The IP addressing scheme that was created for IPv4 comprises 32 bits that were allotted for assigning IP addresses. The exponential growth in the number of computers getting connected to the Internet resulted in problems related to address space exhaustion and management of routing tables. Methods that can be used to make optimum utilization of the existing address space had to be created. Two such commonly used methods are subnetting and supernetting. Supernetting is also referred to as Classless Inter-Domain Routing. In subnetting, a single public IP address is further divided into multiple networks called subnets.
