IP Address Lookup
Find the location, ISP, and organization behind any IP address or domain.
What is an IP Address?
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a network. It serves two primary functions: identifying the host and providing the location of the device in the network.
There are two versions in use today. IPv4 addresses use a 32-bit format (like 192.168.1.1) and support roughly 4.3 billion unique addresses. IPv6 uses a 128-bit format and supports a virtually unlimited number of addresses.
IP lookup tools use geolocation databases to map IP addresses to approximate physical locations. The accuracy varies — you'll typically get the correct city and ISP, but not a street address.
Frequently Asked Questions
What is my IP address?
Your IP address is assigned by your internet provider and identifies your device on the network. It can reveal your approximate location, ISP, and connection type.
What is IPv4 vs IPv6?
IPv4 uses 32-bit addresses (4.3 billion possible). IPv6 uses 128-bit addresses (virtually unlimited). IPv6 is gradually replacing IPv4 as addresses run out.
Can an IP address reveal my exact location?
No. IP geolocation typically shows your city or region and ISP, but not your exact street address. Accuracy depends on the geolocation database.
What is a reverse DNS lookup?
Reverse DNS maps an IP address back to a hostname — the opposite of standard DNS. It's used to verify mail servers and troubleshoot network issues.
