Executive Summary The acronym subnet refers to sub - networking. This is the process of logically dividing an IP network into various divisions or sections within a network. Therefore, sub-netting is the technique and practice of dividing a network into two or more logical networks (Narten, Nordmark, Simpson & Soliman 2007). Within a subnet, all computers connected to it are identifiable by their almost identical IP addresses. The use of IP addresses is in order to identify uniquely computers in a subnet by the use of a router or network IP prefix followed by a host or rest field identifier. This IP address composition makes it easy to trace the network within which the sub network is located. Additionally, the second part helps identify the computer on the host sub network. Normally the expression of the network or routing prefix is in a CIDR notation. This is whereby it is annotated as the first address within the network, followed by the slash character, and then ending in the form of the bit - length of the IP prefix. An example of this case would be such as the IPv4 address - 192.168.10.0/24, which is a prefix of the IP address. From it, we get to know that the first IP address in the network is 192.168.10.0 and that it has 24 bits for the network prefix allocated to it. The remaining 8 bits of the 32 are reserved for the host sub network addressing. It must be noted that the network or data traffic between all sub networks of a network are channeled via routers which act as gateways, as well as the logical boundaries, between the various sub networks within the entire network (Singh, Beebee, & Nordmark 2010)..
Advantages of Sub-netting There are various benefits that sub-netting has. The first benefit is the efficient allocation of IP addresses. This can be achieved through the use of DHCP (Dynamic Host Control Protocol) in the various sub networks to dynamically handle all address allocation to all
