What is IPV4?
IPV4 is an acronym for Internet Protocol Version4. It is the first most widely deployed version of Internet Protocol although it is the fourth version in the series of IP development. IPV4 is referred to as RFC 791 of September 1981 as per its description in IETF publication and replaces the earlier version RFC 760 of January 1980. In the context of network communication IPV4 is used for identification and connection of devices to the Internet. IPV4 does not assure delivery as well as duplicate delivery of the communication and these factors are managed by upper layer transport. IPV4 is used in packet switched layered communication networks and is a connectionless protocol.
