What Is DNS And Its Function?

The main function of DNS is to translate domain names into IP Addresses, which computers can understand.

It also provides a list of mail servers which accept Emails for each domain name.

Each domain name in DNS will nominate a set of name servers to be authoritative for its DNS records.

What is DNS and its purpose?

Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.

How does a DNS work?

The Domain Name System (DNS) is the phonebook of the Internet. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources. Each device connected to the Internet has a unique IP address which other machines use to find the device.

Why do we use DNS?

DNS (Domain Name Server) is mainly used to convert human meaningful name (domain name) to computer meaningful name (IP address) in Internet. It allows you to use internet more easily by allowing you to specify a meaningful name on your web browser instead of using IP address.

Is DNS a protocol?

(Although many people think “DNS” stands for “Domain Name Server,” it really stands for “Domain Name System.”) DNS is a protocol within the set of standards for how computers exchange data on the internet and on many private networks, known as the TCP/IP protocol suite.

What is DNS and its types?

What are the different types of DNS server? All DNS servers fall into one of four categories: Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers.

What layer is DNS?

In OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit “below” HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.
