The Concept of IP Subnetting
IP stands for Internet Protocol, whose address is a figure that distinctively categorizes a computer on a Transfer Control Protocol/Internet Protocol (TCP/IP) network. The IP network makes it possible for packets to be addressed to this computer. Subnetting can be defined as the system of subdividing an existing physical network into numerous but smaller logical networks known as subnets. A subnet can be divided into smaller subnets, in a process that involves shifting the subnet mask of the local network number to generate an even number of smaller network numbers, all of which have the matching range of IP addresses.
Subnetting provides several advantages. It facilitates network management, for example, it keeps the routing tables short and makes troubleshooting easier. Subnetting when used in combination with a switch reduces the network traffic by decreasing the number of broadcasts. Subnetting can increase the capabilities of a LAN, for example by increasing the number of allowed hosts in the LAN.
On the other hand, unlike subnetting, supernetting entails merging two or more blocks of IP addresses which form an unremitting variety of addresses, a supernet is formed when one has a need to place extra hosts on a single network than currently will work in a classful configuration. Although supernetting provides bigger single networks, it does not present more IP addresses. What is encompassed in Public and Private TCP/IP addresses? An IP (Internet Protocol) address is a number that uniquely identifies a computer on a TCP/IP-based network and enables packets can be addressed to this computer. It consists of four decimal numbers separated by dots; each number represents a four-bit binary number (octet).
Private IP addresses are addresses that are not routable on the public Internet. They are meant for devices that are connected behind a router, proxy server, or another such device. There are two main applications for private IP addresses. To start with, they may be used for purposes of concealing the systems of an organization. This way, the public does not get to view the contents of the organization. In addition, IP addresses could also find a use for purposes of distributing the existing network of an organization. Public IP addresses are a term used in reference to those IP addresses which can be readily accessed by members of the public. They permit other people to have access to one’s computer even through different computers. Public IP Addresses are also referred to as static IP addresses.
