Meaning and Principles of DNS


The Domain name system is the full form of DNS. Domain name system is linked to the internet and focuses on a system using the Internet Protocol ( IP). The servers of the DNS are required for the working of DNS. The IP address is being calculated with the aid of a lookup table. As it is very common, we all have an idea that each computer system or website has its own unique IP address which is a very lengthy digital code. DNS is considered an IP service that is used to translate the name of any domain into an individual IP address. DNS is alphabetic and thus it is convenient and straightforward which is helpful. 

History of the DNS

After knowing about the DNS’s full form and meaning, let us now proceed toward the history of DNS. The service was created in the year 1983, and it became a part of the original Internet Standards in the year 1986. Two documents that marked the start of the service are known as RFC 1034 and RFC 1035. Since then, it has undergone different types of updates in its lifetime.

Types of DNS 

Next, let us have a look at the different types of the DNS acronym. There are two kinds of DNS. These are Authoritative DNS and Recursive DNS.  Both types are quite important as they have separate uses or applications.

Mode of working of the DNS

The service having DNS full form works with the help of DNS servers. At first, the user has to enter the domain name into the web browser. This sends a request to the DNS server. The server attempts to find the IP address through a look-up table. After finding the essential pieces of information, it sends these to the user's web browser through the correct servers.

 

It is also crucial to know that the system having DNS full meaning also has its own network. If a DNS server cannot find the IP address then it will ask others until the mission is reached. This makes the process extremely accurate and dependable.

Working Principles of DNS

DNS is very important and essential because the domain names are very easy to remember for people, sites, computers or devices and are accessed based on the IP addresses. The working in the DNS is processed with the help of the servers of DNS. When a domain name is entered by any user into a web browser, the supplication goes to the DNS server. By using a lookup table, the DNS server decides the IP address. Then it transmitted the information supplied to the user’s web browser through the genuine servers.


The information from all the website domain servers which is present on the internet is collected and kept at the Central Registry. For obtaining the updated DNS data, the Host companies and service providers regularly interact with the Central Registry. Your Internet Service Provider will have a look at the DNS which is associated with the domain name when you will type in a web address, then translate it into an IP address which is machine learning and then direct your Internet connection to the correct and proper website. Usually, it used to 


take around 12-36 hours for the servers of the domain name which has to be updated worldwide and to be able to obtain the data after you will register for a new domain name or when during the updating of the DNS servers on your domain name. These 36 hours are known as propagation.

Features of the DNS service

Several features have led to the success of the service having DNS. Some of these are:

  1. Ability to store several records

  2. Power to control all applications that use the internet.

  3. Use of a distributed database.

  4. Contains record types that help in the usage of other applications.

Important Features of the DNS

There are a number of features which is responsible for the success of DNS and some of them are given below.

  • A DNS consists of a database that is distributed. 

  • Additional lists of the data are also being reserved within the database of DNS.

  • The server of DNS offers a user interface and very excellent features. A considerable quantity of any DNS needs to be managed through the interface of users. 

Advantages of DNS 

There are several advantages of the service having DNS full meaning. These are:

  1. Automatically correct typing errors if present. 

  2. Messages are delivered to the user at a very fast rate.

  3. Requests are answered by the closest node.

  4. This in turn helps to save time.

  5. The users receive the important messages with downtime of zero.

  6. Through casting any technology, taking an example of maintenance or downtime, the supplications are being answered by the nearest node.

Disadvantages of DNS

ICANN is able to control the DNS root registry which is one of the private non-profit organizations (NPO) which connects to any particular country and the difficulties in the abstract idea of network neutrality.


The collapse of DNS can even destroy the World Wide Web, and even if there are more than one root server and backup servers and which will going to cause immense harm at the different locations that the DNS servers have decided.

Conclusion

It is evident from above that the term DNS stands for Domain Name System. You will also be able to understand from the above sections that the DNS plays an extremely important role in maintaining the proper functioning of the internet. Thus, it is very important for modern man.

FAQs on DNS Full Form

1. What is a Domain Name?

A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. For example, the DNS Made Easy organization has a domain called dnsmadeeasy.com.

2. What is an IP?

The term IP stands for Internet Protocol. It is the method by which data moves across the internet. Each computer has its own unique IP address that separates it from the other computers that are present on the server. An Internet Protocol address is a numerical label assigned to each device connected to a computer network. An IP address has two main functions: host or network interface identification and location addressing.

3. Is a DNS Zone the Same as a DNS Domain?

A "domain" represents the entire set of names/machines that are contained under an organizational domain name. For example, all domain names ending with ".com" are part of the "com" domain. Domains are broken into zones for which individual DNS servers are responsible.
