Case Project 9-4: Troubleshoot an IP configurationYou work at a help desk and have just received a call from an employee who says she can’t access network resources. You want the employee to view her IP address configuration. Write an e-mail to the employee explaining what command-line program to use and how she can use it to find the information you need. After following your instructions, the employee tells you that her IP address is 169.254.14.11 with the subnet mask 255.255.0.0.a. Write an e-mail to the employee explaining what command-line program to use and how she can use it to find the information you need. b. What conclusion can you make from the employee’s information about her IP address and subnet mask?

To get the IP address and other information on the workstation, type 'ipconfig' for windows or 'ifconfig' or Linux and press the return key.

The subnet mask is a class B type and 169.254.14.11 IP address shows that the workstation cannot access the DHCP server, so the IP address is not properly configured for network connection.

Explanation:

A computer network is an interconnection and intercommunication of two or more computer devices. All devices in a network must have an IP address, which can be static or dynamic from a DHCP server.

When a computer is configured to receive IP address from a DHCP server, but cannot reach the server, the IP address from the range of 169 is automatically assigned to it but still would not be able to communicate with other devices in the network.
