About this tool & how to use it

What it does

Shows who an IPv4 or IPv6 address block is registered to, its network and its country of registration, from the regional registry.

How to use it

  1. Type a public IP address, such as 8.8.8.8, and press Look up IP address.
  2. Read who the block is registered to, the network name and the range.
  3. Remember that this is registration data, not where a person is.

Enter an IPv4 or IPv6 address. Private and local addresses have no public registration.

Enter the address and your answer will appear here.

The IP address you enter is sent to our server, which asks the regional internet registry that manages it for its public registration record. We do not keep the address or a history. Nothing you enter is sent to analytics.

Assumptions

  • The record is what the registry published once.
  • The country is the country of registration, not a location.
  • An address inside a large block shows the whole block's owner, which is often an internet provider.
  • The IP address you enter is sent to our server, which asks the regional internet registry that manages it. We do not keep it and keep no history.

How it works

Every public IP address belongs to a block that a regional internet registry assigned to an organization. This tool finds the registry that manages the address (through the public IANA lists) and reads that block's record using RDAP: the network name, the organization, the address range and the country the block is registered in.

Private, local and reserved addresses (such as 192.168.x.x, 10.x.x.x, 127.0.0.1 and 169.254.x.x) are refused with the reason, because they have no public registration and are never contacted.

This is registration data, not a location. The country is the one the block is registered in; it does not say where a device or a person using the address is, and the lookup never identifies an individual or a home address. Many people can share one address, and a VPN or a mobile network can place a user far from the registered country. Approximate location needs a separate data source and is not included.

Assumptions

  • The record is what the registry published once.
  • The country is the country of registration, not a location.
  • An address inside a large block shows the whole block's owner, which is often an internet provider.
  • The IP address you enter is sent to our server, which asks the regional internet registry that manages it. We do not keep it and keep no history.

Example

Input: an address in a block named EXAMPLE-NET, registered to Example Broadband LLC in the United States

Result: 203.0.113.7 is part of a block named EXAMPLE-NET, registered to Example Broadband LLC, registered in United States.

Questions

Does this show where someone lives?

No. It shows who a block of addresses is registered to. It never identifies a person or a street address.

Why is the country different from where the user is?

The country is where the block is registered. VPNs, mobile networks and companies with offices elsewhere can use addresses registered in another country.

Why was my address refused?

Private, local and reserved addresses have no public registration. To see the public address your own connection uses, open What Is My IP.

Does it show the ASN?

Not yet. The network number needs a data source we have not approved.
