Part -1:

Select one of the following questions. Post your answer and comments to the weekly discussion board.

Your answer should be well thought out (showing that you have engaged in some critical thinking about the subject matter) and be at the very least, 2 substantial paragraphs in content. Be sure to cite your sources. Failure to do so will result in a zero grade for the assignment.

1. Define the term subnet mask. What do the bits in the mask whose values are binary 0 tell you about the corresponding IP address(es)? Include an example illustrate your answer.

2. How many IP address could be assigned in each subnet of 220.8.7.0, assuming that a mask of 255.255.255.240 is used? If the same (static) mask is used for all subnets, how many subnets are there?

3. What does the acronym CIDR stand for? What is the original purpose of CIDR? Include an example illustrate your answer?

4. Name the three classes of unicast IP addresses and list their default masks, respectively. How many of each type could be assigned to companies and organizations by the NIC?

Worksheet on Subnetting

Type in your name, your answers and save the document. Submit the file to your instructor by attaching to this assignment.

You are given the network address 199.44.2.0 by your Internet Service Provider (ISP). You decide NOT to subnet. You need to assign IP addresses to the hosts on your LAN using the network address from your ISP. Answer the following questions:

What is the network address?

What is the default subnet mask?

What is the broadcast address?

How many hosts can you have on this network?

You are given the network address 210.45.1.0 and the subnet mask 255.255.255.224. You need to assign IP addresses to the hosts on your LAN using the network address from your ISP.

Answer the following questions:

Look at the subnet mask. The default subnet mask is 255.255.255.0, but you are using 255.255.255.224. How many bits did you "borrow" from the host portion in order to create subnets?

How many subnetworks can you create?

How many hosts can you have on each subnet?

What is the network address of the first subnet?

What is the broadcast address of the first subnet?

What is the first valid IP address for a host on the first subnet?

What is the last valid IP address for a host on the first subnet?

Please put answers with question and please used the submitted paper I sent you.
