DNS stands for Domain Name System and it is also known as Name Server. A DNS server is a computer server and it contains a database of public IP addresses. So, it’s the phone book of the Internet. The main purpose of a DNS server is to resolve or translate domain names to IP addresses accordingly. A DNS server is run by special software and communicates with each other using special protocols.
Purpose Of DNS Server
When we visit a website, we type the domain name on the browser. This is because remembering a domain name or hostname is much easier than remembering the website’s IP address number, 103.77.188.18. Typing the domain name might be easy for us but computers and network devices don’t recognize domain names when they try to locate each other on the internet. Therefore, it is much more convenient and precise to use an IP address to locate the domain name. So, the DNS server is the numerical representation of what server on the internet the website resides on.
Working Procedure Of A DNS Server
The working procedure of a DNS server is a bit complicated. When you type the domain name on the browser’s address bar and press Enter, the DNS server sends some DNS queries to several servers to find the address that you want to visit. Each query translates a different part of the domain name you entered. There are few servers available that complete the process. They are –
1. A DNS Resolver: This server receives the request to resolve the domain name with the IP address. Then, this server finds out the location of the website on the internet that you want to visit.
2. A Root Server: This server receives the first request, and sends the result of the query to the DNS resolver. The Root server lets the DNS Resolver know the address of the Top-Level Domain (TLD) server and where it is located.
3. A TLD Server: Next, the DNS resolver sends queries to the TLD server. The TLD server then returns the information of the Authoritative Name Server where the site is actually returned.
4. An Authoritative Name Server: In the last step, the DNS Resolver sends queries to learn the actual IP address of the website that you want to visit. Once the IP address is returned, the website that you want to visit will be displayed on your browser.
How To Obtain Internet Server Information
You can easily get the internet server information. You can use the nslookup command to query the DNS server on Windows PCs. First, open the Command Prompt tool and then type the following:
nslookup website name
This command will return the following information:
Name: Website Name
Addresses: 151.101.2.114
151.101.66.114
151.101.130.114
151.101.194.114
