It is database or system that stores the name of every domain online. The database of DNS comprises the name of domain and website host that are then translated into an internet protocol i.e. IP address. This DNS can be a type of dictionary or a phone book that comprises Web IP addresses.

The web addresses or URL’s get translated into an IP address that can be contacted in order to reach certain website. It helps in the connection with selected website with the help of DNS. This task is accomplished by this tool by a conversion of the website name in a particular browser to a pre-determined IP address.

How it works?

It is a protocol that is within the standards set for the computers for exchanging the data on the internet and also on private networks. This is known as a TCP/IP protocol suite for internet. The basic job is to turn the domain name that is user friendly similar to “howstuffworks.com” where the IP addresses are used to identify computers on the network. It is also similar to the computer GPS for the internet. The IP addresses are used to reach the site of the user’s request. This helps to get connected to the own address book. This is very much similar to dialing a phone that is to get connected to the person you is trying to call. It manages massive database where it maps the domain names to the IP addresses.

DNS is used by the computer to look up the easy access of the websites that are to be searched. The apt name would be ‘DNS name resolution’ that helps to resolve the IP addresses and its domain name. The DNS look up will bypass directly to the browser. In addition to this the IP addresses change from time to time and also get associated with multiple addresses with a single name of the domain. When the DNS servers are connected to the home networks, ISP or any other Wi-Fi network then the router sends some important configuration of the networks.


It is definitely a key component of the internet. There are two approaches for the DNS lookups :

  • The Forward or normal DNS lookup
  • The Reverse DNS lookup

Forward DNS lookup:

It is a simple and most common DNS lookup that simplifies to find the IP addresses of the domain. It is easy to remember the domain name. It provides a way to communicate with other in a unique way. The following the steps for the DNS resolution:

  • The user has to enter the domain name in to their internet browser.
  •  The computer will send this domain name as a DNS request to the user’s ISP.
  • The ISP determines the IP address that is associated with the name.
  • This request will be forwarded as an effort to the located the DNS record that consists of the data.
  • The IP address of the domain is returned to the user if once the record is found.
  • This facilitates the easy communication of the computer with the server.

Reverse DNS approach:

The reverse DNS lookup also follows the same steps except it starts with an IP address and returns with the domain name. It takes a while when the DNS is unable to connect to the IP address or domain name. It is commonly referred as a DNS or a reverse DNS that is involved in the identification of IP address. The DNS can be used to track the website owners. This DNS is used to stop the email spam and other privacy issues. The DNS processes are authenticated and are only for the purpose of monitoring.

It is just one side of the processes in DNS. The main function is to translate the addresses of the websites in numeric form to the domain host names. It locates that the domain host name belongs to IP address. This process can be accessed just with the IP address.
