- Classless Inter-Domain Routing - Wikipedia
Classless Inter-Domain Routing (CIDR ˈ s aɪ d ər, ˈ s ɪ- ) is a method for allocating IP addresses for IP routing The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet

CIDR stands for Classless Inter-Domain Routing, and refers to the standard of dividing the entire IP address space into smaller networks of variable size

A CIDR block is a collection of IP addresses that share the same network prefix and number of bits A large block consists of more IP addresses and a small suffix The Internet Assigned Numbers Authority (IANA) assigns large CIDR blocks to regional internet registries (RIR)

Classful addressing has been largely replaced by classless inter-domain routing (CIDR), which allows for more flexible allocation of IP addresses by using variable-length subnet masks (VLSM)
- What Is CIDR? Subnets and CIDR Explained - Enterprise Networking Planet
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
