Your IP address, explained.
The return address of the internet. Here’s what it says about you (and what it doesn’t).
THE AHA MOMENT
A little clarity. A big difference.An IP address is the return address for internet traffic.
It helps replies find their way back to you. At home, devices often share the public address of your router and have their own local addresses inside your network. An IP can suggest a rough region, but it is not a precise street address or a person’s identity.
A packet’s little adventure
Guide a message from your device through a router to a website and back.
Drag the little message to the router.

A little experiment is the best way to learn. Give something a try.
A return address for internet traffic
When you open a website, your device requests data and needs a way to receive the reply. An IP address helps networks deliver those packets to the right place.
Public and private addresses
Your router usually has a public address visible to websites. Inside your home, your devices often use private addresses. Your router connects those two worlds using network address translation. IPv6 networks can work differently, with globally routable addresses assigned to devices.
Why the address can change
Your internet provider may change it. Switching to mobile data or turning on a VPN can also change the address a website sees. Multiple people can share a public address.
What an IP does not tell you
An IP address is not a reliable street address or a person’s identity. Location services estimate a region using databases, and those estimates can be wrong. An IP check alone also cannot prove that a VPN is secure.
A useful troubleshooting habit
If support asks for your public IP, use the IP tool and copy the result. Share it privately with someone you trust rather than posting it on a public forum.
