Description:
The paper explains that DNS is a database system that connects significant names, professionally referred to as host names, to a particular IP address. The paper highlights the significance of DNS by discussing how other processes and applications rely on the services DNS provides, including e-mail, the World Wide Web (WWW), and supplementary applications, such as instant messaging, multi-tier Web applications built by using middleware or an application server, databases, peer-to-peer sharing programs and multiplayer games. The paper notes that any application that connects two or more hosts to share information through the Internet is almost certainly, in one way or another, depending on DNS services.
From the Paper:
"DNS which is an ellipsis for the terms Domain Name System is a database system that enhances the translation a computer's completely qualified domain name into an IP address. For simpler understanding DNS can be defined as a database system that connects significant names, professionally referred to as host names, such as http://www.yahoomail.com, to a particular IP address, such as 192.182.154.7. Simply linking addresses to names is just the start, still, since DNS has many more features over and above host-name-to-address mapping. The main features of host name to IP mapping include storing of mappings of addresses to names and vice versa in a database; distribution of the DNS database; and storing of additional records."Even though DNS is a database, most outstandingly it's a strewn database since every DNS server has only a small fraction of the host name to IP address mappings which is relative to the number of records for the whole Internet. Each DNS server is configured with a unique record that indicates to the DNS server where it will carry out a search for records it doesn't have in its portion of the DNS database which is the IP address of another DNS server. Because of this arrangement in operation, each DNS server sustains only a small fraction of the total DNS host to IP address mappings. The other name for the collection of host-name-to-IP-address mappings contained with the DNS database is a namespace. In effect, when searching a name in DNS, the DNS client first verifies a top-level DNS server database."
