IPWhat Is My Public IP Address vs Private IP Address?
When people ask "what is my IP address," they are usually asking for two very different things without realizing it. Your device actually has multiple IP addresses at once — a public one and a private one. Understanding the difference between them is essential for troubleshooting networks, setting up servers, or just understanding how the internet works.
WHAT IS A PUBLIC IP ADDRESS?
Your public IP address is the address that the entire internet can see. It is assigned to you by your Internet Service Provider (ISP) — companies like Jio, Airtel, BSNL, Comcast, or BT. Think of it as your home's street address: it is unique on the global internet, and it is how websites, apps, and servers identify where to send data back to you.
Every device on your home network — your laptop, phone, tablet, and smart TV — all share the same public IP address. When you visit a website, that website only sees one IP: your public one.

WHAT IS A PRIVATE IP ADDRESS?
Your private IP address is the address your router assigns to each individual device inside your home or office network. These addresses are not visible to the outside internet — they only work within your local network.
Common private IP address ranges:
- 192.168.x.x (most home routers)
- 10.x.x.x (businesses and larger networks)
- 172.16.x.x to 172.31.x.x (less common)
For example, your laptop might have the private IP 192.168.1.5, your phone might be 192.168.1.6, and your smart TV 192.168.1.7 — but all three devices appear to the outside world as one single public IP.
HOW DOES THE CONVERSION WORK?
Your router performs a process called Network Address Translation (NAT). Here is how it works step by step:
- You open a website on your laptop (private IP: 192.168.1.5)
- Your router receives the request and replaces your private IP with your public IP
- The request goes out to the internet using your public IP
- The website sends data back to your public IP
- Your router receives it and forwards it to your laptop's private IP
This process happens in milliseconds and is completely invisible to you. NAT is also a basic security feature — devices outside your network cannot directly contact your private IP.
HOW TO FIND YOUR PUBLIC IP ADDRESS
Method 1 — Online Tool (Easiest):
Visit iptrackertools.com/what-is-my-ip and your public IP appears instantly.
Method 2 — Google Search:
Type "what is my ip" into Google. It shows your public IP at the top of results.
Method 3 — Command Line:
On Windows, open Command Prompt and type: curl ifconfig.me
On Mac/Linux, open Terminal and type: curl ifconfig.me
HOW TO FIND YOUR PRIVATE IP ADDRESS
On Windows:
Press Win + R, type cmd, press Enter, then type: ipconfig
Look for "IPv4 Address" under your active adapter.
On Mac:
Apple Menu >; System Preferences >; Network >; select connection >; your IP is listed.
On iPhone:
Settings >; Wi-Fi >; tap (i) next to your network >; IP Address
On Android:
Settings >; About Phone >; Status >; IP Address
WHY DOES THIS DIFFERENCE MATTER?
Understanding the difference matters in several situations:
Port Forwarding: If you want to host a game server or run a website from home, you need to set up port forwarding on your router using your private IP, so external traffic coming to your public IP gets routed to the right device.
Remote Access: If you use remote desktop software, you need to know whether you are connecting via public or private IP, as they require different configurations.
Network Troubleshooting: Many connectivity problems come from confusion between public and private IPs. Knowing which one is relevant helps you diagnose issues faster.
VPN Usage: When you connect to a VPN, your public IP changes to the VPN server's IP. Your private IP stays the same.
IS YOUR PUBLIC IP ADDRESS DANGEROUS TO SHARE?
Your public IP address reveals your approximate city and ISP, but not your name or exact location. Sharing it in most casual contexts is fine. However, in adversarial situations — like online gaming where someone might try to DDoS you — it is wise to keep it private. A VPN is the easiest way to mask your public IP from others.
CONCLUSION
Your public IP is your internet-facing address visible to the world. Your private IP is your internal address used only within your home network. Both are necessary for internet connectivity, but they serve very different roles. Use iptrackertools.com to check your public IP anytime, and use your device settings to check your private IP.
Frequently Asked Questions
What is a public IP address?
A public IP address is the unique address assigned by your ISP that is visible to the internet and used by websites to communicate with your network.
What is a private IP address?
A private IP address is assigned by your router to devices within your local network and is not visible to the outside internet.
What is the main difference between public and private IP?
A public IP is used on the internet and shared by all devices in your network, while a private IP is used internally to identify individual devices.
Can two devices have the same public IP address?
Yes, multiple devices in the same network share one public IP address assigned by the ISP.
Can two devices have the same private IP address?
No, each device within the same network must have a unique private IP address to avoid conflicts.
What is NAT in networking?
NAT (Network Address Translation) is a process where your router converts private IP addresses into a public IP so devices can communicate with the internet.
How do I check my public IP address?
You can check your public IP using online tools like iptrackertools.com or by searching "what is my ip" on Google.
How do I find my private IP address?
You can find your private IP in your device settings or by using commands like ipconfig on Windows or checking network settings on mobile devices.
Does a VPN change my IP address?
Yes, a VPN changes your public IP address to the VPN server’s IP, but your private IP remains the same.
Is my public IP address permanent?
Not usually. Most ISPs assign dynamic public IPs that can change periodically unless you have a static IP.
Is it safe to share my public IP address?
Generally yes, but avoid sharing it in risky situations as it can expose your approximate location and be misused.
Can someone access my device using my public IP?
Not directly in most cases, because routers and NAT block unsolicited incoming connections unless ports are opened.
What are common private IP ranges?
Common ranges include 192.168.x.x, 10.x.x.x, and 172.16.x.x to 172.31.x.x.
Why do all my devices show the same public IP?
Because your router connects all devices to the internet using a single public IP provided by your ISP.
Do I need both public and private IP addresses?
Yes, both are essential. Public IP connects your network to the internet, while private IP manages communication within your network.
