What is an IP address?
An IP (Internet Protocol) address is a numerical label assigned to every device connected to a network. It serves two main purposes: identifying the host or network interface, and providing the location of that host in the network. Without IP addresses, devices would have no way to find and communicate with each other across the internet.
IPv4 vs IPv6
IPv4 addresses are 32-bit numbers written as four groups of decimal digits separated by dots, such as 192.168.1.1. They allow for roughly 4.3 billion unique addresses — a number that has been exhausted due to the explosion of internet-connected devices. IPv6 was introduced to solve this problem: it uses 128-bit addresses written in hexadecimal, like 2001:0db8:85a3::8a2e:0370:7334, providing an astronomically large address space of 340 undecillion addresses.
What information can be found from an IP address?
An IP address can reveal the approximate geographic location of a device (typically at the city or region level, not street level), the Internet Service Provider (ISP) or hosting company that owns the address block, the autonomous system number (ASN), the timezone, and whether the IP belongs to a residential, business, or data center network. This information is stored in public registration databases called WHOIS and RIR (Regional Internet Registry) records.
Privacy note
IP geolocation is not precise — it shows a general area rather than an exact address. The accuracy varies widely: it is most reliable at the country level, reasonably accurate at the city level, and unreliable at the street level. VPNs and proxy servers will show the IP of the VPN server rather than your actual device. This tool uses the ipapi.co API to retrieve geolocation data. No IP addresses or lookup results are stored by this tool.
