The process of subnetting involves dividing a network up into smaller networks called subnets or sub networks. Each of these subnets has its own specific address. To create these additional networks we use a subnet mask. The subnet mask simply determines which portion of the IP address belongs to the host. The subnet address is created by dividing the host address into network address and host address.

Internet protocol Version 4 (IPv4): Internet protocol is glue that holds the internet together. It transfers the datagrams from source to destination without considering that whether the machines are on the same network or not. IP is the main transport mechanism used by TCP/IP suit of protocols. IP provides connectionless, unreliable services.

In order to provide computer to computer communication via Internet, we need a global addressing scheme. Such an addressing is provided by Internet Protocol (IP) at the network layer.

• IP addressing supports five different address classes: A, B, C, D and E. Only classes A, Band C are available for commercial use.

• We can find the class of an address when given the address in binary notation or dotted decimal notation.

• The fast growth of Internet led to the near depletion of the available addresses.

• We have run out of class A and B addresses, and a class C block is too small for most midsize organizations.

• To overcome the problem of address depletion and give more organizations access to internet, classess addressing was designed and implemented.

The Internet's basic protocol called IP for Internet Protocol. The objective of starting this protocol is assigned to interconnect networks do not have the same frame-level protocols or package level. The internet acronym comes from inter-networking and corresponds to an interconnection fashion: each independent network must transport in the weft or in the data area of the packet an IP packet, as shown in Figure.

IPV6 is also known as IPng (Internetworking Protocol, next generation). The numbers of users of the internet are increasing day by day and the services offered to these users are also increasing. A huge number of addresses are needed to accommodate such vast number of hosts. The internet not only transmits textual data. It also allows us to transmit audio and video data. In such data, the high speed data transfer is desired. Internet working protocol version 6 (IPv6) was developed to overcome the shortcomings of IPv4.

An IP address is equivalent to your postal address and just like the mail service, each computer has an address so that it will only receive the information that is send by someone else.

In a local area network (LAN) or other network, the MAC (Media Access Control) address is your computer's unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.)

• Supernetting is an addressing scheme in which several class C blocks can be combined to create a larger range of addresses.

• In other words, several networks are combined to create a supernetwork or a supernet.
