What Is My IP Address, and What It Tells Everyone

Every site you open learns one thing before you click anything: your IP address. What it actually reveals, what it does not, and how to see yours in ten seconds.

In short

• Your IP is the return address of your connection. Without it, nothing could reach you back.
• It reveals your internet provider and your approximate area, usually the city or the region. It does not reveal your street, your name or your device.
• Your provider knows exactly who holds that address at any moment, and keeps that record.
• A VPN replaces the address sites see with the address of the exit server. Your provider then sees an encrypted connection to one machine instead of a list of everywhere you went.
• Check yours on our leak test: it shows the address, the DNS resolver, WebRTC and whether anything is escaping the tunnel.

What an IP address actually is

Every device that speaks to the internet needs an address, the same way a letter needs one. When you open a page, your request carries that address so the answer knows where to come back to. No address, no reply.

Two versions exist side by side. IPv4 looks like 203.0.113.42, four numbers between 0 and 255. There are about 4.3 billion of them, which ran out years ago. IPv6 looks like 2001:0db8:85a3::8a2e:0370:7334 and exists because of that shortage.

Most people never see either, and that is fine. What matters is the second part: who can see yours, and what they learn from it.

What it reveals about you

Your internet provider. Address blocks are allocated to companies, and those allocations are public. Anyone can look up which provider owns the range your address sits in.

Your approximate location. Geolocation databases map address ranges to places. In a city you usually land within the right city, sometimes the right district. On mobile networks you can land in a completely different city, because the operator routes traffic through a regional hub.

That it is you, across sites. Different sites cannot compare notes directly, but anything embedded on many sites at once, an ad network or an analytics script, sees the same address on all of them.

What it does not reveal

This is where most articles exaggerate.

An IP address does not contain your name, your street address or your phone number. It does not identify your device. It cannot be used by an ordinary website to find out who you are.

The link between an address and a person exists in one place: at your internet provider. They know which subscriber had which address at which time, and they keep that record for as long as local law tells them to. That link can be requested by a court. It is not something a random site can pull.

So the honest framing is not «anyone can find you by IP». It is: every site sees your provider and your area, and your provider sees every site.

See yours right now

Open the leak test. It shows four things:

• The IPv4 address sites currently see, and the provider it belongs to.
• Whether an IPv6 address is leaking alongside it.
• Which DNS resolver answers your lookups, which shows who learns the names of the sites you visit.
• Whether WebRTC is handing out a different address from inside your browser.

Nothing about the check is stored. It runs, it shows you the result, it forgets.

How to change what sites see

A VPN. Your traffic goes encrypted to an exit server and leaves from there, so sites see the server’s address. Your provider sees that you connected to one machine and nothing about what you did after that.

Tor. Stronger, slower, free. Several relays instead of one, no single operator sees both ends.

A proxy. Changes the address for one app or one browser, usually without encrypting anything. Useful for geography, not for privacy. The difference is covered in proxy or VPN.

Mobile data instead of wifi. Changes the address, changes nothing else, and the operator still sees everything.

The part people get wrong

Hiding your IP is not anonymity. If you log into an account with your name on it, the address you came from stops mattering. Browser fingerprinting, cookies and logins identify you far more reliably than an address ever did.

A VPN solves one specific problem: it stops your provider from building a list of everywhere you go, and it stops sites from seeing where you connect from. That is worth having. It is not invisibility, and anyone selling it as invisibility is selling you something else.

FAQ

Can someone find my home address from my IP?

No. Geolocation gets to a city or a region. The subscriber record that ties an address to a person sits with your provider and is released on legal process, not on request.

Does my IP change?

Usually yes. Most home connections get a dynamic address that changes periodically or on reconnect. Static addresses exist, mostly for business lines.

Does a VPN hide my IP completely?

It replaces the address that sites see. Your provider still sees that you are connected to a VPN server, they just stop seeing where you go from there.

Why does my IP show the wrong city?

Geolocation databases are approximations, and they lag behind reality. Mobile networks are worse, because traffic is routed through regional hubs that can be hundreds of kilometres away.

Is my IPv6 address a separate risk?

It can be. If the tunnel only carries IPv4 and your provider gives you IPv6, that traffic can go around the tunnel. Our exits are IPv4-only and the AmneziaWG profile routes IPv6 into the tunnel and drops it there. The leak test will tell you in seconds.
