Part 1:Develop the IPv4 Addressing Scheme

Total points: 20

Time: 25 minutes

Given an IP address and mask of 10.10.0.0/16 (address / mask), design an IP addressing scheme that satisfies the following requirements. Network address/mask and the number of hosts for Subnets A and B will be provided by your instructor.

Subnet	Number of Hosts
Subnet A	2300
Subnet B	120

The 0^th subnet is used. No subnet calculators may be used. All work must be shown on the other side of this page.

Subnet A
Specification		Student Input	Points
Number of bits in the subnet		12	(7 points)
IP mask (binary)	00001010.00001010.00000000.00000001
New IP mask (decimal)		255.255.240.0
Maximum number of usable subnets (including the 0th subnet)		4096
Number of usable hosts per subnet		4094
IP Subnet		10.10.0.1/20
First IP Host address		10.10.0.1
Last IP Host address		10.10.15.255

Subnet B
Specification		Student Input	Points
Number of bits in the subnet			(7 points)
IP mask (binary)
New IP mask (decimal)
Maximum number of usable subnets (including the 0th subnet)
Number of usable hosts per subnet
IP Subnet
First IP Host address
Last IP Host address

Host computers will use the first IP address in the subnet. The network router will use the LAST network host address. The switch will use the second to the last network host address.

Write down the IP address information for each device:

Device	IP address	Subnet Mask	Gateway	Points
PC-A				(6 points)
R1-G0/0			N/A
R1-G0/1			N/A
S1			N/A
PC-B

Before proceeding, verify your IP addresses with the instructor.

Part 3:Test and Verify IPv4 End-to-End Connectivity

Total points: 8

Time: 10 minutes

Step 1:Verify network connectivity.

Use the ping command to test connectivity between all network devices.

Note: If pings to host computers fail, temporarily disable the computer firewall and retest. To disable a Windows 7 firewall, select Start > Control Panel > System and Security > Windows Firewall > Turn Windows Firewall on or off, select Turn off Windows Firewall, and click OK.

Use the following table to methodically verify connectivity with each network device. Take corrective action to establish connectivity if a test fails:

From	To	IP Address	Ping Results	Points
PC-A	R1, G0/0			(1 point)
PC-A	R1, G0/1			(1 point)
PC-A	S1 VLAN 1			(1 point)
PC-A	PC-B			(1 point)
PC-B	R1, G0/1			(1 point)
PC-B	R1, G0/0			(1 point)
PC-B	S1 VLAN 1			(1 point)

In addition to the ping command, what other command is useful in displaying network delay and breaks in the path to the destination? (1 point)
