in the most beloved class in this course, which
00:00:04
is
00:00:05
about college cars.
00:00:14
and we're going to talk
00:00:16
about vlsm that the net mask of
00:00:19
variable size wonderful more classes
00:00:21
that we get like this the jump is 64 this
00:00:23
knowing which presents almost users
00:00:24
now we're going to understand that it can only
00:00:26
vary Wow [ __ ] so it can be 12 nothing
00:00:29
no I understand if exactly I'll arrange it
00:00:32
straight away for the next course, then we'll
00:00:34
put more notebooks, what time are
00:00:35
you going to choose one closer today,
00:00:37
as long as they have one?
00:00:41
local network,
00:00:45
let's improve it, put the 9216
00:00:50
8.0.0 it, this mask will be
00:00:54
the /24/normal/inverted to normal Light it up
00:00:57
and Then imagine that you are working
00:00:59
in a company Yes, but you work in the
00:01:01
company, I am the boss, ask you that
00:01:03
you received this prize the life of 680
00:01:05
bagulho 0.0 to 24 mask be standards
00:01:08
people to see in previous classes je-shua
00:01:10
that he has a problem he wants
00:01:12
you to owe life this subnet in what
00:01:15
different situation so just put and
00:01:17
Quatro Estações for people this four,
00:01:18
right, take off your shoes before you
00:01:21
start organizing Here there's a
00:01:23
combined floor, no, it doesn't really match a
00:01:26
little arrow pretty caracu and well I'm going, it
00:01:29
can't be like that, look, this one understands, it's going to have to
00:01:31
be divided into four sub-networks But
00:01:35
each sub-network has The problem is that
00:01:37
we did it in the girl asked me
00:01:39
to tell me her name on Facebook she said
00:01:41
like this and how do I define this mask
00:01:44
and define the mask according to the
00:01:46
number of computers I
00:01:47
need on my network yes if I have
00:01:49
a network that I need 30
00:01:50
computers I am the machine for 30 60
00:01:52
or traumatic but now the situation
00:01:54
your boss gave you situation he
00:01:56
needs here in the IT Lab there is
00:01:59
12 and
00:02:00
in the lip What are the sectors laby laby
00:02:04
sex secretariat in Call Center Hall is
00:02:08
always missing just for a few like this
00:02:10
and they woke up beautifully How to define the
00:02:14
machine and the button HB20 20 computers
00:02:18
in the secretary 60 computers secretary
00:02:23
in the call center we will just need
00:02:26
to go at ease 120
00:02:29
call center computer is big and in coordination
00:02:31
we will only need sodium, please feel
00:02:36
and If you start sizing with
00:02:40
a fixed mask, you would have to separate it into
00:02:44
groups that would fit the largest the largest
00:02:47
gluing network, in other words, you wouldn't be able to
00:02:50
do it, I would have to think about
00:02:51
coordination with 120 computers and if
00:02:53
it was possible to do it and it
00:02:56
went up using the number of elements
00:02:59
first the hysteria if I were to use a
00:03:01
normal subnet network mask, right,
00:03:03
she wanted Jesus more classes I
00:03:05
couldn't do the scenario I can't
00:03:07
divide it into four subnets using this
00:03:09
IP address with the agent of 128 I
00:03:12
managed to do two I was going to miss it today And then
00:03:14
my variable size mask there
00:03:15
allows me to create several subnets with
00:03:18
different sizes using the same
00:03:20
IP class the same big network From here
00:03:24
to bottom to top in my organize and
00:03:27
then we need to do the following, you
00:03:30
know about a business like this, right? And this is
00:03:32
a network of variable size and the
00:03:34
first thing we have to do is
00:03:35
organize from largest to smallest, so
00:03:39
it was the largest network there that 120 then
00:03:42
come back here on top of the other and
00:03:46
120 after 60 then 20 then six
00:03:49
correct and now we will have to
00:03:51
create a subnet mask that drops
00:03:53
a lot and sells that it was 60 that was
00:03:55
selling helmet Is there any limit to this
00:03:57
stop if you thought to tell me well
00:04:00
so there is a limit there is the limit is
00:04:03
the sky is the limit what will happen in
00:04:07
a limit for this class mask
00:04:09
to be the limit it will be 244 computers
00:04:12
that only worried about not exceeding 254
00:04:15
here at this stop It's because everything is a
00:04:17
class mask and I must
00:04:19
only have one little bow 104 because this
00:04:21
is from the service class you
00:04:24
need more computer you can go
00:04:26
to other classes or you can use several
00:04:28
networks you couldn't have 9268 00926 8109
00:04:32
220 but like that 234 Guanabara is a button in
00:04:37
general, depending on how many subdivisions
00:04:39
they made, there will be four,
00:04:41
there will be less than the maximum, 254 it will
00:04:43
decrease as we do it, so
00:04:45
now we have to decide that I
00:04:46
think it will fit each one of these,
00:04:48
there is no there, let's go for the next one but for
00:04:51
our comic Let's go to our comic
00:04:52
and now put 120 for us we
00:04:55
're going to have to put on the mask of being
00:04:56
yourself there Oh ok, we have to do it let's go with
00:05:00
the money with 120 go score here and the
00:05:03
first ones go having to find a brand
00:05:05
that carries 120 computers,
00:05:07
the mask that fits 120 computers,
00:05:10
we're going to do a quick check, we
00:05:12
even saw there a mask that came out DF, right,
00:05:14
yamash, it was 120, the mask was 255 255
00:05:17
255 128 255 255 255
00:05:24
128mm, that's because what that we are going to
00:05:27
do to make your life easier and there is
00:05:29
a much more technical explanation
00:05:32
that we have there in the study, but so that
00:05:33
we can solve this
00:05:35
without you having a lot of headaches,
00:05:37
basically Guanabara, I convert this
00:05:40
entire Mask to binary account
00:05:42
How many zeros are there in 100 days and then I use the
00:05:44
form Lazinha 2 raised to the number of
00:05:46
zeros So cool, actually I don't
00:05:49
need to convert this because we 55 is everything,
00:05:51
right, we've already seen there audio 128 is what 8
00:05:55
bits, right, that's it and you go getting 1000 and
00:05:59
four more is one two three four five
00:06:01
six seven eight this here is 128 if you
00:06:05
don't know this one is one here oh 1 2 4 8
00:06:09
16 32 64 no 1 2 4 8 16 32 64 128 256
00:06:18
you put the [ __ ] in But then I'm going to
00:06:20
take more, this here is more, so calm down,
00:06:23
I'm going to remove this 0 button on the front,
00:06:26
it's not right for tomorrow, how many bits are there?
00:06:34
64 128 I'm going to put a fan in
00:06:38
front, we opened our
00:06:40
conversion store that we did in this course
00:06:41
here beauty beauty and now for me to know
00:06:43
how many computers each I have to
00:06:44
count the number of zeros they are 70 and then
00:06:48
I do two to the power 7 2 to the power of 7
00:06:51
which will give 128 - 2 because we have to
00:06:55
take two high numbers
00:06:56
is 128 - 2 16 126 does not mean that
00:07:03
in this network with this mask of 36 years
00:07:05
that we have the value we do this
00:07:06
calculation With this it gave 126 And then within
00:07:10
126 hangers on computers they go about the
00:07:12
six and then they say there are no six left
00:07:14
so put these six here in place, it's
00:07:16
not possible because it's another matter to go up, you have to
00:07:18
separate them into four nets to see Okay and
00:07:20
now let's do the next one Of course, but
00:07:22
don't waste it, you'll always be
00:07:24
desperate, it's a multiple of 2, it's a base, a
00:07:25
multiple of base two, exactly what do you
00:07:27
want to know which is the biggest number?
00:07:33
So
00:07:36
what's going to happen now we're going
00:07:37
to make the next one climb on you it was the
00:07:39
mask that we're going to use you had to
00:07:40
do it I'm going to do it because of it
00:07:42
Something of two
00:07:43
the
00:07:44
next one I'm going to have to do come on
00:07:46
let's go the next one climbs Oh, that's
00:07:48
great The next subnet is 60
00:07:50
sixty Let me see if I
00:07:53
learned I'm going to do one ok 60 computers
00:07:56
for 60 computers it's going to be
00:07:59
255 255
00:08:01
[Music]
00:08:03
255. Something that will give
00:08:06
something close to sixty the closest base two
00:08:10
is 64 it has to be 2 to the power of
00:08:18
12 48 of elevators
00:08:22
3264 here it is 0 1 2 3 4 5 6 two the sixth
00:08:28
which is 64 correct right so what I'm going to
00:08:31
do is 64 you have to take two a little bit
00:08:34
even though I forget no then but then it doesn't
00:08:36
work that way we have to
00:08:38
remember that class of hurting the way
00:08:40
we saw it for your address too much
00:08:43
and until you're six years old I can't
00:08:46
have alternation between 10 yours one so
00:08:48
then it has to be like this ok. to be 6
00:08:50
Eros a on the post alternation can't And
00:08:53
then how do you do it I don't know is the quantity
00:08:55
of 0 the cheap so I have to do
00:08:57
a pick up there I would have to do a two three
00:09:00
four five six zeros da So just
00:09:04
put it exactly there damn So just
00:09:07
do 128 plus 64 Chape no Let's
00:09:13
take two, right here you'll need
00:09:15
to take two and did to the power of 6 do minus
00:09:17
two always do - 2K podcast network address
00:09:19
remember we take it there
00:09:21
it will give 62 in ugly that fits
00:09:24
perfectly in 60, there's no more pain, so
00:09:26
great, so if he just does 128 plus
00:09:30
64 and it will be
00:09:33
1275 92192, then it would be 255 255 255 192 I
00:09:40
understand that, Guanabara did a
00:09:43
reverse engineering Seriously, I thought
00:09:45
reverse engineering is also possible, I haven't
00:09:47
already said it, I'll go come back here now 20
00:09:49
let's go 20 computers I'm going to do one
00:09:52
come by and ask me if you
00:09:53
see if you feel like you deserve it Alfredo deserves it I don't
00:09:56
know if it's the same night again
00:09:58
Now I have to do 20 20
00:10:01
computers So it will be 255 I'm using it
00:10:05
here which is more classy face
00:10:07
being a point something I don't
00:10:10
know what it is in 20 the closest is
00:10:14
32 how old do I have to be to the
00:10:18
power of 2 to the number of
00:10:20
zeros of 20 Hello really close
00:10:22
heart who will it be 1 2 4 8 16
00:10:26
ready 32 to 32 exactly So it's going to
00:10:29
be two to the fifth and it's 32 - 2 is going to
00:10:34
be 30 thirty it's within 20 It fits
00:10:38
fine
00:10:40
it was there and it does well nothing has to do
00:10:43
anything it 's not one two three four five six seven
00:10:48
eight because there it counts the night because there are
00:10:50
always eight days without a bath,
00:10:53
I would be 128 plus 64 + 32 which will
00:10:58
be 192, right, we have already seen before plus
00:11:01
32 of four 224 224 to make a hammock
00:11:07
that supports 20 with 30 computers,
00:11:10
actually well 20 then we look and now
00:11:14
I'm out of space and now I'm going to
00:11:16
tell you what you can do, that's what
00:11:17
we did, there's this mask
00:11:20
that 128 tells me that 126
00:11:23
computers can fit. Mask here 192
00:11:26
tells me that it fits 62 computers and this
00:11:29
mask that I dedicated to myself and 30 what I'm
00:11:31
doing is using the number of networks
00:11:33
to fit the number above there will always be
00:11:36
a different one it will be a waste,
00:11:37
exactly you can force it instead of 120
00:11:39
you need to have 26 computers, yes,
00:11:41
then there's luck and misfortune for the cat, but
00:11:45
otherwise you'll have to have it, I'll never
00:11:48
waste it if you used fixed ones and
00:11:50
the difference is much more because then you
00:11:52
can, for example, if I used
00:11:54
fixed size it would be 120 computers and the put
00:11:56
126 of 126 220 but here below for
00:12:00
example if I put 126 I was going to use 20 and
00:12:03
I had 106 left and it meant I couldn't
00:12:05
put any other network remember me we
00:12:07
don't understand this big collection
00:12:09
organizing this whole parade here I
00:12:10
think I I'm going to do my hair right
00:12:12
here, your editor will love me, your
00:12:14
editor, who is now Nossa Editora,
00:12:16
won't last long either, why don't you
00:12:19
think, people have to squeeze in
00:12:21
if they find a way there, now here's the thing,
00:12:24
I have six computers, lastly
00:12:26
I have a doubt that this will remain
00:12:29
Hold on
00:12:30
255 255
00:12:33
255. Something that will be for me
00:12:36
to arrive at 6:00 the base of two is eight
00:12:40
close so I'm going to do two here it
00:12:43
has to be Hi, 8 is two cubed that's
00:12:46
it here, but it's 8 - 2 which will give you
00:12:49
a feeling And if it were seven here it wouldn't
00:12:54
give anything then I would have to go
00:12:57
from 18 to 16 instead of 18, that's also where I
00:12:59
waste a lot Yes but that's what you can
00:13:00
do no It's the same, you get closer
00:13:02
than that here, so six,
00:13:04
so I'm going to put three zeros because
00:13:06
here it's two cubed, right?
00:13:14
If you use the quantity to count the value
00:13:15
is not the quantity of computer I think
00:13:17
the e 128 plus 64 232 plus 16 plus
00:13:23
eight which gives how much 248 exactly I already
00:13:25
did it here leaves 42 okay I understand so
00:13:28
I have four 4matic masks I have
00:13:32
everything 25525 simple at the end 128
00:13:35
final 92 final 224 final 248 this ending
00:13:39
2 128 will give me the possibility of 120 Hi there
00:13:43
are two with the republic 106 rustic
00:13:47
regret 192 will give me the possibility
00:13:50
of 62 Holtz I need your 6022 final
00:13:54
224 will give me the possibility of 30
00:13:57
Holtz I only need 22 48 will you give me
00:14:01
exactly your faces I need
00:14:03
this I can't fall on my own here there are
00:14:06
a lot of people who are getting a lot of
00:14:07
things a lot of questions and what I ask
00:14:09
now and now we already know the
00:14:11
need now Let's go there to
00:14:12
clarify to fill up until now
00:14:13
you understand why Guanabara is
00:14:15
putting 10 randomly going
00:14:17
backwards because there at the magic time
00:14:19
we said everything at the beginning and this all
00:14:22
generates ended venting number one 21 the
00:14:26
next one and zero all the others
00:14:28
They are necessarily serious 21 always on the
00:14:30
left bt0 always on the right this
00:14:32
number of zeros is to express the
00:14:34
number of computers that fall into the network
00:14:36
the more of them I have the more
00:14:38
computer João I ended up remembering that
00:14:39
everything is a multiple of 2 the fewer
00:14:41
yours have the less computer each one there
00:14:43
beau and no peaces two takes a course of 24
00:14:46
is two exactly so in base two it has
00:14:49
to be base two it has to
00:14:51
be one of the bases of the two raised to 0
00:14:53
of Saturday in a month perfect perfect
00:14:55
perfect Beleza has to I'll do it now,
00:14:57
now we've determined all the
00:14:59
masks Ahan, I'm going to write all the
00:15:01
masks here, I came back here with a table
00:15:03
that I created on my own, it was very quick
00:15:05
to do it, you saw it in the edition, we're there,
00:15:07
the laboratory network would have this, the
00:15:10
mask we generated. for the
00:15:12
laboratory it was this one from the secretariat it was
00:15:14
this one from the call center it was this one from
00:15:16
Coordination that's why And then the big thing
00:15:19
about vsm is that all these subnets where
00:15:22
the same network was using
00:15:25
192168101 is annoying but like and now you
00:15:28
put them all up there they're going to be
00:15:29

00:15:33
168
00:15:34

00:15:45
'm going to have to wait, my God Don't

worry, you weren't waiting,
00:15:49

00:15:51
learned how to determine the amount of
00:15:52
computer and according to the mask.
00:15:54
Guanabara did his calculation, I
00:15:56
think we learned. What is it
00:15:57
possible for me to create subnets with
00:16:00
different sizes within the same network? I think
00:16:03
someone is going to sleep a little
00:16:05

00:16:06
a little more, okay? waiting for the next

doping in sports, so if you He's a
00:16:24

00:16:30
busy now, right? Then the caffeine
00:16:34
