Subnetting is applicable to IP addresses since it is done by borrowing bits from the IP address’s host section. In a sense, the IP address includes three parts: the network part, the subnet part, and the host part.

CIDR, or Classless Inter Domain Routing, allows you to borrow bits from the Host part of an IP address and use them as Network in Network, or Subnet. Subnetting allows a single Class A IP address to be used to create smaller sub-networks, which improves network administration capabilities.
