The basics
What is an IP address?
An IP address (Internet Protocol address) is a number that identifies a connection on a network, so data knows where to go. Think of it as the return address on a letter: every time you open a website, your device sends a request from your IP address, and the website sends the page back to it.
The address at the top of this page is your public IP address. Your internet provider assigns it to your connection, and every device on your home network, from your laptop to your phone and TV, usually shares it when talking to the internet.
IPv4 and IPv6
There are two versions of IP addresses in use today. IPv4 is the original, written as four numbers from 0 to 255 separated by dots. It allows about 4.3 billion addresses, which is not enough for every device in the world. The last free blocks were handed out in 2011, and providers now make IPv4 stretch by letting many devices share one address.
IPv6 is the long-term fix. Its addresses are four times longer, written in hexadecimal and separated by colons, and there are enough of them to give every device on Earth its own many times over. Most modern devices and networks support both, and close to half of the traffic reaching large services such as Google now uses IPv6.
| Property | IPv4 | IPv6 |
|---|---|---|
| Example | 203.0.113.42 | 2001:db8::8a2e:370:7334 |
| Length | 32 bits | 128 bits |
| Number of addresses | About 4.3 billion | About 340 undecillion (3.4 × 10³⁸) |
| Written as | Four numbers, 0–255, separated by dots | Eight groups of hex digits separated by colons; runs of zeros can be shortened to :: |
| Sharing | Common: many devices share one address (NAT) | Rare: every device can have its own public address |
Public and private IP addresses
Your router has one public IP address facing the internet, and hands out private IP addresses to the devices inside your home. When your laptop loads a website, the router swaps its private address for the public one on the way out and back again on the way in. This is called network address translation (NAT).
Private addresses come from reserved ranges that are never used on the public internet, so the same addresses can be reused in millions of homes and offices:
| Range | Typical use |
|---|---|
192.168.0.0 – 192.168.255.255 | Home routers and small networks |
10.0.0.0 – 10.255.255.255 | Company networks and some home routers |
172.16.0.0 – 172.31.255.255 | Company networks, containers and virtual machines |
100.64.0.0 – 100.127.255.255 | Carrier-grade NAT: addresses your provider shares between customers |
fc00::/7 | Private (unique local) IPv6 addresses |

What can your IP address reveal?
Every website you visit sees your public IP address. From it, a website can usually work out:
- Your approximate location: country, region and often city.
- Your internet provider, or the company or university network you are on.
- Whether you are likely on a mobile network, a VPN or a data center.
- Your likely time zone, which is why some sites greet you in the right language.
It does not reveal your name, your street address, your exact position or your browsing history. Only your internet provider can link an IP address to a customer, and in most countries it does so only when required by law.
Can you hide your IP address?
Yes. A VPN, the Tor Browser or a proxy sends your traffic through another server, so websites see that server's IP address instead of yours. Each has trade-offs in speed, cost and how much it actually protects. Our guide on how to hide your IP address compares them, and what is a VPN? explains the most popular option in plain terms.

Frequently asked questions
Does my IP address show where I live?
No. An IP address points to an area, not a home. Most lookups are accurate to the city or region, and sometimes only to the country. Only your internet provider knows which customer used an address at a given time, and it normally shares that only with the police under a court order.
Why is the location shown here wrong?
IP locations are estimates based on where your internet provider has registered or routes its addresses. If you use a VPN, a proxy, iCloud Private Relay or a mobile network, the location is often that of the VPN server or the provider's nearest hub, which can be far from you.
Does my IP address change?
Usually, yes. Most home and mobile connections get a dynamic IP address that can change when your router restarts or after a set time. Businesses and some home users pay for a static IP address that never changes.
Can someone hack me with my IP address?
Not on its own. Your IP address is visible to every website you visit, and that is normal. It can be used to aim attacks at your router, so keep its firmware updated, change the default admin password and don't open ports you don't need.
Why don't I see an IPv6 address?
IPLookr currently receives connections over IPv4 only, so your browser always reaches us over IPv4, even if your connection also supports IPv6. The address shown is the IPv4 address websites see when you visit them over IPv4.
What is the difference between my public and my local IP address?
Your public IP address is the one the internet sees and is shared by every device on your home network. Your local (private) IP address, such as 192.168.1.23, identifies one device inside your network and is only visible to your router and other devices on it.
What is an ISP and an ASN?
An ISP (internet service provider) is the company that connects you to the internet. An ASN (autonomous system number) identifies a network on the internet, such as your ISP's, and is how networks find routes to each other. IPLookr shows both for your connection.
Does IPLookr store my IP address?
No. Your IP address is read from your connection, shown back to you and forgotten. We don't log it, save it or share it. Device details such as your browser and screen size are read in your browser and never sent to us.
