What is DNS, and how does it work
Friends, What is DNS, how does it work who created DNS, and what is the DNS record If not, read this blog post to the end, where we give you complete information about DNS.
Today we can access the internet very easily, we can open any website in our Browser, and we can remember the names of almost all the websites of our business, all this became possible only because of DNS, without DNS you can use modern you cannot access the internet and cannot search your favourite websites.
We use DNS every day in our daily life but very few people have enough knowledge about DNS. If you have little understanding of technology, you should know that computers do not understand human language, they can only understand numbers.
When you search the browser to open a website or a web page on the internet, then to understand your request, the computer needs a number called IP address and DNS is the IP address of the website you searched for. He turns to the computer and explains to him.
Read the article to the end to get complete information about DNS, so without any delay, let's start today's article and find out what DNS is in detail.
|What is DNS, and how does it work.|
Full name of DNS
The full name of DNS is the domain name system.
- Full form DNS in English-domain name system.
What is DNS
"DNS is a system used in the internet that converts domain name into IP addresses."Only through DNS, we can connect to this site by searching for the domain name of any website in the web browser as we wish and we can access the website.
All devices using the internet have their unique IP address, which is in the form of a number such as (220.127.116.11). This IP address is machine-readable. But a person cannot remember the IP address of all websites that are on the internet, hence the domain name was created. Domain names are in the form of words that humans can remember.
When a user searches for any domain name in his browser, DNS converts the domain name written in words into an IP address, and then, understanding the IP address of the computer, the website appears on the browser in front of the user.
Simply put, DNS is a system that translates domain names into IP addresses understandable by computers.
History of DNS
The domain name system (DNS) was invented by the American computer scientist Paul Mockapetris in 1980. When the internet started, many websites did not exist on the internet, so any website could only be accessed through an IP address.
But gradually the internet developed and its volume also increased, so many sites were created on the internet that it became impossible to remember an IP address, and DNS was started given these problems. With the advent of DNS, the user was able to access the website of his choice.
how DNS does work
If you still don't understand what DNS is well, understand DNS performance. As we told you above, everything connected to the internet such as a website, computer, servers, smartphone, etc. all have a unique IP address. Only this IP address identifies each device for communication over the World Wide Web.
Since IP addresses are in the form of numbers, it is difficult for an ordinary man to remember them. To solve this problem, memorable domain names for humans have been created. But the devices understand only the IP address, so a translator was needed who could convert the domain name to an IP address and explain this to the devices. This translator is called DNS.
When a user searches for any domain name in his browser (such as www.example.com), DNS converts this domain name to an IP address.
By understanding the IP address of the computer, it detects the website that the user wants to access and connects the IP address to the server hosting this site. After that, a site is opened www.example.com in the user's browser and the user can access it.
You can understand DNS like the phonebook of the internet because it works like the phonebook of your mobile phone. Just as you save all contact numbers in your phonebook by name and to call or send a message to a number, remember the name instead of the number and look up the name in the phonebook too, similarly any website on the internet to access the domain name is remembered instead of the IP address. So DNS does something like this.
What is a record DNS
After understanding what DNS is, let's now understand DNS logs as well. The domain name and IP address information are systematically contained with DNS called a DNS log. DNS records can be of many types such as A, AAAA, MX, TXT, CNAME, etc., and the work of all these types is also different.
- A Record – Translates to the named domain IPv4.
- AAAA Record – Translates to the named domain IPv6.
- CNAME Record – The full name of CNAME is the canonical name register. Assigns a nickname called a real or specific domain.
- MX Record – Specifies the mail server associated with the Mail Exchange log domain.
- TXT Record – The full name of TXT is a text record. It is used in many tasks, such as domain ownership, domain protection from spam, etc.
