During the first decade of operation of the Internet, it became apparent that methods had to be developed to conserve address space. Address exhaustion was not initially a concern in IPv4 as this version was originally presumed to be a test of DARPA's networking concepts. Thus, IPv4 provides an addressing capability of 2 32 or approximately 4.3 billion addresses. These addresses are typically displayed in dot-decimal notation as decimal values of four octets, each in the range 0 to 255, or 8 bits per number. IPv4 includes an addressing system that uses numerical identifiers consisting of 32 bits.

IPv4 was developed as a research project by the Defense Advanced Research Projects Agency (DARPA), a United States Department of Defense agency, before becoming the foundation for the Internet and the World Wide Web. Internet Protocol Version 4 (IPv4) was the first publicly used version of the Internet Protocol.

The full representation may be shortened for example, 2001:0db8:0000:0000:0000:8a2e:0370:7334 becomes 2001:db8::8a2e:370:7334.ĭecomposition of the dot-decimal IPv4 address representation to its binary value IPv6 addresses are represented as eight groups of four hexadecimal digits each, separated by colons. Device mobility, security, and configuration aspects have been considered in the design of the protocol. The use of multicast addressing is expanded and simplified, and provides additional optimization for the delivery of services. In particular, it permits hierarchical address allocation methods that facilitate route aggregation across the Internet, and thus limit the expansion of routing tables. IPv6 provides other technical benefits in addition to a larger addressing space. However, several transition mechanisms have been devised to rectify this. The two protocols are not designed to be interoperable, and thus direct communication between them is impossible, complicating the move to IPv6. The actual number is slightly smaller, as multiple ranges are reserved for special use or completely excluded from use. IPv6 uses 128- bit addresses, theoretically allowing 2 128, or approximately 3.4 ×10 38 total addresses. By 1998, the IETF had formalized the successor protocol. With the rapid growth of the Internet after commercialization in the 1990s, it became evident that far more addresses would be needed to connect devices than the IPv4 address space had available. ĭevices on the Internet are assigned a unique IP address for identification and location definition. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017.

IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion, and is intended to replace IPv4. Internet Protocol version 6 ( IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.
