How to Find a Loopback Address?
In this article, we will find the Loopback address for both the famous OS:
- Windows Operating System
- Linux Operating System
Let’s explore the steps to find the Loopback Address in both OS.
1. Windows Operating System
Step 1: Open the Command Prompt in Windows OS by pressing the Windows Key+R and typing “cmd” into the input box. This will open the Command Prompt. We can also open the Windows Poweshell. Both prompts can be used to get the Loopback address of our machine.
Step 2: Once the Command Prompt is opened, enter the below command in the prompt, to see all the IP configuration information for all network interfaces on our computer.
netsh interface ipv4 show address
Step 3: Now, look for the network interface mainly named “Loopback Pseudo-Interface 1“. In this “Loopback Pseudo-Interface 1“, we will find the IPv4 address, which is 127.0.0.1. This is the Loopback Address of our Windows system. You can also see the below screenshot.
2. Linux Operating System
Step 1: Open the terminal in Linux OS by finding the terminal application in the “Utilities” or “System” folder. You can also use the below shortcut to launch the terminal
CTRL+ALT+T
Step 2: Once the terminal is launched successfully, we need to execute the below command in the terminal to display all the network configurations for all network interfaces on our Linux machine,
ifconfig or ip addr
Step 3: Look for the network interface names as “lo” or “lo0” Under this specified interface, we will find the inet address, which is 127.0.0.1. This is the loopback address of our Linux machine.
How to Find a Loopback Address?
In a Computer Network, the Loopback Address is an important address that is used for testing and troubleshooting the network connectivity on the local machine. this address provides a path for a computer system to transfer network packets to itself without involving any external networks. Loopback address allows developers and system administrators to check network functionality, test applications, and diagnose network issues in a controlled environment. In this article, we will see the information on the Loopback Address and Steps for finding the Loopback address in Windows and Linux OS systems.
