CIDR (Classless Inter-Domain Routing) is a method used to allocate and manage IP addresses more efficiently by allowing for variable-length subnet masking, enabling the aggregation of IP addresses into a single routing table entry.
CIDR Definition: CIDR (Classless Inter-Domain Routing) is a method used to allocate and manage IP addresses more efficiently by allowing for variable-length subnet masking, enabling the aggregation of IP addresses into a single routing table entry.
CIDR, which stands for Classless Inter-Domain Routing, is a methodology used in IP addressing and routing. It allows for more efficient allocation of IP addresses by aggregating them into blocks, which are represented by a single IP address and a prefix length that indicates the number of bits in the block. This enables better utilization of IP address space and more flexible routing.
