What Is My IP Address — And What Does It Reveal About Me?

Your IP address is the one piece of identifying information that every single website you visit sees by default. You do not have to sign in, click anything, or accept a banner for a site to know your IP. The connection itself announces it.

This guide is the practical version: what an IP actually is, what a site can learn from it, what it cannot, and how to check exactly what your own connection is leaking right now. If you want to see it before you read about it, the Uttir My IP tool shows you the answer in your browser, with no signup and no upload.

The 30-second explanation

Every device on the internet needs an address to receive replies, the same way every house needs a street address to receive mail. That address is your IP (Internet Protocol) address. For most home and mobile connections, it is a number that looks like 158.140.180.116 — four groups of numbers separated by dots, the format called IPv4.

Your internet service provider (ISP) assigns it. When you restart your router, you usually get a new one. When you connect to a different Wi-Fi network, you get a different one. Mobile carriers often assign IPs that change as you move between cell towers.

That is the entire concept. Everything else in this article is a layer on top.

What your IP reveals

From your IP alone, a website can determine five things reliably, and several more with varying accuracy. In rough order of how precise the data is:

1. Your country and city — usually accurate to the city, occasionally to the neighborhood. Geolocation databases map IP ranges to physical locations; the city is correct about 80% of the time for residential connections.
2. Your ISP and the network you are on — Comcast, Verizon, AT&T, PT Telekomunikasi, etc. The IP range is registered to a specific organization, and that information is public.
3. Your ASN (Autonomous System Number) — the network operator that owns the IP block. Useful for figuring out whether a connection is residential, mobile, a hosting provider (e.g. AWS, Google Cloud), or a VPN.
4. Whether you are using a VPN, Tor, or a proxy — IP ranges known to belong to VPN providers are flagged. A connection that says "exit node in Amsterdam" and "AS number belongs to a VPN company" is almost certainly anonymized.
5. Whether you are on a mobile network or Wi-Fi — mobile carrier ranges are usually identified separately.

To see this in action on your own connection, open the My IP tool. It will show you the IP, the city, the ISP, the ASN, and whether the connection looks anonymized — all from public data, in your browser.

What your IP does not reveal

There is a long list of things people assume an IP reveals but does not. Knowing the boundary matters more than knowing the list, because the wrong assumptions are the ones that lead to bad decisions.

• Your name — an IP is not tied to a person. Your ISP knows who you are (your account is linked to the IP they assigned), but a website does not, and cannot, get your name from your IP alone.
• Your exact street address — geolocation gets the city right, but the address level is usually wrong. This is why "find my house by IP" is a TV trope, not a thing.
• Your browsing history — a site sees the IP you used when you connected to it. It does not see what other sites you visited. Only your ISP can see the full list, and they do not share it with random websites.
• Your device or browser — your IP says nothing about whether you are on a phone, laptop, or desktop. Your browser's user agent string does, but the IP does not.
• Your files or passwords — a site sees the IP. It cannot reach into your computer through the IP. A malicious site can do bad things via the browser, but not via the IP itself.

If someone tells you they can identify you or your home address from your IP, they are wrong, lying, or about to ask you to click a phishing link.

How accurate is IP geolocation, really?

It depends on the network type:

• Country: 95–99% accurate. Almost always correct.
• City: 70–85% accurate for residential IPs. Mobile carrier IPs are often less precise — a connection in Jakarta may be geolocated to "Jakarta" but the city-level accuracy varies.
• Postal code / neighborhood: Sometimes accurate, sometimes wrong by 20 km. Do not trust this for anything important.

The IP Geolocation Lookup shows you exactly what one provider (ipwho.is) reports for any IP, so you can see the kind of accuracy you are working with.

Why websites log your IP

Logging IP addresses is so universal that almost every site does it by default. The legitimate reasons are concrete: rate limiting (block someone making 10,000 requests per second), abuse prevention (block the IP that just tried to brute-force your login), fraud detection (flag a login from a new country), and analytics (count unique visitors).

The less legitimate reasons — building advertising profiles, selling location data — also exist, but most reputable sites do not do this. The law in many jurisdictions (the EU under GDPR, California under CCPA) restricts what can be done with IP addresses because they are considered personal data.

Should you hide your IP with a VPN?

Probably not for everyday use, but it depends on what you are trying to do. Honest answer:

• If you just want privacy from ad networks: A reputable VPN is fine. It is one layer of many. It does not make you anonymous; it just changes which companies see your IP.
• If you are doing anything where the stakes are real (journalism, activism, etc.): A commercial VPN is not enough. You need Tor, and you need to understand what Tor does and does not do. Commercial VPNs have been compelled to log and hand over user data in the past.
• For most people, most of the time: A VPN is mostly a cost with a small privacy benefit. The biggest practical win is using HTTPS so the sites you visit cannot see what you do on them, even if your IP is visible.

The My IP tool will tell you whether your connection is currently being flagged as a VPN, which is a quick way to verify the VPN is actually working.

How to check your own IP safely

The Uttir My IP tool works like this: you open the page, the page asks three public services what they see when you connect, and the answers are shown to you. Your IP is never sent to Uttir, because the tool runs entirely in your browser — it talks directly to the IP-info services, not to a Uttir server.

1. Open /my-ip in your browser.
2. The page shows your public IP, the city, the ISP, the ASN, and a small flag for VPN/Tor/proxy detection.
3. Click Refresh if you want to see it update after switching networks or toggling a VPN.

You can also look up any other IP you have — for example, an IP from a server log — with the IP Geolocation Lookup tool. Paste the IP, click, and the same fields come back.

Common questions

What is the difference between IPv4 and IPv6?

IPv4 addresses look like 192.168.1.1 (four numbers, 0–255). IPv6 addresses look like 2001:db8::1 (eight groups of hex, separated by colons, with shortcuts for groups of zeros). IPv6 exists because we ran out of IPv4 addresses; there are about 4 billion IPv4 addresses and the world now has more internet-connected devices than that. The My IP tool shows whichever type your connection uses.

Can someone hack me with my IP?

No. The "hacking" in TV shows where someone types an IP into a box and gets remote access to a webcam is a movie invention. Knowing an IP gives you the rough location and the ISP. It does not give you a way in. The actual security threats come from software vulnerabilities on the device, not from the IP being visible.

Why does my IP change?

Most ISPs assign IPs dynamically from a pool. Each time your router reconnects, you may get a different IP from the pool. Some ISPs charge extra for a static IP, which is a fixed address. Home connections almost always use dynamic IPs; servers (hosting, email) almost always use static ones.

Is my IP the same on every device?

On most home networks, yes. Your router gets one public IP from the ISP, and every device in your house shares that one IP when talking to the internet. Inside your house, each device has a different private IP (usually 192.168.x.x), but those are not visible to websites.

Bottom line

Your IP is public by design. It is not a secret, and it is not enough to identify you. The things to actually worry about are different: using HTTPS so the connection is encrypted, using unique passwords so a leak from one site does not compromise others, and being skeptical of any "find anyone by their IP" claim because it is almost always a scam.
