What Is My IP Address, and Why Does It Matter?

The difference between your public and private IP, what an IP address reveals about you, and when you'd actually need to check it.

Every device connected to the internet needs an address to send and receive data — that's your IP address. But "what's my IP" is a more layered question than it looks, because most devices actually have more than one.

Public vs. private IP address

Your private IP is assigned by your router to identify your device on your home or office network (often something like 192.168.1.x) — it's invisible to the outside internet. Your public IP is the address your router uses to represent your entire network to the outside world, and it's what a website sees when you visit it. When people ask "what's my IP," they almost always mean the public one.

What your public IP reveals

A public IP can be used to approximate your general location (city or region, not your exact address), identify your internet service provider, and — combined with other data — contribute to tracking across sites. It does not reveal your name or precise physical address on its own.

How to check your IP

Open the IP Checker.
Your public IPv4/IPv6 address, approximate location, and ISP details appear instantly.

Common reasons to check it

Troubleshooting network issues: confirming your connection is actually reaching the internet with the IP you expect.
Setting up remote access or a VPN: many configurations need your current public IP to whitelist or verify a connection.
Checking if a VPN is working: if your IP address and location don't change after connecting to a VPN, it isn't routing your traffic the way you think.
