Not IPV for an IPV six.
Hello, everyone.
Today we're going to talk about not and pretty much what it is and what it is used for.
So not pretty much is a mechanism that makes the traffic from a private network to becoming just a single
vital Internet address, but not to everywhere.
And so, in the most simple words, not is basically the service which effectively hides the private
addresses from the Internet.
So, yes, some of the addresses are actually private and they're used by different devices.
So, for example, if you want your network to use multiple IP addresses, you can locally use multiple
private IP addresses and connect the Internet by only a single IP address.
In that way, you are saving quite a lot of public IP addresses that you actually don't need to use
because in your private network you can pretty much choose any IP address for any device.
So, for example, if you're a company and you have a lot, a lot, a lot of machines in your seat,
this doesn't mean that you need to have public IP addresses for all of them.
Instead, you can hear for all of your machines, different local or private IP addresses and only one
public IP addresses, which will connect all these machines to Internet.
So in terms of that, there are two types of the nut operations.
The first one is static, where a private IP address is always translated to the same public IP address.
And by doing this, you, your host within the network, will be visible in Internet.
There were social economic way where a router is assigned to different IP addresses.
So each private IP address is mapped using only one of the IP addresses or the router that has been
assigned to it.
And when doing that, it is actually very important when using the service to have an increased security
because we need to make it difficult for external host to enter the network through the public IP address.
For example, you wouldn't want somebody to assess your IP address and consequently your devices tend
to login into your mushiness through Internet.
Now let's talk about the different IP types and we're going to start by IP reform.
So IP before the basic idea behind it is to allow computers to connect to Internet regardless why device,
what device we use.
So basically each device that is connected to Internet gets a unique code that can be used to receive
data from our connections.
The IP protocol pretty much consists of 32 bits lens, which means that we have access with the IP before
to over four point three billion IP addresses out there.
And as we said, the IP before is already to its maximum capacity.
So all of those IP addresses, all of these numbers have already been reached.
So usually the IP addresses from the IP before consist normally of four groups of eight bits.
Eight bits means that there are 256 possible numbers for each position.
For each of those four positions, you have 256 possible numbers.
And this is how actually we're calculating how many IP before IP addresses are.
You just need to multiply 256, four times.
So 256 multiplied by 256, multiplied by 256, multiplied by 256.
And you get some number around four point three billion.
So according the rules for obtaining the IP before their few classes, that arranging different IP addresses
Class A, Class B, class C, class duties, which is the multicast, and also Class E, which is the
experimental class.
So the multicast and the experimental IP addresses usually cannot be used as a source of addresses.
So we cannot usually use this Halverson's because they are already in use.
We normally have the IP address is zero point zero point zero point zero as an identifier of the IP
before and 127 Doderer.
Zero zero US identifier of the physical complex over the network.
And also, we have the two hundred fifty five zero zero zero, which basically identifies the broadcast
overseas, so we can also not choose just once.
Now, what is IPV six and what is the use for it and what is the need for it?
Well, basically, the IPV six consists of arsenate and with the eight bits, which is way more numbers
comparing to IP before.
And we created this space with IP addresses simply because we run out of IP addresses over the Web.
So we wanted to ensure that we have the space and the IPV six addresses are nowhere near to getting
expired because there are so many of them that we'll never be able to reach.
They basically consist of aid groups of 16 bits.
And as you can see, an example of IPV six Andrius, you can see that 16 bits means that this aid groups
can include not only numbers, but also letters which increase further the number of possible IP addresses.
For example, if we go now to the terminal, we can actually check that.
Let's exit here and then I will write you config.
And if you take a look here, you can see that in the Ethernet sorry, in the eye net or the Internet,
we can see an example of the IPV six outrace.
And you can see in Init six, which is saying to us that is IPV six format of outrace and you can see
all the letters.
So this is actually an IP address.
And for example, if the most of the IP address is IP before you can actually see that here we get it
in that format.
So you can make the difference between the IPV six, which is this type of galleries, and Iku four,
which is the type of IP address.
And if you want to take a look at your computer, you can definitely do it with the IF config command,
which will basically show you all the IP addresses on all the devices connected to your computer that
say.
Guys, thanks very much for watching that video.
I hope now you're pretty clear about how your computer connects to Internet and how our devices are
basically connected to your computer.
That's it.
Thank you very much for watching and I'll see you in the next video.
