Classless Inter-Domain Routing is a method for allocating IP addresses and for IP routing. The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet. Its goal was to slow the growth of routing tables on routers across the Internet, and to … See more Each IP address consists of a network-identifying prefix followed by a host identifier. The question is how many bits of the address are in the network prefix, and how many are in the host identifier. In the previous See more CIDR notation is a compact representation of an IP address and its associated network mask. The notation was invented by Phil Karn in the 1980s. CIDR notation specifies an IP … See more CIDR is principally a bitwise, prefix-based standard for the representation of IP addresses and their routing properties. It facilitates routing by allowing blocks of addresses to be … See more • Internet protocol suite See more A subnet mask is a bitmask that encodes the prefix length associated with an IPv4 address or network in quad-dotted notation: 32 bits, … See more CIDR provides fine-grained routing prefix aggregation. For example, if the first 20 bits of their network prefixes match, sixteen contiguous /24 networks can be aggregated and … See more • Classless IN-ADDR.ARPA delegation.

It is an IP address assigning method that improves the efficiency of address distribution. It is also known as supernetting that replaces the older system based on classes A, B, and C networks. By using a single CIDR IP address many unique IP addresses can be designated.
Subnetting using the CIDR method may give different amounts of …
