How can I find the computer's IP address by using the Command prompt?
I am currently engaged in q a task related to working as an IT support specialist for a mid-sized company. One of the employees has been experiencing issues related to the network and needs assistance. To diagnose the problem, I need to find the IP address of the computer of the employee. I have decided to use the command prompt to obtain this Information. Describe the steps should I take to find the IP address of the employee’s computer by using the command prompt.
In the context of CS, here are comprehensive steps given:-
Open command prompt
Firstly, you should press Win+R to open the run dialog box. Then try to type “cmd” and press “Enter” to open the command prompt.
Using the “ipconfig” CommandIn the command prompt windows, you should try to use the following command and press enter
“ipconfig”This command would help in displaying the current TCP/IP network configuration values of the machine.
Analysis of the output
The “ipconfig” command would help in producing a list of all network adapters on the computer along with their IP address and other relevant information.
You should try to look for the section corresponding to the active network adapter, which would be under a heading such as “Ethernet adapter”.
Here is an example given:-

Import java.util.*;
