The tool above shows your public IP address along with your ISP, location, and a map of your approximate area. Below, we cover what a public IP address actually is, what it reveals about you, and what someone could do with it.

What Is a Public IP Address?
A public IP address is a unique number assigned to your internet connection by your Internet Service Provider (ISP). Every device that connects to the internet needs one, because it’s how data finds its way back to you. When you load a webpage, your request goes out from your public IP, and the response comes back to it.
Think of it like a postal address for your internet connection. Without it, websites wouldn’t know where to send the data you’re requesting.
IPv4 vs. IPv6: The Two Types of IP Addresses
There are two formats your IP address can take:
- IPv4 (Internet Protocol Version 4)
- Example:
192.168.1.1 - The older, more common format.
- Uses a 32-bit number, which limits it to about 4.3 billion unique addresses.
- Example:
- IPv6 (Internet Protocol Version 6)
- Example:
2001:0db8:85a3:0000:0000:8a2e:0370:7334 - Designed to replace IPv4 as the pool of available addresses ran out.
- Uses 128-bit numbers, offering a practically unlimited supply of unique addresses.
- Example:
Most home connections still use IPv4, though IPv6 adoption is gradually increasing. Some connections use both simultaneously.
How to Check Your Public IP Address
The quickest way to check your public IP address is to use the tool at the top of this page. It shows your IP instantly, along with your ISP, city, region, and an approximate location on a map.
If you prefer other methods, here are a few options:
- Search “what is my IP” on Google — Google displays your public IP directly in the search results.
- Use your router’s admin panel — Log into your router (usually at 192.168.1.1) and look under the WAN or internet status section.
- Use a command line — On Windows, open Command Prompt and run
curl ifconfig.me. On Mac or Linux, open Terminal and run the same command.
Keep in mind that your public IP is assigned by your ISP, not your device. All devices on the same home network share the same public IP.
What Does Your IP Address Reveal?
Your public IP address reveals more than most people realise, though less than some fear. Here’s what it actually exposes:
- Your approximate location: country, region, and usually your city
- Your Internet Service Provider (ISP)
- Your connection type in some cases (home broadband, mobile data, etc.)
- Your timezone
What it does not reveal is your name, home address, email, or any personal account details. The location data comes from IP address registries and is often accurate to the city level, but rarely more precise than that.
What Can Someone Do With Your IP Address?
Your IP address is visible to every website and service you connect to, so it’s not secret information. That said, it’s worth knowing what someone could realistically do with it.
Geo-target you with ads
Advertisers use your IP to serve location-relevant ads. This is the most common use of IP data and is largely harmless.
Get a rough idea of where you are
As covered above, your IP can pinpoint your city or region. It won’t give someone your street address or building.
Attempt to probe your network
Someone with your IP could try scanning your router for open ports or known vulnerabilities. Modern routers block most of this by default, but it’s one reason to keep your router firmware updated and avoid using default admin passwords.
Target you with a DoS attack
In rare cases, particularly in online gaming disputes, someone might flood your connection with traffic to disrupt it. This is illegal in most countries and uncommon outside of targeted harassment scenarios.
Submit legal requests to your ISP
Law enforcement or copyright holders can submit requests to your ISP to connect your IP address to your account. Your IP alone doesn’t identify you, but your ISP holds the link between the two.
The honest summary: most people will never experience anything beyond targeted ads. The more serious risks exist but require additional effort and usually a specific reason to target you. If you’re concerned, using a VPN removes your real IP from the equation entirely.
Does My IP Show My Exact Location?
No, not your exact location. IP geolocation typically gets your country right every time, your region or state most of the time, and your city fairly often. It rarely gets more specific than that, and it can sometimes be off by a significant distance.
The reason is that IP geolocation databases map IP addresses to the location of your ISP’s infrastructure, not to your physical device. If your ISP routes traffic through a data centre in a neighbouring city, that’s the location that shows up. According to research on IP geolocation accuracy, city-level accuracy varies considerably depending on the provider and region.
If you’ve ever seen the wrong city in an IP lookup tool, that’s why. It’s not a bug — it’s a limitation of how IP geolocation works.
How to Change or Hide Your Public IP Address
Your ISP assigns your public IP, but there are a few practical ways to change or mask it:
Restart your router
If your ISP uses dynamic IPs (which most home connections do), turning your router off for 10 minutes and restarting it may result in a new IP being assigned. This isn’t guaranteed — some ISPs reassign the same IP.
Use a VPN
A VPN routes your traffic through a server in another location, replacing your real IP with the server’s IP. It’s the most reliable way to mask your public IP and also encrypts your traffic in the process. Reputable options include:
Use a proxy server
Proxies work similarly to VPNs in that they route your traffic through an intermediary server. The key difference is that proxies don’t encrypt your traffic, making them less secure. They’re fine for basic IP masking but not recommended if privacy is the goal.
Contact your ISP
You can request a new IP address directly from your ISP. Not all providers offer this, and those that do may charge for a static IP assignment.
Public IP vs. Private IP: What’s the Difference?
| PUBLIC IP ADDRESS | PRIVATE IP ADDRESS |
| Used externally for communication over the internet | Used internally for communication within your home or office devices |
| Assigned by an ISP | Assigned by a local router or a DHCP server |
| Unique | Not unique and may be reused in other networks |
| Example: 8.8.8.8 | Example: 192.168.1.1 |
| Used to identify individual devices on the open internet | Used to segment a larger network into smaller subnetworks |
In short: your private IP handles communication within your home network (your phone talking to your printer, for example), while your public IP is how the rest of the internet identifies your connection.
Frequently Asked Questions
What is my public IP address?
Your public IP address is the unique number your ISP assigns to your internet connection. You can check it using the tool at the top of this page.
What can someone do with my IP address?
They can see your approximate location (city/region level), serve you geo-targeted ads, and in rare cases attempt to probe your network or disrupt your connection. They cannot access your device, files, or personal accounts using your IP alone.
Can someone track me using my public IP?
Not directly to your home address. Your IP reveals your general location and ISP, but not your name or exact address. Websites can combine your IP with other data like cookies to build a broader profile over time.
Why does my IP address show the wrong location?
IP geolocation maps addresses to your ISP’s infrastructure, not your physical device. If your ISP routes traffic through a data centre elsewhere, that location shows up instead of yours. This is a known limitation of IP geolocation, not an error.
Why does my IP address change?
If you have a dynamic IP, your ISP may assign you a new one periodically or when you restart your router. A static IP stays fixed unless you request a change.
Will using a VPN slow down my internet?
A VPN adds a small amount of overhead since your traffic is encrypted and rerouted. Premium services minimise this by using high-capacity, well-optimised servers. For most everyday tasks you won’t notice the difference.
