When DNS receives data from the computer named as ‘Peter’, it translates the computer name in to its IP address so that it can be recognized by routers and switches. Likewise, switches and routers recognize number based IP addresses for example, 192.168.0.1 ("What is DNS?” 2005). Moreover, while accessing Internet, or opening any website, humans need to know only the Uniform Resource Location (URL) i.e. the website address ‘www.hotmail.com’. This is a convenient way for humans of accessing the website with the URL instead of its IP address. DNS is a mechanism that converts these web based addresses in to IP address. Consequently, the expediency for humans of accessing IP address based systems via easy names is handled by the DNS server. DNS server is configured separately for this specific function in organizations.
A typical DNS server requires configuration of critical components in order to work correctly. One of these components is the Resource Records (RRs) (Davidowicz, 1999) as these records are configured to handle several tasks including the translation of URL’s in to IP addresses, identification of host and host names i.e. the web server on which the website is hosted and processes associated with mail exchange functions.
DNS logical architecture resembles a tree structure that works from top to bottom along with branches that are called leaves i.e. every single branch represents a leave (Davidowicz, 1999). Likewise, the main branch also called as node from where the tree originates extends from top to bottom represents the root. Nodes can be represented as .org, .com, .ws etc. identifies label of the website. If the length of the website is long there will are more branches and nodes associated with it. Likewise, while considering a URL from a DNS structure representing tree, labels are selected from the direction i.e. from left to the right. In the current information age,
