Post comment/reviewWhat is IPv4?
Internet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP).
Allocations to RIRs are made in line with the Global Policy. All other assignments require IETF Review.
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.
IPv4 have will be replaced with 
IPv6, but not soon.
