What is the fastest way to find my public IP?

Open the My IP homepage. Your current public IPv4 or IPv6 address appears automatically.

Is my public IP the same as my private IP?

No. A public IP identifies your Internet connection, while a private IP identifies a device inside a local network.

Why do I have both IPv4 and IPv6?

Many networks support both Internet Protocol versions for compatibility, so a device can use both types.

Does my IP change when I switch to mobile data?

Usually, yes. Wi-Fi and mobile data use different network connections and normally show different public addresses.

Can I find someone’s exact location from an IP?

No. IP geolocation is approximate and does not normally reveal an exact home address or precise GPS position.

How to Find My IP Address on Any Device

Fastest way to find your public IP

Open the My IP checker. Your current public IPv4 or IPv6 address appears automatically, with no command or installation required.

Before following the device instructions, decide which address you need. Your public IP is visible to websites and belongs to your Internet connection. Your private IP identifies your phone, computer or another device inside your home, office or Wi-Fi network.

Which IP address are you trying to find?

Your goal	Address needed	Best place to look

Connect to a printer or computer on the same Wi-Fi	Private IPv4	Network settings on that device
Open the router administration page	Default gateway or router address	Connection details on Windows, Mac, phone or router label
Check an address that does not belong to your current connection	The known public IP	IP Address Lookup

How to find your IP address on Windows

Using Windows Settings

Open Start and select Settings.
Select Network & internet.
Select Wi-Fi or Ethernet, depending on your connection.
Open the connected network or its properties.
Look for IPv4 address and, when available, IPv6 address.

Using Command Prompt

Press Windows + R.
Enter cmd and press Enter.
Enter ipconfig and press Enter.
Find the active Wi-Fi or Ethernet adapter and read its IPv4 or IPv6 address.

The address shown by ipconfig is usually your private network address. Use the My IP homepage to see the public address visible on the Internet.

How to find your IP address on a Mac

Open the Apple menu and select System Settings.
Select Network in the sidebar.
Select your active Wi-Fi or Ethernet connection.
Select Details, then TCP/IP.
Read the IPv4 or IPv6 address assigned to the Mac.

The Network details may also show the router address and how the Mac receives its network configuration.

How to find your IP address on iPhone or iPad

Open the Settings app.
Select Wi-Fi.
Tap the information button beside the connected Wi-Fi network.
Scroll to the IPv4 Address section.
Read the address next to IP Address. IPv6 addresses may appear farther down the same screen.

This screen shows the address used inside the Wi-Fi network. To see the public address, open My IP in Safari or another browser.

How to find your IP address on Android

Open Settings.
Select Network & internet, Connections or Wi-Fi.
Select Internet or tap the connected Wi-Fi network.
Open the network details or settings.
Look for IP address under the network information.

Android menu names vary between Google Pixel, Samsung, Motorola and other manufacturers. If necessary, use the Settings search box and search for “IP address” or “Wi-Fi.”

How to find your IP address on a Chromebook

Select the time in the lower-right corner.
Select the connected Wi-Fi network.
Select the network name again to open its details.
Open the Network section.
Read the IP address shown for the connection.

How to find your IP address on Linux

Using network settings

Open Settings and select Network or Wi-Fi.
Select the settings button beside the active connection.
Look for the IPv4 or IPv6 address in the connection details.

Using the terminal

Open a terminal and enter ip addr. Find the active network interface and read the address beside inet for IPv4 or inet6 for IPv6.

How to find your router’s IP addresses

A router normally has a private address used for its settings page and a WAN address used for the provider connection.

Find the router or default gateway address in your device’s network settings.
Enter that address in a browser while connected to the router.
Sign in using the router administrator account.
Open Internet, WAN or Status.
Read the WAN IPv4 or IPv6 address.

If your provider uses carrier-grade NAT, the WAN address shown by the router may differ from the public IPv4 address displayed by a website. Do not share your router administrator password.

Public IP vs private IP: which one do you need?

Use your public IP when checking what websites see, configuring remote access or identifying your Internet connection. Use a private IP when connecting to a printer, router, computer or another device inside the same local network.

Learn more in our complete public vs private IP guide. You can also enter a different public address in the IP Address Lookup to view its approximate location, ISP and ASN.

How to recognize the address you found

A private IPv4 address commonly begins with 10., falls between 172.16. and 172.31., or begins with 192.168.. These addresses can be reused on many separate local networks and are not routed directly across the public Internet.

127.0.0.1 is the IPv4 loopback address for the device itself, not its network address.
An address beginning with 169.254. is usually link-local and can indicate that automatic IPv4 configuration failed.
An IPv6 address beginning with fe80: is link-local and works only on the local network segment.
The default gateway is usually the router's local address; it is not normally the device's own address.
A MAC address identifies a network interface at the local-link layer and is not an IP address.

A simple test to compare Wi-Fi and mobile data

While connected to Wi-Fi, open the My IP checker and note whether it displays IPv4, IPv6 or both.
Turn Wi-Fi off and confirm that the phone is using its mobile-data connection.
Reload the page and compare the new public address with the first result.
Turn Wi-Fi back on and reload once more to confirm the original network result.

Different results are expected because the two connections normally use different providers or network gateways. If the public IPv4 stays the same for several subscribers, the provider may be using carrier-grade NAT. A VPN can also replace the visible public address with an address belonging to the VPN service.

Why do I see more than one IP address?

A device can have separate addresses for Wi-Fi, Ethernet, virtual networks and other interfaces. It may also use IPv4 and IPv6 at the same time. Temporary IPv6 addresses can provide additional privacy, so more than one IPv6 address may appear.

Read our IPv4 vs IPv6 guide to understand the two address formats.

Does my IP change between Wi-Fi and mobile data?

Usually, yes. Your Wi-Fi connection uses an address associated with its Internet provider, while mobile data uses the carrier’s network. Switching between them can therefore change the public IPv4 or IPv6 address visible to websites.

What to check when no useful IP appears

Confirm that the device is connected to the intended Wi-Fi, Ethernet or mobile network.
Ignore disconnected adapters and virtual interfaces unless you are diagnosing a VPN or virtual machine.
If Windows shows a 169.254.x.x address, reconnect to the network or restart the router before testing again.
If a browser checker does not load, temporarily disable content blocking for the page and retry on another connection.
If the address changes frequently, repeat the test without a VPN and remember that many providers assign dynamic addresses.

IP addresses are useful for network troubleshooting, but an IP alone does not reveal a person's exact home address or prove who was using a connection. Avoid publishing a complete diagnostic screen when only one value is needed.
