Question 1 - Information about the block

a) How many addresses are available in the block allocated to the company, including all special addresses?
b) What is the network address of the block?
c) What is the direct broadcast address of the block?

Question 2- Allocating subnets from the block

Create five contiguous subnets from the given block beginning with the first address of the block, as follows:
a) The first subnet with 1024 addresses
b) A second subnet with 512 addresses
c) A third subnet with 256 addresses
d) Two more subnets with 128 addresses each

For each subnet, show its prefix in CIDR format, its subnet address, and its direct broadcast address. Organize your data clearly in a table.

Question 3 - Network Tools (Windows)

Often the best way to gain an initial familiarity with network tools is to simply use them at a basic level, exploring and looking up information as you go. Some common tools you can explore include Wireshark, Ipconfig, Tracert, Netstat, Ping and Arp. All but Wireshark are included in Windows, Wireshark is free to download and install.

Explore these tools by researching online and trying them out yourself. Then answer the following questions, using your own words.

a) You have listed several devices (all turned on and working) in your home network along with their IP addresses. You decide that you want to add a column for their MAC addresses as well. From your desktop what command (tool) could you try first to get the MAC addresses? Explain the tool and its output.

b) You want to find out what IPv6 address your PC is currently configured with. What command could you use to discover this? What other information could you discover from using that command? Explain your answer.

c) Assume that your computer is configured with IP address 192.168.0.230. You ping this address and receive four successful ping replies. Does this indicate that your PC has Internet access? Explain the tool, and the reasoning for your answer.

Question 4 TCP

Study a diagram of a TCP segment header, paying special attention to the header fields, then list each field along with the value in decimal that would be in that field if you assume the following: Briefly (a few words only) explain your answer for each field.
• The segment is from an FTP client to an FTP server
• A port number of 49,500 was assigned to this segment
• There are 8 bytes of options
• The server will be instructed not to send more than 500 bytes at any one time
• The TCP checksum was calculated to equal binary zero
• The previous segment to this one was acknowledged by the server with an ack/data segment that had an acknowledgement number of 15,000 and a sequence number of 9,000
• The control flag fields indicate states of Not urgent; not first (sync request) or final (termination request) segment; no bypass of buffer queues required; and not a rest.
