What your IP address actually says about you
Your IP address is the one identifier you hand to every website you visit, before the page has even finished loading. Here is what it contains, what it does not, and what you can do about it.
01What websites learn the moment you connect
Every request your browser makes carries your public IP address in the packet header. It has to: without a return address, the server has nowhere to send the page back to. That single number, cross-referenced against public routing registries, is enough for any site to look up your internet service provider, the autonomous system number (ASN) that carries your traffic, the country and usually the city or region your connection exits from, and whether that exit point belongs to a home broadband line, a mobile carrier, a corporate network or a data centre.
What that adds up to is a rough profile: someone in a particular metro area, on a particular ISP, on a residential connection. Advertising networks pair it with cookies and browser fingerprints to recognise you across unrelated sites. Streaming services use it to decide which catalogue you are allowed to see. Fraud systems use it to decide whether today's login looks like yesterday's. None of that requires your permission, and none of it is visible to you unless you go looking — which is what the readout at the top of this page is for.
02IPv4 and IPv6 are usually both in play
IPv4 addresses look like 203.0.113.42: four numbers, about 4.3 billion combinations in total, and the pool ran dry years ago. IPv6 addresses look like 2001:db8::42, and there are enough of them to hand one to every grain of sand on Earth several times over. Most modern connections run both at once — a setup called dual-stack — and your browser quietly picks whichever version the destination supports.
That dual-stack behaviour matters for privacy in one very specific way. A VPN or proxy that only tunnels IPv4 will leak your real IPv6 address to any site that speaks it, which undoes the entire point of the tunnel. This page probes each family separately so you can compare them. If your IPv4 shows a VPN exit and your IPv6 shows your home ISP, you have a leak worth fixing.
03Your public IP is not the one in your network settings
Open your device's network settings and you will probably see something like 192.168.1.14 or 10.0.0.5. That is a private address, handed out by your own router, and it means nothing outside your home or office — millions of networks use those exact same ranges simultaneously. Your router performs network address translation, rewriting outbound packets so that everything on your network appears to come from the single public address your ISP assigned to the line.
So there are two honest answers to “what is my IP address”. The private one identifies a device on your local network. The public one, shown at the top of this page, identifies your entire household to the rest of the internet. The public address is the one websites see, the one that gets rate-limited, blocklisted or geo-fenced, and the one worth paying attention to.
04Static, dynamic and shared addresses
Most home connections get a dynamic IP: the ISP leases you an address, and it may change when your router reboots, when the lease expires, or in practice almost never, depending entirely on the provider. Businesses often pay for a static address that stays fixed, because mail servers, remote access and VPN endpoints need a stable place to be found.
Increasingly, mobile networks and some fixed-line ones use carrier-grade NAT, where hundreds or thousands of subscribers share a single public address. That is good for your anonymity, because your traffic is mixed in with everyone else's, and bad when somebody else on that address gets it blocklisted, because you inherit the reputation. It also explains why your reported location is sometimes a city you have never visited: the address belongs to the carrier's exit point, not to you.
05How to change or hide your IP address
A VPN is the usual answer. It routes your traffic through a server somewhere else, so websites see that server's address instead of yours, and your ISP sees only an encrypted tunnel rather than a list of destinations. Tor goes further, bouncing each connection through three volunteer relays so that no single hop knows both who you are and where you are going, at a real cost in speed. A plain proxy is the lightest option and usually the weakest, covering one application rather than the whole device.
Cheaper tricks work too, within limits. Rebooting a router on a dynamic connection often yields a fresh address. Switching from Wi-Fi to mobile data moves you onto an entirely different network. Neither is private in any meaningful sense — both simply give you a different number that is still tied to an account in your name — but both are enough to escape a stale rate limit or a temporary block.
06What an IP address cannot do
An IP address is not a home address. Geolocation databases map ranges to places by inference, and they are routinely wrong by tens of miles. The coordinates you see usually point at an ISP facility, the centroid of a city, or — in a few famously unfortunate cases — an arbitrary default somewhere in the middle of a country. Nobody can paste your IP into a website and get your doorstep.
Your ISP is the exception. It knows precisely which account held which address at which moment, it keeps those records, and it can be compelled to produce them by a court. That is the real threat model: not a stranger geolocating your house, but the chain of custody between an address and a subscriber. Everything else — the tracking, the profiling, the geo-blocking — is statistical, which is exactly why reducing the signal you give off is worth the effort.
How to find your IP address on any device
The fastest answer is the number at the top of this page: it is your public address, read straight off the connection you are using right now, with no app to install. If you need the private address your router handed to one specific device, here is where each platform keeps it.
- Windows
- Settings → Network & Internet, then select your active Wi-Fi or Ethernet connection and read the IPv4 and IPv6 rows. From a terminal, ipconfig prints the same values along with the default gateway.
- macOS
- System Settings → Network, pick the active service and click Details. The TCP/IP tab lists the address. In Terminal, ipconfig getifaddr en0 returns the Wi-Fi address on its own.
- iPhone and iPad
- Settings → Wi-Fi, then tap the ⓘ button next to the network you are on. The IP Address row shows the private address. On mobile data iOS does not surface it at all, and the public address above is the one that matters anyway.
- Android
- Settings → Network & Internet → Wi-Fi, tap the connected network, then open Advanced or Network details. The exact wording moves around between manufacturers and Android versions.
- Your router
- Your router's own address appears as the default gateway alongside the entries above — typically 192.168.0.1 or 192.168.1.1. Typing it into a browser opens the admin panel, where the WAN or Internet page shows the same public address this site reports.

01What is an IP address?
It's the return address for your internet traffic. Every site you visit needs it to send data back, which is also why every site can see it. Your ISP assigns it, and it usually reveals your ISP and your approximate city.
02How do I find my IP address?
You already have: the number at the top of this page is the public IP your connection is using right now. Finding the private address your router gave a particular device takes a trip through that device's network settings — the explainer above lists the exact path for Windows, macOS, iOS and Android.
03Can someone find my home from my IP?
Not from the IP alone. Public geolocation usually points to your ISP's hub, often miles away. Your ISP knows exactly who you are, though, and can be legally compelled to share it.
04How do I change my IP address?
On a dynamic home connection, rebooting the router often gets you a new one. Switching from Wi-Fi to mobile data puts you on a different network entirely. A VPN replaces the address websites see without touching your connection. A static address, by definition, does not change until your ISP changes it.
05Is it dangerous if someone knows my IP address?
On its own, not very. It reveals your ISP and approximate region, and it lets someone aim a denial-of-service flood at your connection, which is disruptive rather than dangerous. It does not give anyone access to your devices, files or accounts. Treat it as mildly identifying, not as a secret.
06Does this site log my IP?
No. Your IP is used to answer your request and then discarded. Caches and rate limits only ever see a salted one-way hash that expires within an hour. We run no third-party trackers.
07What's the difference between IPv4 and IPv6?
IPv4 looks like 203.0.113.42 and ran out of addresses years ago. IPv6 looks like 2001:db8::42 and has practically unlimited space. Many connections use both, which matters because a VPN that only tunnels IPv4 can leak your real IPv6.
08Does a VPN make me anonymous?
It hides your IP from websites and your browsing from your ISP. It doesn't stop fingerprinting, logged-in accounts or cookies from identifying you. Think of it as one layer, not an invisibility cloak.
09Does incognito or private browsing hide my IP?
No. Private browsing only stops your own browser from keeping history, cookies and form data after you close the window. Every site you visit still sees the same public IP address, and so does your ISP. Reload this page in a private window and the number will not budge.
10What is an ASN, and why does this page show one?
An autonomous system number identifies the network that announces your IP range to the rest of the internet — usually your ISP, sometimes a hosting company or a VPN provider. It is a more reliable signal than geolocation: the ASN is registered fact, while the city is an estimate, and it is what tells you whether an address belongs to a home line or a data centre.
11Why does my location look wrong?
Geolocation databases map IP ranges to places, and they're approximate. Mobile networks, CGNAT and VPNs make it fuzzier. That's actually good for your privacy.
