IPv4 Address Space report | Overview of all IPv4 subnets and IP addresses available.
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.
