What is the Difference Between WHOIS and Domain Name System?

 The DNS and WHOIS are two distinct systems used for managing domain names on the internet. Both systems serve different purposes and work in tandem to ensure the smooth operation of the Internet.

What is WHOIS?

WHOIS is a database of information about registered domain names, their owners, and their administrators. The WHOIS database stores contact information such as the name, address, phone number, and email address of the person or organization that registered the domain name. It also contains information about the domain registrar, the date of registration, and the expiration date of the domain name.


The WHOIS database is used by various parties, such as law enforcement agencies, trademark owners, and internet service providers, to identify the owners of domain names and to resolve disputes related to domain names.

What is DNS?

DNS, on the other hand, is a system that translates domain names into IP addresses. When you enter a domain name into your web browser, DNS translates that domain name into an IP address, which is used to locate the server hosting the website associated with that domain name. This allows you to access the website by typing in the domain name rather than having to remember the IP address of the server.


DNS is essential to the functioning of the internet as we know it today. It ensures that domain names are translated into IP addresses correctly and quickly, allowing users to access websites and other online resources easily.

Differences between WHOIS and DNS

While WHOIS and DNS are both important for managing domain names, they serve different purposes and have some key differences:

1. Information stored: 

The WHOIS database stores information about the registered domain name, its owner, and its administrators. DNS, on the other hand, stores information about the IP address associated with the domain name.

2. Purpose :

The purpose of WHOIS is to provide information about the owner of a domain name and to resolve disputes related to domain names. The purpose of DNS is to translate domain names into IP addresses, allowing users to access websites and other online resources.

3 Access: 

The WHOIS database is publicly accessible, meaning that anyone can search for information about a registered domain name. DNS, on the other hand, is not publicly accessible, and only authorized parties can access and modify the DNS records.

4. Privacy: 

WHOIS information is publicly available, meaning that the owner of a domain name cannot keep their personal information private. DNS information is not publicly available, meaning that the IP address associated with a domain name is not accessible to the public.

In conclusion 

WHOIS and DNS are two essential systems that work together to ensure the smooth operation of the Internet. While they serve different purposes and have some key differences, they are both critical for managing domain names and ensuring that users can access websites and other online resources quickly and easily.
