IPv4 Address Space report

An Internet Protocol address (IP address) is a numerical label assigned to each device on a network. IPv4 addresses are canonically represented in dot-decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 192.168.16.1. Each part represents a group of 8 bits (octet) of the address. So the total IPv4 address space is from 0.0.0.0 to 255.255.255.255. With the IPv4 address space report it is possible to browse the IPv4 address space and see the geolocation, DNS, whois, routing, hosting, domain neighbors, DNSBL, BGP and ASN information of every IPv4 address.
