What is DNS and how does it work?



Today, we will know about DNS which we use every day, but we do not know how it is working. DNS is a mechanism by which a web name is available with an IP.
Then we hit the same IP and collect our required file from that IP
So the problem of remembering our IP has been removed by the DNS, you will load the money on your mobile phone, but you do not say in the shop, "The brother will load 10 rupees on my Gough number (if the amount of money is ten, then the relation will be loaded last) You say the number with the numbers and then they're loading. Here you have your number.
So many such things can be used for IPs. While hosting our web site, I have to know my own IP, but for DDOS ATTACK, the website or the server's IP address can also be used.
So, how do I know the IP address of a site? Suppose I will find the IP address of this site www.wasikur.ooo.
I'm showing two methods

1. Go to your computer's start menu. Write a search for CMD. Then a black CMD box will be OPEN. Write this command there.

Ping www.wasikur.ooo

Then see
Reply from 209.15.20.222: Bytes = 32 time = 291ms TTL = 47

You can get 4 such reply.

See if you are receiving a reply from an IP, this IP is the IP of www.wasikur.ooo.

2. There are some web sites where the web's name shows the IP of the web. Such as
https://www.ultratools.com/tools/ipWhoisLookupResult
Check out this site.
Now come to the DNS how to increase the internet speed.

Basically, it is possible to increase the browsing speed.
Whenever we search something, we're never noticed, in the browser tab, a round first turns anti clockwise, after some seconds it rotates clockwise, why is it ever thought?
Why do the brothers turn around and turn around, behind them, why do they have to go back and look at that time? I do not see the one behind me (all the emotions)
See, here the anti clockwise is rotating because it means that the browser is searching the IP address of your search engine from the DNS server
Turning clockwise, getting the IP through the DNS is going to the browser's IP. Now searching for this IP will be faster than if your internet speed is higher or the internet speed will be too low, depending on it very little depends on it. Depending on the reliability of the DNS server you are using or how much speed you can support. This means that your internet speed is high, but DNS will be less reliable if your search speed decreases because there is no search functionality without IP. Brother, I do not set up the DNS server any day, how do I work? If we have an internet connection that has their own DNS server, it is given as default address. If we do not give it to our Dns server option, in our case we use Google's DNS. Now see if the DNS server you are using is far away from you. If you are using Bangladesh and you are using Singapore as a low trusted DNS server, then see how it will be, first of all, your search will go to Singapore's DNS, in Singapore. It may take some time (maybe a second, or more, or less), because of the DNS low credibility, it will take more time to find the IP address of the search site, calculate these time, you will just have 3-10 seconds to name it against its IP, find the IP Then you have to go to the IP to understand how much time is being snapped?
So what do you do How to speed up ???
Simple Issues If you use any of the reliable DNS servers in Bangladesh, the time of departure is less and the result of being a trusted DNS server is because of the IP address, the clock is not rotating, clock is rotating, or if it is time to look for your IP, You can quickly access your desired site.
I will discuss how to set the next phase.
