DNS service, hello, everyone.
Today, we're going to talk about the Genius Service, which is a very important one, and I'm sure
that when they explain it to you, you will understand that you actually see the DNS service in use
every single day.
So you know that every device over the Web has an IP address.
But just think about it.
If we use the IP address as a name of the device, which is usually the case, this name would be really
ugly.
We're not going to be able to remember this name and basically for the users will not be comfortable
because we understand words and letters way better than numbers.
Also, it is way easier to remember a word than random numbers placed together.
And here it comes, the Jeunesse Service.
So the Jeunesse Service is basically used to create a domain name or to screen name that is on the top
of the IP address and basically means that we can refer to the name in order to assess the IP address.
So for that reason, the Jinnah's service is one of the foundations of our network today and it makes
it more available for the normal users that don't need to remember in technical terms or numbers.
So, for example, if we check the IP address of Google dot com, you can see that it's eight point
eight point eight and the non authoritative server of Google is going to be actually 172 to 17 for 206.
But how do we check that?
They were six to one common that you can use in basically every device and this is code in this lookup.
So let's go now to the terminal and let's see how this comment actually works.
So here I am in the terminal from my MacBook in Right Enis Look.
So after was here this morning, as you can see now, we can basically check everything on the Web and
see its IP address, which is quite useful and sometimes quite fun to do.
So just think about some website entries here and you immediately see its IP address.
I would do a website of my desire, for example, related to YouTube dot com.
And if I check here, I can see the exact IP address of YouTube, which is in our case, 170 to 217
470.
Let's try another and let's try, for example, on our famous website.
Let's see, let's see games dot com.
OK, so here you can see that, for example, the games, dot com hiss, quite a lot of IP addresses
associated with actually it has two, six, seven IP addresses associated with games, dot com.
And let's try my website, which is called.
Skilled Army dot com, and you can see that this is actually my IP address, which is a public one,
and you can always check it from the Web.
Let's now try to access an IP address or a website that doesn't exist.
I will just write some random letters.
Dot com, and you can see that service can be found and this is because this website does not exist.
OK, so here we have the server, but the actual credit also the website does not exist because it is
simply not there.
So this is why the database is doing.
For example, if you go to the browser and you write the website there, the VNS pretty much translates
as the name that you wrote into an IP address.
So actually this is the actual numbers of the IP address that is related to this name.
For example, Windows is automatically configured to use the DNS service in order to configure the Internet
service providers.
So the the Dennis providers are actually pretty different.
You can have different DNS providers.
They could be, for example, the open ocean is that Waterer DNS, the Google audience as well.
And for example, if you want to assess the Google DNS, you can exoduses the following link and see
some information about it.
So let's actually do it.
So here for Google and Google and go to the website that they provide you on that slide, which is called
Developers, the dot Google dot com speed, public DNS.
You can actually see the information about the DNS.
You can see an article, what is DNS, whatever the network addresses.
And actually this 888 is exactly the one that we found from the terminal, which is the global server.
And you can actually hear see some codes, information about this.
So I would advise you to see that page and read it, because you can see also guides and support above
the public DNS services provided by Google.
So that's the case.
I think it's enough for today.
Thank you very much for watching.
And I hope you enjoyed the topic related to the DNS.
