Download file to see previous pages An IP address refers to a 32-bit group of numbers pointing to a particular location of a system in a network. These numbers are arranged in a group of four digits represented either by 1 or 0. In order for a host to connect to a certain system, it needs to recognize the IP address of that system.

Transmission Control Protocol is a communication channel between two applications. An application seeking to communicate with another application initiates the process by sending a communication request (Azad, 2008). Once confirmed a full-duplex communication is built between the two apps and remains so until one application decides to terminate it through a communication line.

TCP and IP work together to enable full integration between the application softwares such as browsers and network softwares. While the TCP is responsible for fragmenting data into IP packets before they are sent, IP sents the data and is retrieved by the TCP at the destination end (Gollmann, 2011).

The Domain Name System is the internet facility that resolves the IP network addresses to their subsequent physical computer systems. Abbreviated as DNS, it is responsible for resolving hostnames into Internet Protocol address for each computer system and therefore its security or lack of it poses serious challenges to the integrity of data in an organization (John E. Tucker, 2011).

Having learned that the role of DNS is to resolve IP addresses the question arises as to the origin of these 32-digit numbers. Considering a company with a massive number of computers it would be naturally impractical to physically assign IP addresses to every system. The Dynamic Host Configuration Protocol is therefore the network protocol that allots IP addresses to each computer following a pre-defined range of numbers available for a certain network.

The booting of a system automatically initiates DHCP to assign IP addresses to each computer system. This is achieved through a series of steps (Vacca, 2006) . A broadcast request known as DCHPDISCOVER is sent to locate a DCHP server and the router act as an intermediary to direct the request to the correct server. ...Download file to see next pages Read More
