So let's talk about this subject.
This is also an important topic in our booking and let's talk about first submitting and devoting large
networking to small subnetwork is somebody so we can develop into small sub networks exclusively.
And this subject mask is masking which to define network partnerships.
So if you do it right, particular penthouse, you need to identify the starting network and the wholesale
for that will use the subnet mask and subnet mask helps you to organize different networks neatly.
So if you have different departments and you've got Alexia's and était and giving, maintaining the
large network is very is not nice that you can do it as you see as one subnet, an easy one subnet,
another department as one subnet.
So you can easily manage the subnet.
So let's see the private eye, and so we have discussed the terror mainly with how this crisis, the
ABC and we also discussed the DNA, but we'll see how this progresses on the ABC and this private IP
addresses are not used anywhere on the public.
These are only used for in private networks.
So these IP addresses cannot communicate with ultraworld.
And Glacier.
I experts range from one to one hundred and this and that is the private I put in for the cashier and
the Devadas is covered for a number of networks.
We can create our 136 a number of this money.
So we will look at this, how we got this number in next and come into the Glasby.
We have the prototype screen from 170 to 16, zero zero to 100 to 200 zero zero.
So within this range you can assign these Glaspie IP addresses to your local network computers and the
default subnet mask for Class B IP address when used to refer to zero.
So don't worry about that.
Mask will cover everything in the next room and the number of networks is sixteen thousand and number
six.
Now let's see what ocracy, uh, the private label does when used 100 162000 to 120 to 160.
A tooth for a tooth.
For a tooth.
For a tooth 4.0.
And we can create these really networks and with the number of hospital network are two, three, four.
So, one, you need to give some importance to the class and the class in the car you use it for the
smaller organizations are at least home.
In our homes, we use the currency prior to the threat, even I showed you my IP address, it's one
and two and three.
Because we will see that in the next.
But let's consider the number of hospital networks, so you have one network in your home and you can
maximum said these private IP to two to four hosts.
So in your home, even if you take laptop, mobile phone, smart TV and any other Iot device which connects
to the Internet, that's an IP address which connects to a router.
That's an IP address.
Right.
And you you have like 10 or 20 or 30 devices and 244 four is very large enough to hold the other devices,
IP addresses in small home.
So that's why the currency is built into the router.
I mean, the starting to hit TV service, the settings will be the one and two one six zero zero two
to this one.
You can change if you are using that very large business organization to which is crustier.
That's why the routers default DHP service set to this crazy private IP address range settings and allows
you to seize this back address.
And she's you can sign minimum's like there is no place like this under the regular one.
So what the means?
It's our computer.
It's pointing to our computer.
It's localhost.
When you are doing some experiment, you open up a server on your computer and you use this address
to refer to this computer and this one.
Here they go, some wrong muskies.
Also the Congress course.
It is beautiful.
And you can also put the words on not one, that one, not one, which is also Eurocracy and one that
is on a tour of poverty, is also Uroboros.
I have tried this and it works, so you can have one hundred thirty one dollars that development work
to do it, so we can have all these IP addresses points to her own computer.
So let's see, what is this different network mosque.
So this network mosque has provided but before that network, when they are creating these networks.
And what this does is you will take an example and look at this one nine to do that one six two zero
zero zero.
This is our private IP address.
I have my home and I have set up a router which gives the IP address from here onwards, man.
And you do not want to share.
And if we convert this every offer from this multiple-entry, I get this one, this one here in the
binary one one six zero dot 168 in binary, one zero one zero one zero zero zero dark and zeros or zeros.
And so I have written this one this morning to try to reform it.
OK, now they have said that before the subnet, Moscow is 250 further to further to go.
Know if I can talk to to put it into binary.
I get this one.
Two terminals are ones and second octet is also to activate.
It also gives the Avants and same and zero means Arjuna's.
Not what I want to do is to get a number of those.
I need to convert this to binary to have already done and I need to do the an operation between my IP
address and this subnet mask.
So this is my IP address and this is my subnet, and I am going to place in operation and we have already
seen this operation and no transaction.
You can check the video if he has to.
So one, one and this one.
Right.
And one one.
That number gives one, if anything one because it gives digital.
So you can see here there are plenty for bitrate.
These are twenty four ones, eight once a consequence.
Twenty four ones.
So you can call this subnet mask as Rashbaum default to the shortcut for this subnet mask.
So the slash number twenty four twenty four.
This is the number of once you know subnet mask from left to right number of continuous ones.
So this is slash twenty four and you can see these are duros.
So the digital spots indicates that the host addresses.
So here from Rostock that you can change to get a Hofstadter's.
So if I change to Rashtriya to one I get one to 160 that direct one change to this one I get one nine
two two one six zero two.
So we change all these bits.
I can generate those many host addresses and I can assign those addresses to my computer or laptop or
any other smartphone.
So this is called Hostelry.
And this all this is called subnet by the network.
This indicates one network.
So 192 168 of GIRoA indicates one network.
And this one, two, three, four, one, two, not for the first to our host IP addresses so I can
assign one nine to 12 on that one to a computer.
One need 168 of three to my smartphone.
So this three octets ruminative because they belong to the same network.
And we can change this big one to generate another network, and I can change this to try to sell it
on the network.
And in that way, I can generate these many number of networks.
But in the whole it's unnecessary to create those mini networks, because even in one network, you
cannot have 256 devices in your home.
That's why generally we use 192 that one zero zero one two, three, four, five, six on it to send
the hostess's.
Even when you are in operation between a person subnet mask, you get the same three octets as the IP
address.
Right, because we are doing it and it's one and it's the same putting it.
And this last octet is differentiate.
It means really discuss the host IP addresses and the directions have been mascaras for hosts.
That means you can change these gyros and put some values.
We get the host IP addresses, we can assign those IP addresses to the devices on our home network.
The ones that have been most the network, but we have already seen this and we get plenty calls for
support for this crisis subnet mask.
In short, we can not disappear on the floor, so controversial, no, once in a.
So we have already seen that happen for once and we caught it.
And you can see for the last year, there are only eight ones.
Right.
Means eight once.
And you can define the subnet mask in the short form, slash eight.
And for the Krosby, there are 16 once because there are two of the two who have to face.
That's why you can define this as a short form.
And obviously you can.
Secrecy's subnet mask 24 24.
So this is the shot from every we can order to Veracruz to cover the shortfall.
And we can divide this network into smaller subnet, far safer for subnet.
So the manager asked you to create four subnets for this one and two to the 168 zero, one to the force
of nature.
How many holes?
We got 256 hosts.
So we can create 256 hosts, but we need four subnets.
So you what you want to do is you do a 256 with four number of number of subnets request 256 before
you get this.
Sixty four.
Right.
So you can see four to six to four hosts to one subnet and the second 64 host to another subnet.
And next for an exit to another subnet like that we can create four subnet.
Let's see the first subnet, 192 168 one, two, one, two, one, two.
Sixty four.
Right.
It's one nine two zero one 168.
One, two, one, two, two two one, one, two, three, four.
So these 64 IP addresses can form a one subnet and next to each four from 65 to 128, we can form an
address from 191, 192.
We can form another subnet and from one to prove to what we can do.
So in this way, we can form four subnets.
And in this subnet, if you look at the starting address, this is called Network for the subnet.
So 192 to 160, that one is connected.
So if you see the second subnet, you can see 64.
That is the starting one.
And it is Connect Kirkcaldy for the subnet and one dominant one and three are the network.
It is for the subnet.
And if you see this one last one is a sixty four and it is the broadcast for the subnet and 128 192
255 are the broadcast Ķiģelis for this subnet.
So this broadcast notice you use it for transmitting data to all the computers in the subnet.
Right.
That is the usefulness for this broadcast.
And with the network you can identify the network.
So we can have beautiful horse, but you can say to 56 horse flu ascender that.
So that's all you need to know about the subnet mask and you need to really focus on this crazier and
crazier, but at the strangest network mosque and these two, this gas is used in organizations and
you use it for home networks.
So this is somewhat very basic problems.
And you can also see some Advanta problems on sublimity, but this is the basic one.
So that's sort of what you need to know, something from the industry point of view.
