IP Lookup
Enter any IPv4 or IPv6 address to see the network that operates it and the country it is registered in.
Results appear here: the network operator, its network number, and the country.
What an IP lookup tells you
Every public IP address belongs to a block that is registered to an organization, usually an internet provider, a hosting company, or a large business. A lookup reads those public records and returns who operates the block and where it is registered.
- Network is the organization that operates the address. For a home connection this is the internet provider, not the person using it.
- ASN is the number that identifies that organization's network to the rest of the internet.
- Country is where the block is registered or used. It is reliable at country level. Anything finer is an estimate.
- Type says whether the address is public or belongs to a reserved range.
What it cannot tell you
A lookup does not reveal a person's name, a street address, or what the address has been used for. Only the provider that assigned it knows which customer had it at a given time. Our guide to what your IP address reveals goes through the limits in detail.
Private and reserved addresses
Addresses such as 192.168.1.1, 10.0.0.5, and 127.0.0.1 are reserved. They are reused inside millions of separate networks, so there is no single owner to find. For these the tool names the reserved range and stops there. Nothing is sent to a data provider. See public vs private IP addresses for what each range is for.
Where the data comes from
Results for public addresses come from IPinfo. Details about your own connection on the home page come from Cloudflare, the network that serves this site, and include a city-level estimate that this tool does not.
