CIDR - Classless Inter Domain Routing

CIDR was a technique introduced in the 1990s which was designed to reduce the consumption rate of IPv4 addressing, whilst helping to keep routing table sizes minimal. The system replaced the classful addressing system which was originally used to allocate IPv4 addresses. Instead, CIDR permits a variable length network ID, ensuring that end networks receive a network prefix appropriate to their size.
