IANA IPv4 Address Space Allocation for Subnet

The Internet Assigned Numbers Authority (IANA) is responsible for global IP address space allocation to Regional Internet Registries (RIRs). The available IPv4 address space is typically allocated to RIRs as /8 prefix blocks, and the RIRs delegate smaller blocks of their address pools to Local Internet Registries (LIRs) like Internet Service Providers and other organizations in their designated locations.

  • IP Address Representations

An IPv4 address is defined as a 32-bit number, and thus it can be written in any notation that is capable of representing a 32-bit integer value. If human-readability is a requirement, IPv4 addresses are most often expressed in quad-dotted decimal notation with 4 octets ranging from 0 to 255 each.
Note: You should avoid IP addresses with zero-padded decimal octets like or because they might impose an ambiguity with octal numbers.
