What is domain name server and how it works


The Internet's DNS system works much like a phone book by managing the mapping between names and numbers. DNS servers translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser. These requests are called queries.

What are the 3 types of DNS?

There are three main kinds of DNS Servers — primary servers, secondary servers, and caching servers.

What is domain server example?

For example, when a Web address (URL) is typed into a browser, a DNS query is made to learn an IP address of a Web server associated with that name. Using the www.example.com URL, example.com is the domain name, and www is the hostname. DNS resolution maps www.example.com into an IP address (such as 192.0. 2.1).

What is the purpose of DNS server?

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.

What does domain server mean?

Server. A domain is group of nodes, workstations, devices and other servers, etc that are meant to share resources and data. A server itself is often a part of a domain along with other clients and servers. These may be devices, computers, programs, etc.
