| Homework 13General Comments- Problem from the book are taken from the Chapter Review Problems sections.
- For full credit, provide context for each problem,
show all calculations, and explain your work/answers.
-
Numbers and/or algebra by themselves are not enough.
-
You will lose a significant amount of credit if you do not show enough work/context for your answers.
-
Homework assignments must be very neatly written or typeset (e.g. using Word or OpenOffice).
DetailsDo the following exercises from pages 194-195 of your textbook (182-183 in full book) and the ones listed below.
| Problem | Points | Comments

| | 34 | 4 | The problem gives a single URL. It is too long so it is displayed on two lines.
| | 1 below | 4 | Show all of the relevant calculations.
| | 2 below | 4 | This is not asking about network layers.
| | 3 below | 3 | Show your calculations for all three IP addresses, and explain your reasoning for each being on or not on the network.

- The subnet mask on FerzleCorp's network is 255.255.224.0.
Given this, how many IP addresses are available on the their domain?
Explain how you arrived at your answer.
(Hint: What is the 32-bit string representation
of the subnet mask, and what does that have to do with anything?)
- Suppose you try to access the KnowHope home page using the URL
http://www.hope.edu/knowhope, and get a message from your web browser
that the server cannot be contacted. You happen to know that the IP
address for www.hope.edu is 208.67.222.222, so you try
http://208.67.222.222/knowhope, and to your surprise, it works.
Clearly there is a problem somewhere on the network.
Where is the problem? Explain your answer.
-
The base network address for computers at Despair University is 198.110.96.0,
and the subnet mask is 255.255.240.0.
Given this, which of the following IPs addresses are on Despair University's network?
Justify your answers.
- 198.110.98.147
- 198.110.112.45
- 198.121.98.6
