Tegan works for an ISP and has been asked to set up the IP addressing scheme for a new region of

the city they are providing with Internet service. She is provided the Class B address of

141.27.0.0/16 as a starting point and needs at least 25 subnets. What is the CIDR subnet mask,

how many networks does this allow for, and how many hosts will be available on each subnet?

2. Describe the function of private IP addresses, and list the private IP address ranges for Class A,

B, and C TCP/IP networks.

3. Alexis has arrived at work this morning, logged on to her Windows 7 machine, and found that she

has no Internet access. You respond to her network support call. All of the obvious hardware and

configuration settings check out, so you run ipconfig /all. The IP address is

169.254.113.97/16. What do you think the problem could be? What might you check next?

4. Ian is troubleshooting a network connectivity problem. He tries pinging 127.0.0.1, but the

command is unsuccessful. What might this indicate?

5. Matthew is trying to determine if Workstation A and Workstation B are on the same network or

not. Workstation A has an IP address of 172.16.33.1/20 and Workstation B has an IP address of

172.16.45.254/20. Are they on the same network?
