The rapid exhaustion of IPv4 address space available for assignment to Internet service providers and end user organizations by the early 1990s, prompted the Internet Engineering Task Force (IETF) to explore new technologies to expand the addressing capability in the Internet.
The result was a redesign of the Internet Protocol which became eventually known as Internet Protocol Version 6 (IPv6) in 1995.
Of this number, some addresses are reserved for special purposes such as private networks (~18 million addresses) and multicast addressing (~270 million addresses).
IPv4 addresses are usually represented in dot-decimal notation, consisting of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., IPv4 addresses may be presented in various hexadecimal, octal, or binary representations.
IPv6 technology was in various testing stages until the mid-2000s, when commercial production deployment commenced.
Today, these two versions of the Internet Protocol are in simultaneous use.Continue Reading Learn how to understand the difference between bit rate and baud rate in this expert answer. The IP address space is managed globally by the Internet Assigned Numbers Authority (IANA), and by five regional Internet registries (RIRs) responsible in their designated territories for assignment to end users and local Internet registries, such as Internet service providers.Such assignments may be on a static (fixed or permanent) or dynamic basis, depending on its software and practices. It identifies the host, or more specifically its network interface, and it provides the location of the host in the network, and thus the capability of establishing a path to that host.Its role has been characterized as follows: "A name indicates what we seek. A route indicates how to get there." The header of each IP packet contains the IP address of the sending host, and that of the destination host.Being more practical, if you have let's say 155 hosts on your network, you'll surely require a full Class C network address space which provides up to 254 usable IP addresses.This of course moves us into the subnet topic where you can find more information by visiting Search Networking.com's IP addressing and subnetting fundamentals guide and my websites' Introduction to subnetting article.Assigning an IP address (e.g., 192.168.0.1) is a simple as selecting one which is not used within the given network addresses.Assigning a network address (e.g., 192.168.0.0/24) requires you to understand your current and future needs, so you can use the appropriate network numbering scheme, but also select the best suitable subnet mask.For this purpose, an IP address is recognized as consisting of two parts: the network prefix in the high-order bits and the remaining bits called the rest field, host identifier, or interface identifier (IPv6), used for host numbering within a network.The subnet mask or CIDR notation determines how the IP address is divided into network and host parts. Both IP versions however use the CIDR concept and notation.
