How to Find My IP Address

Find your public IP address online and learn how to locate your private IP on Windows, macOS, Android, iPhone, routers, and networks.

The fastest way to find your public IP address is to use an online IP checker. That shows the address websites see right now, including changes caused by VPNs, proxies, mobile data, or office networks.

You can also find your private IP address in device or router settings. Private IPs are useful for local networking, printers, file sharing, and router troubleshooting.

Find your public IP online

Open WhatIsMyIPOnline.com and read the main IP address shown at the top of the page. Use the copy button if you need to send it to a support team.

Find your private IP on a computer

On Windows, check network details in Settings or run ipconfig. On macOS, open Network settings or use the terminal command ifconfig or ipconfig getifaddr en0.

Find your private IP on mobile

On iPhone or Android, open Wi-Fi settings, tap the connected network, and look for IP address or network details. Mobile data may not show the same kind of local address.

Check your router

Your router admin page can show local device addresses, WAN status, DNS settings, and whether your ISP assigned a public address or a shared/private upstream address.

Frequently Asked Questions

Which IP address should I give support?

If a website or service asks what IP they see, provide your public IP. If router or local device support asks, they may need your private IP.

Why are my phone and laptop different?

They may be on different networks, VPN states, or connection types. Wi-Fi and mobile data often use different public IP addresses.

Can my public IP change during the day?

Yes. It can change when your router reconnects, your ISP rotates addresses, or you switch networks or VPN servers.
