About This Tool

What Is an IP Address?

An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to a network that uses the Internet Protocol for communication. Think of it as a digital mailing address: just as a postal address tells the post office where to deliver a letter, an IP address tells the internet where to send data. When you visit a website, stream a video, send an email, or download a file, your device's IP address is included in every request so the destination server knows where to send the response.

IP addresses are fundamental to how the internet works. Every connected device — from your smartphone and laptop to servers in data centers and IoT devices in your home — has at least one IP address. Without IP addresses, there would be no way to route data between billions of devices across the global network.

IPv4 vs IPv6

There are two versions of IP currently in use: IPv4 and IPv6.

IPv4 is the original and most widely recognized format. It uses a 32-bit address space, written as four decimal numbers separated by dots — for example, 192.168.1.1 or 203.0.113.42. This format provides approximately 4.3 billion unique addresses. While that seemed like plenty when IPv4 was designed in the early 1980s, the explosive growth of internet-connected devices has exhausted the available IPv4 address pool.

IPv6 was developed to solve the address shortage. It uses a 128-bit address space, written as eight groups of four hexadecimal digits separated by colons — for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334. This provides approximately 3.4 x 10^38 unique addresses, enough to assign an IP to every atom on Earth's surface. IPv6 also includes built-in security features, improved routing efficiency, and simplified address configuration.

Most modern networks run in dual-stack mode, meaning both IPv4 and IPv6 are active simultaneously. Your device may have both an IPv4 and an IPv6 address, and the tool above detects both.

Public vs Private IP Addresses

IP addresses come in two categories: public and private.

A public IP address is assigned to your connection by your Internet Service Provider (ISP). It is globally unique and visible to every website, server, and service you connect to on the internet. When you use this tool, it detects and displays your public IP — the address that the outside world sees.

A private IP address is used within your local network. Common private IP ranges include 192.168.0.0/16, 10.0.0.0/8, and 172.16.0.0/12. Devices on your home or office network communicate using private IPs, and your router translates between private and public addresses using a process called Network Address Translation (NAT). Private IPs are not routable on the public internet — they are invisible to external websites and services.

When you check "What is my IP," you will see your public address. To find your private address, you would need to check your device's network settings or run a command like ipconfig on Windows or ifconfig on macOS/Linux.

How This Tool Works

The What Is My IP tool uses a server-side detection mechanism to read the source IP address of your incoming HTTP request. When your browser loads this page, your request passes through your router, ISP, and potentially a proxy or VPN before reaching our servers. The IP address attached to that request is your public IP — the one we display.

In addition to your IP address, the tool performs a reverse lookup to identify your ISP name and performs a geolocation query to determine your approximate city and region. This information comes from publicly maintained IP databases that map address ranges to ISPs and geographic regions. The entire process is automatic — no input, forms, or button clicks are needed from you.

Use Cases for Checking Your IP

Knowing your public IP address is useful in many practical scenarios:

Network troubleshooting — When diagnosing connectivity issues, confirming your public IP helps you verify that your ISP is assigning an address correctly and that your router is functioning as expected.
VPN verification — After connecting to a VPN, checking your IP confirms whether the VPN is working. If the displayed IP matches your VPN server's location instead of your real location, the VPN is masking your traffic correctly.
Geo-location testing — Marketers, developers, and QA teams use IP checks to verify how websites and services behave for users in different geographic regions.
Remote access configuration — To set up remote desktop, SSH access, or port forwarding on a home or office server, you need to know your public IP address to connect from outside the local network.
Firewall and access control — Many cloud servers and databases restrict access by IP address. Knowing your current IP lets you whitelist it for authorized access.
Privacy auditing — Checking what IP address you are broadcasting to the world helps you understand your online privacy footprint and decide whether you need additional protections like a VPN.

Privacy Considerations

Your public IP address reveals more about you than you might expect. While it does not directly expose your name or physical address, it can be used to determine your approximate geographic location, your ISP, and in some cases your organization. Websites, advertisers, and trackers use your IP to profile your location and browsing habits.

If privacy is a concern, you can mask your real IP using a Virtual Private Network (VPN), a proxy server, or the Tor browser. Each of these tools routes your traffic through an intermediary, so the destination server sees the intermediary's IP instead of yours. This tool can help you verify that your privacy tools are working by showing you the IP address you are actually presenting to the internet.

It is important to note that no tool can provide 100% anonymity. WebRTC leaks, DNS requests, and browser fingerprinting can still reveal information about you even when your IP is hidden. A comprehensive privacy approach combines IP masking with other security practices.

Privacy and Security

Your IP address is detected in real time from your HTTP request and displayed on screen only. We do not log, store, or share your IP address or any connection details. No cookies, tracking scripts, or analytics tools collect your IP information. The detection happens on our server and the data is discarded immediately after the page is rendered. Your privacy is respected throughout the process.

IP geolocation data is approximate and may not reflect your exact physical location. Your ISP may route traffic through infrastructure in a different city or region. Only your ISP can directly link your IP address to your personal account information.

AI Overview

Your public IP (Internet Protocol) address is the unique numerical identifier assigned to your internet connection by your Internet Service Provider (ISP). It functions like a return address on a letter, allowing websites and online services to send data back to your device. Every HTTP request, API call, or file download you make includes your public IP address so the responding server knows where to send the data.

Quick Answers

What is my public IP address?

Your public IP address is the unique identifier your Internet Service Provider assigns to your connection. Every website and online service you visit sees this address. This tool detects and displays it instantly.

Is my IP address visible to websites I visit?

Yes. Every website you visit can see your public IP address. It is sent with every HTTP request. Websites use it for geolocation, analytics, access control, and in some cases, tracking.

Can someone find my physical address from my IP?

No. IP geolocation can approximate your city or region, but it cannot reveal your exact street address or personal identity. Only your ISP can link your IP to your account details.

Does using a VPN change my IP?

Yes. When you connect through a VPN, websites see the VPN server's IP address instead of your real one. This tool will display the VPN server's IP, confirming the VPN is working.

Why do I have both IPv4 and IPv6 addresses?

Modern networks use dual-stack configuration, providing both IPv4 and IPv6 addresses simultaneously. IPv4 is the older standard with limited addresses, while IPv6 is the newer standard with a vast address space.

Is my IP address static or dynamic?

Most home internet connections use dynamic IP addresses assigned by the ISP via DHCP. The IP may change when your router restarts or after a certain period. Some business connections use static IPs.

Does this tool store my IP address?

No. Your IP address is detected in real time for display only. We do not log, store, or share your IP or any connection details. The data is discarded immediately after display.

Why does my IP show a different city than my actual location?

IP geolocation databases map IP ranges to approximate regions, not exact addresses. Your ISP may route your traffic through a different city, or the database may not reflect recent address reassignments.

Common Mistakes

Confusing your local/private IP address (192.168.x.x or 10.x.x.x) with your public IP address — this tool shows your public IP, not your local network address
Assuming your IP address is permanent — your ISP may assign a different IP when your router reconnects or after a power cycle
Believing that hiding your browser IP hides your IP from all services — VPNs, proxy servers, and WebRTC leaks can still reveal your real IP
Using an outdated IP lookup that returns stale data — always use a live tool like this one to get your current address
Thinking your IP address reveals your exact physical address — IP geolocation provides city-level accuracy at best, not street addresses
Forgetting to check IPv6 — many modern connections use IPv6 in addition to or instead of IPv4, and both should be verified
Not checking your IP when switching networks — your IP changes when you move from Wi-Fi to mobile data or connect to a different network

Professional Tips

Check your IP after enabling or disabling a VPN to confirm the VPN is working correctly and your real IP is hidden
Use both IPv4 and IPv6 detection to ensure your dual-stack network is configured properly and both addresses are routable
Compare your IP across multiple tools periodically to verify consistency and detect any DNS or proxy configuration issues
If you see an unexpected IP address, check your router settings and VPN configuration — it may indicate a misconfigured proxy or DNS leak
Keep a record of your usual IP ranges so you can quickly spot unauthorized access or unusual network activity
When testing firewall rules or access controls, verify the IP your target service sees matches what this tool reports

Frequently Asked Questions

Your public IP address is the unique identifier assigned to your internet connection by your ISP. Every website you visit sees this address. This tool detects and displays it instantly along with your ISP name and approximate location.

IPv4 is a 32-bit address format (e.g., 192.168.1.1) that provides about 4.3 billion unique addresses. IPv6 is a 128-bit format (e.g., 2001:0db8::1) that provides an effectively unlimited number of addresses. Both are used to identify devices on a network.

A public IP address is assigned by your ISP and is visible to the entire internet. A private IP address (e.g., 192.168.x.x) is used within your local network and is not directly accessible from the internet. Your router translates between the two using NAT.

Yes. VPNs, proxy servers, and the Tor browser can mask your real IP address. When you use a VPN, websites see the VPN server's IP instead of yours. This tool helps you verify whether your IP is truly hidden.

For most home users, yes. ISPs typically assign dynamic IP addresses via DHCP, which may change when your router restarts or after a lease period. Some users have static IPs that remain constant.

Your IP address is already visible to every website you visit. While sharing it in a trusted context is generally safe, exposing it publicly could make you a target for DDoS attacks or network scanning. Use a VPN if you want to conceal it.

IP geolocation databases map IP address ranges to approximate regions, not exact locations. Your ISP may route your traffic through a different city, or the database may be out of date. Geolocation is typically accurate to city level, not street level.

The tool uses a server-side API to read the source IP address of your incoming HTTP request. This is the same address that every web server sees when you visit a website. Detection is automatic and requires no input from you.
