignment on your own and you may not share your answers with classmates. You cannot work on this assignment with another student and you should try to complete the assignment without asking your lab instructor for answers (again, it is extra credit!)

I hope this extra credit makes up for some missed quiz answers and/or a missed blog!

To submit your answers, you must create a Word document showing the answer for each question. Do not include the questions or instructions - just type the number of the question and your answer(s).

Send this document to your lab instructor as an attachment --

Section 1 and 3 – Chris Tolis – [email protected] 2 – Joanne Nichols – [email protected]

Be sure to mention your name and section number and the words “extra credit” in the email subject heading and your name and section number should be part of the Word document. Follow these instructions if you want the entire 10 extra credit points.

ACTIVITY:

For each of the following items, answer the following questions using an Internet search engine and provide the URL where the answers can be found.

1. Live video feed from somewhere in the world – your choice! (a permanent feed / webcam, not a temp YouTube or Facebook live stream)

http://______________________________________

2. A picture of a storm taken from outer space (link directly to the jpg or png image).

http://______________________________________

Domain Names: To answer the following questions, you will need a computer with a network connection and a command prompt. You can do this on your own computer. To get to the command prompt:a. Hold down [WINDOWS] + R to bring up the run dialog box b. Type in “cmd” (without the quotes)

Note that in Windows 7 you can type “cmd” in the search bar and then hit enterIn Window 8 you type “cmd” in the start menu or Right Click in the bottom left corner of your screen to pull up the administration menu and click on “Command Prompt”. Windows 10, type cmd in search bar next to start button.

d. Press enter. You should be at a c: > prompt. This is called the command line. You use commands instead of clicking on icons in Graphical User Interface (GUI).

Note for MAC Users: To get to the command prompt In the utilities folder (found in the applications folder) there is utility named Terminal. Double click on this, and this gets you to a command prompt. This assignment will be easier to complete using a Windows machine. The path will look something like c:\directory name >

e. You will now type at the c:\directory name> prompt, the command, nslookup 67.195.160.76, and then press enter.

Instructions for copy and paste (if using Windows 10, you will not need to right click and mark)Answers 3-7 should be full copy and paste, from the nslookup command to end of info presented on screen (just like in lab example)

1. Use cut and paste method to put in this document. 2. Right click and select mark. 3. Then left click your mouse to highlight what you wish to copy. Then right click in your homework document and paste results.

3. What is the host name or domain name for the IP 65.204.48.118 address? __________________

4. What is the host name or domain name for the IP address 5.79.86.80? __________________ 5. What is the host name or domain name for the IP address 132.170.254.11? __________________

Instead of using the IP address with nslookup, use the domain name (don’t type in www.)

6. What is the IP address of overstock.com? _________________________

7. What is the IP address of garmin.com? _______________________

Go to the following site: http://www.godaddy.com If you wanted to register a domain name, you can do a search to see what is available. There are many sites like this which help you create your own domain name and Web site. These sites are under the umbrella organization of ICANN (Internet Corporation of Assigned Names and Numbers).

List two other Web sites at which you can register a domain name.

Ping is a utility which helps in troubleshooting network communications. It actually sends four (by default) “echo” packets to a specified address to test responsiveness between two hosts. It waits for a reply. If you have lost your network connection at home and you call tech support, they will use the ping command to test if your computer is still on the network.

A. Ping howstuffworks.com and follow the procedure described below to record results. You can see an example of how to do a ping in the picture below which is a ping for www.temple.edu. For the assignment, you must ping howstuffworks.com – do not type in www. like in the below example.

To record response: 1. Use cut and paste method to put in this document. 2. Right click and select mark. 3. Then left click your mouse to highlight what you wish to copy. Then right click in this document and paste results in the space provided.4. Or you could create a separate text file by using the exact syntax in the screen shot below. The file temple.txt will be saved in the same directory in which it was created. In this case, the text file is located in my documents. You may attach that file to this assignment.

10. Record your results of pinging howstuffworks.com (don’t use www.) :

B. Here is a screen shot displaying the results after pinging www.upenn.com

When a sending computer pings to another computer, it sends typically four ICMP (Internet Control Message Protocol) echo request messages. If the connection is made, the receiving computer replies with the same number of bytes. Bytes=32 refers to the number of bytes sent, time =19 ms refers to the round trip time of packet in milliseconds, and TTL=47 refers to the time to live for each packet. TTL acts as a counter and will disappear after 47 hops. The ping statistics summarizes the information. The ping command can be very helpful if you are trying to troubleshoot a lost Internet connection (demonstrated later in this lab.)

TRACERT is also a network troubleshooting utility program which both checks the responsiveness between two hosts and traces the path the packet takes to get from one host to another. It discovers the routes or paths that the packets actually take. This is shown in Fig. 1. Note that the times shown are actually the time it takes for a packet to move from the last router to the current router and back to the last router. This is called the RTT (Round Trip Time).

Figure 1

A. At the c:\name of directory>prompt, type in the tracert planethippo.co.uk (do not use www.) To record response:

1. Use cut and paste method. 2. Right click what you wish to copy. Select mark. 3. Then left click your mouse to highlight what you wish to mouse. You may then right click in the document and paste results in this document in the space provided.4. Or you could create a separate text file by using the exact syntax in the screen shot below. The file temple.txt will be saved in the same directory in which it was created. You may attach that file to this assignment.

11. Record your response of doing a tracert of planethippo.co.uk (do not use www.)

Below are the results from tracert www.bucks.edu

Figure 2

12. Studying Figure 2 above, how many hops (really routers or networks) did the packets travel? (Hint look at far left column.

13. When an asterisk (*) appears, it usually means that there is a firewall at that router location to reject the tracert request. This prevents the public and thus hackers from seeing the networks. On Figure 2, at which hops do you see this occurring? (Hint: There are six hops where this occurs.) Can you tell what network are these routers located? Why or Why Not?

14. According to figure 2 above, through which three states do the packets going to www.bucks.edu travel?

IPCONFIG - This is one of the most useful commands in troubleshooting your network and Internet access. If you have lost Internet access, this is the first command to use. This command will help you determine if you are receiving an IP address. If your computer is not receiving an IP address, then your computer is not connected to the network and will not get Internet access. There are two ways to receive an IP address:

a. A static IP address which is assigned and is manually typed into network properties. b. A computer receives an IP address dynamically from a special server called a DHCP server which provides IP addresses when a computer boots up into its network.

You are going to type in several commands and record each response. The first command you will type at the prompt is ipconfig /all. This command will display all TCP/IP network configurations.

For Mac Users: Instead of typing ipconfig, type ifconfig (stands for interface configuration)

When you type in this command ipconfig /all from the command line, the following identifiers will appear if you have a wireless connection. At the top of the network configurations is the type of network interface card (NIC card) used in the network connection. In the example below – “Ethernet adapter Wireless Network Connection” indicated a wireless connection. Something like Figure 3 appears. (Note there maybe some variation to Figure 3)

Figure 3

Or if you might have a wired connection which would have Ethernet adapter Local Area Connection

Answer the following questions using your results of using the IPCONFIG /ALL.

Find the physical address of your computer? This is frequently referred to as your MAC address. It is a 12 digit hexadecimal number which is unique to your network interface card (NIC). You may have two MAC addresses. If you have a wired Ethernet NIC card and a wireless NIC card, you will have two different MAC addresses. Since the MAC address is unique, it is used for authentication.

Questions 15-20. Do an IPCONFIG /ALL to find your information. Find the section where your MAC address, DHCP info, IP address (v4 and v6) info, DNS server info, and default gateway info are located and take a screenshot. Paste that screenshot into your document before answering 15-20. Crop out the unnecessary portions to save space. It should look something like this:

Note: Everyone will have different answers from the above image. If necessary, Google how to take a screenshot and crop an image. Both are relatively simple and are good skills to have.

15. Your MAC address (physical address) is:

16. Is DHCP enabled?

17. What is the DHCP server IP address?

18. What is the IP address of your computer? If your computer has both an IPv4 and an IPv6 address (this should be the case on Temple computers) please list both.

19. What are the DNS server addresses?Note: The DNS servers need to translate all domain names IP addresses. Your ISP provides two DNS servers, in case one fails.

20. What is its IP Address of the default gateway?

Note: The default gateway is the first router to which your local LAN to which your computer is connected. The default gateway is literally a gateway to other networks to which your LAN is connected. The Internet consists of many millions of networks that are all connected. If you are not getting any IP address, you would use the ping command to see if your computer is communicating with the router. If it is not communicating, you will not have Internet access. You might also want to ping the DNS servers and the DHCP server to see whether your computer is communicating with all of those computers. If there is a failure of communication, you will not have Internet Access.

You have completed the assignment. Be sure the document you e-mail to your lab instructor includes your name, your section number, and a numbered list containing the answers to all 20 questions. Your document should not include the questions, explanations, or pictures found in the homework assignment. See the first page for full instructions.
