IP lookup

IP address lookup and geolocation — ISP, city, region, country, IPv4 and IPv6.

IP geolocation

Look up any IP address location

If you have an IPv4 or IPv6 address, paste it below and click Get IP Details. Know Your IP Address returns ISP, hostname, country, region, city, coordinates, and a map estimate — the public facts of a connection, not a private identity.

Enter IP address for lookup

What you will get with this tool

You will see

  • The ISP and organization name
  • The IP's hostname, when one exists
  • The country it is in
  • The region / state
  • The city (a best guess — see accuracy)
  • Latitude and longitude of the location
  • ASN, network, and address family
  • IPv4 decimal form, when it applies

What you won't get

  • A person's name
  • The exact location or street address
  • A phone number
  • Their email address

Those limits are the point. Privacy rules exist to protect internet users like you. An IP is a network address, not an identity file.

A word about accuracy

IP location is inferred from registries and ISP data. It is usually strong at country level, weaker at city level, and never a pin on someone's front door. Outside the US and Europe, city-level guesses inside a 25 mile / 40 km radius are often only around 55%.

99%Country
90%State / region
81%City (about 25 mi)

Treat city and map pins as a region estimate, not an exact location.

Hide my IP address

Complete IP details

After you click Get IP Details, the card lists the public record of that address:

  • Address family (IPv4 or IPv6) and IPv4 decimal form
  • Hostname from reverse DNS, when a PTR record exists
  • ASN, ISP / organization, and network range
  • Assignment or connection type, if the registry publishes it
  • Country, region, city, and postal code
  • Latitude and longitude, plus a map of that proximity

That is the same class of facts you see for your own IP on the My IP page. Anyone can look up a public address. That does not mean they can look up you.

More facts about looking up IP addresses

Most people only care that the connection works. A little knowledge still helps — especially when you need to find an IP address, check a VPN, or understand what a log entry means.

Typical reasons to use IP lookup:

  • An IT person needs a public IP to troubleshoot a home or office connection.
  • You are on a VPN and want to confirm the address the internet actually sees.
  • You have an IP from a log, email header, or server, and want ISP and location.

On the Know Your IP Address home page, your public IP appears automatically. This IP Lookup page is for any address you already have — paste it, get details, see the map.

If you already have an IP

Once you have a number, lookup is paste-and-click. We do not teach tricks to harvest other people's addresses. A public IP shows up in ordinary internet traffic because the other side has to know where to send a reply — websites, mail systems, and apps you already talk to.

That number is public in the same sense a street exists on a map. It is not a name, a phone, or a front door. Use lookup to understand a connection, not to pretend you found a person.

Your IP is public. That does not mean you are exposed

Sites you visit can see the IP you connected from. Companies use region-level IP data for fraud checks and to see which cities are opening a shop. They do not need your apartment number for that.

If a story and a connection disagree — someone claims one country, geodata points at another — treat it as a clue. Databases lag. Mobile carriers and VPNs blur the picture on purpose.

To show a different public IP, use a VPN. Then confirm it on My IP or read Hide My IP.

What an IP address is, in plain language

An IP address is how devices find each other. If you do not have one, you are not on the internet. Other machines would have no route to send a page back to you.

Think of it like a mailing address for data. Your home address tells the postal system where to deliver a package. Your IP tells routers where to deliver packets.

IP stands for Internet Protocol. It usually sits next to TCP, Transmission Control Protocol — agreed rules for sending data in order and retrying if something drops. People say “IP address,” or just “your IP.”

A computer also has a MAC address on the network card. That stays on the local network. The IP is what gets you onto the public internet. The nickname you gave the laptop (“Studio PC”) is for humans. The internet routes on the number.

Who keeps the internet's address book

No single company owns the internet. A few organizations steward names, numbers, and protocols:

  • ICANN — names and number coordination.
  • IAB — architectural oversight for protocols.
  • IETF — working groups that write the standards.
  • Internet Society (ISOC) — the broader open-internet community.

Changes often start as an RFC — a Request for Comments. On the standards track you will see proposed, draft, and full standards. Other labels keep the archive usable: BCP (best current practice), historic, and experimental.

From protocol to hardware

On local networks that is usually Ethernet (wired or Wi-Fi). A network interface — NIC or adapter — plugs your device into that fabric. Each interface has a burned-in MAC address. IP rides on top so packets can leave the building and still find their way back.

IPv4 and IPv6

Most addresses people still recognize — four numbers separated by dots — are IPv4. That pool is 32 bits, about 4.3 billion addresses. In the 1980s that sounded endless. It was not.

IPv6 uses 128 bits: about 340 undecillion addresses — 340 trillion trillion trillion. The format uses hex and colons. Your browser does not care which version carried the page.

Both can be active at once. On Know Your IP Address you can see the public IPv4 for this visit, and the tools menu can check whether IPv6 is visible too. If IPv6 is missing, that is common. It does not mean the connection is wrong. Dual-stack networks speak both, and IPv4 will stay in use for a long time.

What to do next

Paste an address into Get IP Details. Check your own number on My IP. Open the tools arrow on the home page for DNS, reverse DNS, maps, and health signals. If you want the public number to change, start with Hide My IP.
