Specifically, we will be covering network classes, subnets, and CIDR notation for grouping IP addresses. Every location or device on a network must be addressable. This means that it can be reached by referencing its designation under a predefined system of addresses.

CIDR (Classless Inter-Domain Routing or supernetting) is a method of assigning IP addresses that improves the efficiency of address distribution and replaces the previous system based on Class A, Class B and Class C networks.
7 lis 2023 · Classless Inter-Domain Routing (CIDR) is a method of IP address allocation and IP routing that allows for more efficient use of IP addresses. CIDR is based on the idea that IP addresses can be allocated and routed based on their network prefix rather than their class, which was the traditional way of IP address allocation.
5 lis 2024 · Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and routing that replaces the old system based on classes A, B, and C. Introduced in 1993, CIDR allows for more efficient allocation of IP addresses by allowing variable-length subnet masks, effectively eliminating the rigid structure of classful addressing.
17 mar 2023 · Classless Inter-Domain Routing (CIDR) is an IP addressing system that replaced the previous system of using Class A, B, and C networks. CIDR was developed to help alleviate the shortage of available IP addresses by allowing more efficient address allocation using more unique and granular identifiers for networks and individual devices.
Because CIDR by definition isn't bound by class, it can organize IP addresses into subnets. This means it performs the task of subnetting, which saves a lot of IP addresses. CIDR makes networks more efficient and helps delay the exhaustion of the IPv4 address system. How does CIDR work?
In this article, you have seen what CIDR notation is and how to calculate different parts of a subnet. CIDR notation is widely used in networking to specify IP address ranges for subnets, since it is a more compact form that concisely conveys the necessary details about the subnet.
