What Is My IP Address? Find Your Public & Private IP - Free Tool

Your IP address is like your computer's digital address on the internet. It's a unique identifier that allows devices to communicate with each other. This guide explains what IP addresses are, the difference between public and private IPs, and provides a free tool to instantly find yours.   

What is an IP Address?

An IP address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions:   

•  Host or Network Interface Identification: It identifies a specific device on a network.   
• Location Addressing: It indicates the device's location on the network.   

There are two main versions of IP addresses:   

• IPv4: Uses a 32-bit numerical address (e.g., 192.168.1.1).   
• IPv6: Uses a 128-bit alphanumeric address (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 was developed to address the limitations of IPv4 as the number of internet-connected devices grew.   

Public vs. Private IP Addresses

• Public IP Address: This is the IP address that's visible to the outside world. It's assigned to your network by your internet service provider (ISP). Websites and other online services use your public IP address to communicate with your network.   
• Private IP Address: This is the IP address used within your local network (e.g., your home or office network). Devices on the same network use private IP addresses to communicate with each other. Common private IP address ranges include: 
  •  10.0.0.0 – 10.255.255.255   
  •  172.16.0.0 – 172.31.255.255   
  •  192.168.0.0 – 192.168.255.255   
•    

Your router acts as a translator between your public and private IP addresses using a process called Network Address Translation (NAT).

• macOS/Linux: Open Terminal and type ifconfig (or ip a on some Linux distributions). Look for "inet" or "inet addr" for your IP address.

Why Do IP Addresses Matter?

• Network Communication: They're essential for devices to communicate on the internet and local networks.
• Geolocation: Your public IP address can be used to approximate your geographic location.   
• Website Analytics: Websites track IP addresses for analytics purposes, such as understanding visitor demographics.   
• Security: IP addresses can be used for security purposes, such as blocking malicious traffic.
