What Does an IP Address Tell You? What It Reveals and What It Can't

Every website, app and game server you connect to sees your public IP address, because that’s where replies are sent. The box below shows what this site can tell from yours right now. The sections after it explain what an IP address reveals, what someone can and can’t do with it, how tracing works and when to act.

What this website sees from your IP address right now

This site gets these details from your connection alone. It doesn’t use your browser’s location sharing or your device’s GPS.

• IP address: the public address your router, mobile carrier or VPN uses online. A long one with colons is IPv6.
• Place: where geolocation data puts this address, often a larger city nearby or your provider’s hub.
• Coordinates: the center of that estimated area, not your home.
• Provider: the organization that holds the address, such as your internet provider, mobile carrier, employer, school, a hosting company or a VPN.
• Time zone: the time zone of the estimated place.

Websites don’t see the local IP address your router gives each device, such as 192.168.1.20. It only works inside your home network (local IP addresses explained). If the place looks off, see why your IP location can be wrong.

What your IP address reveals about you and what it doesn’t

An IP address is a network address, not a profile. Registries record who holds each block of addresses, and geolocation databases estimate where each block is used. A lookup can only return what those sources contain.

A precise location and your identity come from other sources: your device’s location services, which sites and apps get only with your permission, and accounts, apps or data brokers that store your IP address alongside your details.

What can someone do with your IP address?

Your IP address isn’t secret. Websites, apps, email and game servers see it, and so do people you connect to directly, such as other players in some peer-to-peer games.

What someone can do with your IP

• See your approximate area and provider: the data in the box above. Sites use it for local content and prices, regional licensing and fraud checks.
• Recognize your connection: with cookies and device details, your IP helps sites and advertisers link visits over time and across sites.
• Block or ban it: games and sites ban addresses, and because providers share and reassign them, you can inherit someone else’s ban.
• Flood your connection: a denial-of-service (DoS) attack sends so much traffic that your connection stops working until the attack ends. Against home users, this mostly happens in online gaming and live streaming. It takes you offline but gives no access to your devices.
• Probe it for open services: automated tools routinely scan the entire IPv4 internet, whether or not anyone knows your address. That only matters if a device on your network accepts connections from the internet and has a weak password or an unpatched flaw.
• Use it to scare you: for years, scam emails and fake warning screens have claimed the FBI logged your IP address on illegal sites, sometimes demanding a “fine.” The FBI has said it doesn’t send emails like these.

What someone can’t do with only your IP address

• Find your home: a lookup points to an area. Only your provider knows which customer used an address at a given time, and it normally shares that only under legal process.
• Learn your name, email or phone number: none of these are in registry records or geolocation data.
• See what you do online: your address gives no one access to your traffic. Even your provider, which carries it, can usually see which sites you visit but not what you read or type on HTTPS pages.
• Break into your devices by itself: most home routers have a built-in firewall that blocks connections you didn’t start. An attacker needs an exposed, vulnerable device, or needs you to open a malicious link or file.

Can an IP address be traced? How tracing works

Yes, but only to a network and an account holder. Of the three layers below, only the last reaches a name.

IP lookup databases

Lookup databases estimate where an address is used and which network it belongs to, based on registry data, providers’ own location lists and network measurements. IP lookup services, including the IP lookup API this site offers, return this kind of data. These sources hold no subscriber names, so the results don’t either. Read more about how IP geolocation works and how accurate it is.

Registry records

Five regional internet registries publish who holds each address block through WHOIS and RDAP. For the US and Canada, that’s ARIN. A record names the holder and an abuse contact for reporting misuse. For a home connection, the holder is your provider, not you.

Provider records and legal process

Only your provider knows which customer used an address at a given moment, and only while it keeps those records. Investigators need the address and the exact date and time, plus the port number on addresses that many customers share through carrier-grade NAT.

In the US, a subpoena under 18 U.S.C. 2703 gets investigators the subscriber’s name, address, session times and assigned IP addresses. More detailed records need a court order, and the content of messages generally needs a warrant. In civil cases, such as copyright lawsuits, the other side usually needs a court order to learn who had an address. In the EU, access follows national law, and since August 18, 2026, the e-Evidence Regulation also lets a prosecutor order a provider based in another member state to hand over subscriber data and the IP addresses needed to identify a user.

A trace ends at the account holder, not necessarily the person who used the connection. With a VPN, it leads to the VPN provider first.

Does IPv6 reveal more about you?

With IPv6, each device usually gets its own public address instead of sharing the router’s. To keep it from becoming a long-term ID, most phones and computers use temporary addresses, also called privacy extensions (RFC 8981): random addresses for outgoing connections that, by default, are replaced daily. Only the device part changes: the first half, the network prefix from your provider, stays the same for longer, so sites can still tell that visits come from the same network.

Should you be worried if someone has your IP address?

Usually not. Every site and server you contact already has your IP address. The risk depends on who has it and what your network exposes.

Signs that something is actually wrong:

• Your connection becomes unusable for minutes or hours and every site times out, while your provider reports no outage. That can point to a DoS attack.
• Your router shows settings you didn’t change, runs hot or keeps dropping the connection. The FBI lists these as signs that criminals have taken over a router.
• The router’s device list shows devices you don’t recognize, which can mean someone else is using your Wi-Fi.

What to do if someone has your IP address

If your situation matches the first two rows of the table, you don’t need to do anything.

If someone threatens or attacks your connection

1. Save the messages, with usernames, dates and times.
2. Report the person to the game or platform where it happened.
3. Restart your modem or router to get a new public IP address. This works on many connections with a dynamic address. A static IP address stays the same.
4. Ask your provider for a new IP address if yours doesn’t change or the attacks continue.
5. Report threats to your local police. If you’re in immediate danger, call 911.
6. Report online crimes such as extortion to the FBI’s Internet Crime Complaint Center at ic3.gov.

Close the openings on your router

These steps follow the FTC’s guide to securing your home Wi-Fi network. Menu names differ by brand.

1. Sign in to your router’s settings page (how to find your router’s IP address).
2. Install firmware updates, or replace the router if its maker no longer releases them. In May 2025, the FBI warned that criminals take over such end-of-life routers to route their own traffic.
3. Turn off remote management, UPnP and WPS if you don’t use them.
4. Delete port-forwarding rules you no longer need.
5. Change the router’s default admin password.
6. Set your Wi-Fi security to WPA3 or WPA2 with a strong password. Anything done over your Wi-Fi appears under your IP address.

Hide your IP address from sites and other players

A VPN, or a privacy relay that some browsers and operating systems offer, sends your traffic through its own servers, so sites and other players see its address instead of yours. You then trust that service with what your provider would otherwise see. The FTC suggests researching a VPN app before you install it, including whether it encrypts your data and shares your information.
