CIDR
(Classless Inter-Domain Routing)
Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and routing internet traffic more efficiently. CIDR replaces the older class-based system with a flexible, variable-length subnet masking (VLSM) approach.
CIDR notation represents IP addresses with a prefix, such as 192.168.1.0/24, where the number after the slash indicates the network size. This allows for more precise allocation of IP addresses and reduces routing table sizes. CIDR is a fundamental concept in modern networking and is essential for managing IP address space in large networks.
