How to Find the IP Address of a Computer: A Comprehensive Guide

Introduction

An Internet Protocol (IP) address is a unique identifier assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two primary functions: host or network interface identification and location addressing. Knowing the IP address of a computer can be useful in troubleshooting network connectivity problems, as well as for security purposes. This article will provide a comprehensive guide on how to find the IP address of a computer.

Looking at Your Computer’s DHCP Table

Your computer’s Dynamic Host Configuration Protocol (DHCP) table is a list of IP addresses and other information associated with devices connected to your network. Examining this table is another way to find the IP address of a computer.

Overview of the DHCP Table

The DHCP table contains information about each device connected to the network, including its IP address, MAC address, name, and lease time. This information is stored on the computer’s hard drive and can be viewed by accessing the DHCP table.

Once you have accessed the Command Prompt, do the following:

  • Type “ipconfig /all” into the command line and press Enter.
  • Look for the “IP Address” field to see the computer’s IP address.

Conclusion

Finding the IP address of a computer can be done in several ways, including using the Command Prompt, Network Connections window, a third-party program, checking your router settings, using online tools, and looking at your computer’s DHCP table. Knowing the IP address of a computer can be useful in troubleshooting network connectivity problems and for security purposes.

In summary, to find the IP address of a computer, you can:

  • Use the Command Prompt (type “ipconfig”)
  • Use the Network Connections window (right-click on the connection and select “Status”)
  • Use a third-party program (download and install one of the programs listed above)
