what is Class full addressing and CIDR?

Question

Chitra S · Accepted Answer

Classful addressing is an architecture which divides the IP address into classes based on the fixed number of blocks assigned to the host ID and the network ID.

CIDR stands for Classless Inter-Domain Routing which is a method for allocating and routing IP addresses that replaced the outdated classful system.It uses variable length subnet masks to divide IP address blocks into smaller variable-sized networks(subnets)reducing address wastage.

Classful IP addressing is an outdated architecture that divides IP addressses into five classes(A,B,C,D and E)based on their first few bits determining the network and host portions of the address.CIDR stands for Classless Inter-Domain Routing which is a method for allocating and routing IP addresses that replaced the outdated classful system.It uses variable length subnet masks to divide IP address blocks into smaller variable-sized networks(subnets)reducing address wastage.
