When multiple networks are connected to the Internet the traditional classified addressing scheme could cause you to run out of IP addresses.

The usual way of assigning IP addresses uses the prefixes of 8, 16, or 24 bits. Using prefixes of 13 to 27 bits an address includes the standard 32-bit IP address and adds information on how many bits are used for the network prefix. In the IP address 206.203.1.35/27, the “/27” indicates that the first 27 bits are used to identify the unique network, and the remaining bits are used to identify the specific host.
