What is DNS how it do?

DNS is a commonly heard word for the Internet DNS or Domain Name Server it’s a server system. that acts to convert domain names into IP addresses because indeed The reference to the machine’s location is the computer on the Internet. IP (Internet Protocol) number is a reference to communicate in network, but if people will remember the IP number of various websites. It would be difficult for people recognition skills.

When you register your domain for people to remember or access. what you or the general public Must remember, so there is only a domain name, such as example.com without having to remember the numerical IP address. DNS therefore plays a role in this section. To be the core of referrals, domain names are converted. to an IP address automatically

It’s as if When we look for a phone number on a mobile phone We were able to find the name that we saved in the contact list system. By the system of contacts that we have saved a phone number when we search for a contact name. We can call that person immediately without memorizing the phone number. Yes, DNS works like that.

We can compare DNS to a list of Internet contacts. Instead of matching people to phone numbers, it maps domain names to IP addresses. IP addresses are the language of the Internet. Computers communicate using Internet protocols or IP addresses, which are unique combinations of numbers and letters, such as (IPv4 address) or 2002:0a8:85e3:0000:0000:6a2e:0417:7123. (IPv6 address)

But such long strings of numbers and letters aren’t easy to remember, so DNS maps IP addresses to easily remembered domain names, such as example.com. Let’s sit and look at all those IP addresses. which makes surfing the web more enjoyable.

How does DNS work?
You may have heard of the term DNS query or DNS lookup when looking up information on DNS. This is a common way of referring to how DNS works and directs you to a specific website. But there are a few steps on the way, so we’ll break them down and explain them step by step. Please note that we are going to cover a few technical topics.

Browsing: When initiated by a user typing a domain name such as website.com into the web browser address bar. After you enter your domain The search will start looking for website.com’s IP address so that your browser can display the correct content. The search is initiated by checking the root server to see where to go next.
Root Server : Worldwide there are 13 root servers. And these root servers know all DNS information of every domain. The root server checks that DNS information to determine where to look next: nameservers, TLDs.
Nameserver TLD: TLD or top-level domain. is the last part of a domain name, such as .com in example.com. Some of the most common TLDs are .com, .net, and .org, and some of the most popular country-specific TLDs are .uk, .ca, And every .au TLD has a dedicated TLD nameserver that stores the DNS information for that particular TLD name. website.com The original query needs to check the .com TLD nameservers to find that domain’s nameservers for example.com.

Domain’s nameservers: This is where you’ll find the DNS zone file for example.com, and the zone file is where you’ll find each DNS record. These records, such as A records, MX records, and subdomains can be Can add, edit or delete in the zone file. The original query looks at the domain’s nameservers for an A record for example.com mapped to a unique IP address, which is what our query will use to browse and display content (from website.com’s hosting). website for website.com in your web browser.
