The quick definition: Subnetting is the process of taking a network and splitting it into smaller networks, known as subnets.
Understanding IPv4 Addressing. Configuring the inet6 IPv6 Protocol Family. IPv4 addresses are bit numbers that are typically displayed in dotted decimal notation and contains two primary parts: the network prefix and the host number. IPv4 addresses are bit numbers that are typically displayed in dotted decimal notation. A bit address contains two primary parts: the network prefix and the host number. All hosts within a single network share the same network address.
Networking Basics: What is IPv4 Subnetting?
IP address is an address having information about how to reach a specific host, especially outside the LAN. An IP address is a 32 bit unique address having an address space of 2 Generally, there are two notations in which IP address is written, dotted decimal notation and hexadecimal notation. Dotted Decimal Notation:. Hexadecimal Notation:. Classful Addressing The 32 bit IP address is divided into five sub-classes. These are:.
One of the reasons this happens is that one has to perform mental calculations in decimal and also binary. Another reason is that many people have not had enough practice with subnetting. In this article, we will discuss what Subnetting is, why it came about, its usefulness, and how to do subnetting the proper way. To make this article as practical as possible, we will go through many examples. The same concepts explained here can be applied to IPv6. Moreover, subnetting in IPv6 is more of a want rather than a necessity because of the large address space.
An IP address internet protocol address is a numerical representation that uniquely identifies a specific interface on the network. Addresses in IPv4 are bits long. This allows for a maximum of 4,,, 2 32 unique addresses. Addresses in IPv6 are bits, which allows for 3. The total usable address pool of both versions is reduced by various reserved addresses and other considerations. IP addresses are binary numbers but are typically expressed in decimal form IPv4 or hexadecimal form IPv6 to make reading and using them easier for humans. IP stands for Internet Protocol and describes a set of standards and requirements for creating and transmitting data packets, or datagrams, across networks.

IPv4 - Subnetting
A classful network is a network addressing architecture used in the Internet from until the introduction of Classless Inter-Domain Routing in The method divides the IP address space for Internet Protocol version 4 IPv4 into five address classes based on the leading four address bits. Classes A, B, and C provide unicast addresses for networks of three different network sizes.
This tutorial explains Subnetting step by step with examples. In Subnetting we create multiple small manageable networks from a single large IP network. To best utilize available addresses if we put more than hosts in a single network, due to broadcast and collision, that network will never work. If we put less hosts then remaining addresses will be wasted.
Each IP class is equipped with its own default subnet mask which bounds that IP class to have prefixed number of Networks and prefixed number of Hosts per network.
