CIDR


Short for Classless Inter-Domain Routing, a new IP addressing scheme that replaces the older system based on classes A, B, and C. With CIDR, a single IP address can be used to designate many unique IP addresses. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number, called the IP prefix. For example: 172.200.0.0/16 The IP prefix specifies how many addresses are covered by the CIDR address, with lower numbers covering more addresses. An IP prefix of /12, for example, can be used to address 4,096 former Class C addresses. CIDR addresses reduce the size of routing tables and make more IP addresses available within organizations. CIDR is also called supernetting.
