Since we are working with a 32-bit IPv4 address, that leaves 12 bits left to indicate how many hosts can connect to the IP address. This quickly tells you that the network prefix is 192.168.127.0 and there are 20 bits in the network prefix. CIDR notation can drop trailing zeroes at the end of an address. Here is an example of how CIDR notation writes an IP address with its respective subnet mask:ĬIDR notation is sometimes called slash notation because of the use of a slash (e.g., /20) to indicate where the network prefix ends and the host numbers start. With the creation of CIDR also came CIDR notation, which is a simpler way to write an IP address that also contains how many bits are in its subnet mask. To do this, you strategically borrow bits from the network prefix in the IP address to create the summarization. This process could summarize an organization’s routing with one IP address, called route summarization. CIDR uses subnetting to divide up a single network, but it can also create a supernet of those subnets. ![]() One of the main advantages of CIDR is the ability to create supernets.

This process, called variable-length subnet masking (VLSM), lets IP addresses divide into subnetworks (subnets) all with the same network identifier, but each subnet contains a different number of hosts able to connect to that IP address. Each IP address has a specific number of bits in the network prefix and host number that says how many hosts are in that specific class.Īfter 1993, the introduction of CIDR bypassed the need for classes since subnet masks were able to split up the three main classes. The three main classes are Class A, Class B, and Class C. ![]() Before 1993, a set of IP classes determined the routing protocol, leading to the fast consumption of IPv4 addresses because of the inefficiency of the routing protocol. ![]() Classless inter-domain routing (CIDR) is a method of internet protocol (IP) addressing by using subnetting and subnet masks to segregate classful IP addresses. ![]()
