IP addresses

Purpose

• gain familiarity with IP addresses and what they mean.
• practice using search engines to find information on the Web.

Preparation

Use a search engine to find information about IP addresses and to find at least one Web page which will tell you the IP address of any machine from which you retrieve the page. NOTE: Your answers will be graded on whether they are right or not, so it is important to find a reliable Web site. Better yet, find two or three and compare the answers you get from them.

The Tasks

1. From a compuuter on campus, use one of the sites you found above to determine your IP address. What is it?
2. Try another computer on campus. Do you get the same address?
3. Try an off-campus computer, home, work, or the public library. What computer did you use? What is the reported IP address of that computer?
4. Find a page which defines the difference between Class A, Class B, Class C, Class D, and Class E networks. Which do we have at B-W? How do you know?
5. Based on your decision about the class of our BW domain, how many different host addresses can we have on campus? Explain your answer.
