What Is My IP

Your public IP address is shown above the moment this page loads — along with your approximate location, Internet Service Provider (ISP), and whether your connection appears to use a VPN, proxy, or Tor. An IP address is the unique number that identifies your device on a network, and understanding it helps you troubleshoot connections, protect your privacy, and verify that tools like VPNs are working. This guide explains everything your IP reveals and what each part means.

What is an IP address and why does it matter?

An IP address (Internet Protocol address) is the number that identifies your device on the internet or on a local network. It works like a return address on an envelope: when you request a web page, the server needs to know where to send the response, and your IP is that destination. Without it, two-way communication on the internet would be impossible.

Your IP also carries useful context. It can reveal your approximate location (typically city or region level, not your exact street), the ISP that connects you, and the type of connection you're on. This information is what lets websites show local content, comply with regional rules, and detect suspicious activity such as logins from unexpected countries.

What is the difference between a public and private IP address?

You actually have two kinds of IP address at once, and they serve different purposes:

• Public IP — assigned by your ISP and visible to the wider internet. This is the address this tool shows. Every device behind your router usually shares the same public IP.
• Private IP — assigned by your router to each device on your home or office network (for example, 192.168.x.x or 10.x.x.x). These are not visible on the public internet and are reused on millions of networks worldwide.

Your router performs Network Address Translation (NAT), mapping the private addresses of your devices to the single public address when they talk to the internet, and routing replies back to the correct device.

How does an IP address work on the internet?

When you go online, your ISP gives your connection a public IP address. Each time you open a page, stream a video, or send an email, networks use IP addresses to route traffic to the right place — from the service to your device and back again. Data is broken into packets, each stamped with a source and destination IP, and routers along the path read those stamps to forward the packets hop by hop until they arrive. The Domain Name System (DNS) supports this by translating human-friendly names like example.com into the IP addresses machines actually use.

IPv4 vs IPv6: what's the difference?

IPv4 and IPv6 are the two protocols used to assign IP addresses. They do the same job but differ in format and capacity:

• IPv4 uses a 32-bit address written as four numbers (example: 192.168.1.1). It allows about 4.3 billion unique addresses — no longer enough for the number of connected devices in the world.
• IPv6 uses a 128-bit address written in a longer hexadecimal format (example: 2600:1512:5c3a:7020:41fa:b723:956e:b762). It provides a practically unlimited supply of addresses and supports more efficient routing.

IPv4 remains widely used, but IPv6 is the long-term standard. Many connections now run both at once (called dual-stack), which is why you may see an IPv4 and an IPv6 address listed together.

What is the difference between a static and dynamic IP?

A dynamic IP changes from time to time — your ISP assigns one from a pool and may rotate it after a reconnection or lease period. Most home connections are dynamic. A static IP stays the same and is usually purchased for servers, remote access, or services that need a fixed address. If your IP looks different from a previous visit, a dynamic assignment is the most likely reason.

What can someone learn from my IP address — and how do I stay private?

On its own, a public IP reveals your approximate location and ISP, not your name, exact address, or browsing history. However, because it can be logged by every site you visit, many people choose to mask it for privacy. The common methods are:

• VPN — routes your traffic through a server elsewhere, so sites see the VPN's IP instead of yours.
• Proxy — similar in effect for specific apps or browsers, though usually without the encryption a VPN provides.
• Tor — sends traffic through multiple relays, showing a Tor exit-node IP.

This tool flags when your connection appears to use one of these, which is a quick way to confirm your VPN is active before you do anything sensitive.

How do I use the What Is My IP tool?

1. Open the page — your public IP and connection details load automatically.
2. Read your IPv4 and (if available) IPv6 address.
3. Review the location, ISP, and any VPN/proxy/Tor flag.
4. Toggle your VPN on or off and refresh to confirm the change.

Frequently asked questions

Why is my IP location slightly wrong?

IP geolocation maps your address to your ISP's registered region, which can place you in a nearby city rather than your exact location. This is normal and not a sign of a problem.

Does my IP address reveal my home address?

No. It shows an approximate area and your ISP. Only your ISP can link an IP to a specific account, and only through a lawful request.

Why does my IP address keep changing?

Most home connections use dynamic IPs that rotate periodically. Using a VPN will also change the IP that websites see.

Is it safe to share my IP address?

A public IP is shared with every site you visit by design, but there's rarely a reason to post it publicly. Mask it with a VPN if you want extra privacy.
