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.
CIDR is one of the topics you'll master in the CCNA Boot Camp.
