INTERNET PROTOCOL ADDRESS SPACE
The allocation of Internet Protocol version 4 (IPv4) address space to
various registries is listed here. Originally, all the IPv4 address
spaces was managed directly by the IANA. Later parts of the address
space were allocated to various other registries to manage for
particular purposes or regional areas of the world. RFC 1466
documents most of these allocations.
