IP Checker

This free online IP checker instantly shows your public IP address, as seen by websites you visit.

Detecting your IP address...

How to Use the IP Checker

  1. Your public IP address is detected automatically when the page loads.
  2. Click "Copy IP Address" to copy it to your clipboard.
  3. Click "Refresh" to check again, for example after reconnecting to a different network.

How the Address Is Detected

When the page loads, your browser sends a small request to ipify, a public IP lookup service. The service replies with the address that request arrived from, and the page displays it. That is the same address other websites see when you visit them.

The lookup used here returns an IPv4 address, written as four numbers from 0 to 255 separated by dots, such as 203.0.113.25. If your connection uses only IPv6, the lookup can fail and the page will show an error; in that case your device or router settings will show the IPv6 address instead.

Public vs Private Addresses

The address shown here is usually different from the one in your phone or computer's network settings. Devices on a home or office network get private addresses from the router, and the router shares one public address for all of them. Private addresses come from reserved ranges:

Address rangeWhat it means
10.0.0.0 – 10.255.255.255Private network, common in offices and some routers
172.16.0.0 – 172.31.255.255Private network
192.168.0.0 – 192.168.255.255Private network, used by most home Wi-Fi routers
100.64.0.0 – 100.127.255.255Shared address space used by providers for carrier-grade NAT
127.0.0.1Loopback, meaning the device itself

Many mobile and some broadband providers place many customers behind one public IPv4 address, a setup called carrier-grade NAT. If your router's WAN address starts with 100.64 to 100.127, or differs from the address shown here, you are probably behind it, which means you cannot host a server or open ports directly from home without help from your provider.

When You Might Need Your Public IP

  • Giving an IT team or hosting provider an address to allow-list, for example for access to a company server, database or admin panel.
  • Checking whether a VPN is working: with the VPN on, the address shown should belong to the VPN provider, not your own internet provider.
  • Troubleshooting with your broadband provider, or confirming whether you have the static IP you are paying for. A static address stays the same after a router restart; a dynamic one may change.

A public IP address can reveal your internet provider and an approximate area, often only the city or region, but not your house address or name. Linking an address to a subscriber requires records held by the provider.

Frequently Asked Questions

Your public IP address is the address your internet service provider assigns to your connection, which websites and other internet services see when you connect to them.

Most home and mobile connections use a dynamic IP address that can change when you reconnect, restart your router, or switch networks (such as moving from Wi-Fi to mobile data).

This page does not save your IP address. To find it, your browser makes a request to the ipify lookup service, which sees your address in the same way any website you visit does, and the result is shown only on your screen.

Your Wi-Fi settings show the private address your router gave your device, such as 192.168.1.5. This page shows the public address your router or provider uses on the internet. Both are correct; they are on different sides of the router.

Yes. Everyone on the same home or office network shares one public address, and mobile providers using carrier-grade NAT can place many separate customers behind a single address at the same time.
