So now probably one of the bigger difficulties that people are usually referencing is what are subnets
so networks can be broken down further into what are known as subnets.
And, you know, as the name implies there, they're just some networks that grouped together specific
devices that can communicate with each other.
You may have seen like an IP address, right?
Like like this right here with like a twenty four after it.
So actually represents an address range for a 24 subnet.
So now let's break this down a little bit, because I'm sure you're probably confused.
So here's a breakdown of subnet and you probably copied this chart down, take a screenshot or write
it down somewhere just so you have it as a reference.
Nobody, almost nobody remembers this typically unless you've been working on this for like 10 years.
So let's go over, like, how the IP addresses form and we'll understand something suddenly a little
more.
So an IP address is made up of four numbers that range from zero to 255.
And these are separated by the dots.
You've seen that and the other examples, or you see it right there, too.
There's dots in between each of the four numbers.
So these numbers are called octets because ultimately made up of eight bits.
And Bitzer, just one zero sum over that.
So all together and address contains you this because we have four octets, which A.K. four numbers,
each one of them Ebbetts eight times forward, that's thirty bits.
Now, when we talk about a 24 network, it simply means that the first twenty four bits or the first
three sets for the first three numbers are set in stone.
Those numbers are not going to change.
This is known as the network address.
So we have a subnet like one nine two one six eight one nine zero twenty four.
The one nine two one six eight one part is going to be the same for every single address on this subnet,
with the only difference being the last octet or the last number, which is the zero that you see right
there before this 24.
So as a result, you know, twenty four subnet, you only had two hundred fifty six addresses, a.k.a.
you can only have 256 Hossaini.
So you can look at the little chart over there on the right and it's going to tell you, you know,
the, the mask, which is what represents, you know, the twenty four.
Twenty five, twenty six.
That's the network mask that represents that.
And it tells you how many subnets there that that specific type of subnet can have and then how many
hosts you can have as well.
We Arakawa's like I say, you know, just keep the chart handy just so that, you know, you can always
represent understand like twenty eight.
Oh what does that mean.
And you have this chart, you understand exactly what that means.
A good.
