Classless Inter Domain Routing (CIDR)

This lesson discusses Classless Inter Domain Routing (CIDR). CIDR allows us to have variable-length subnet masks. Subnet masks within CIDR are not within the standard classes of A,B or C and CIDR notation is used when standard subnet masks do not work and allows us to break up subnet masks and work with IP addresses.
