Hello, everyone.
In today's edition of sequel series, I'll discuss about IPv4 address network and host Bush and also
we'll discuss about subnet mask.
Each network running TCP IP must have a unique network, no, and every machine on it must have a unique
IP address.
The bytes of IP addresses are further classified into two parts.
The network but.
And the whole spot.
The network board specifies a unique number assigned to your network.
It also identifies the class of the network assigned.
Part is a part of the IP address that you assigned to each host is uniquely identifies this machine
on your network.
Note that for each host on your network, the network part of the address will be seen, but the host
part must be different.
But how do host know which portion of 32 bit is network and which is host?
That is the job of the subnet mask in describe the parts of the IP address that are used as the network
and host addresses are not fixed.
So the network in the host addresses about cannot be determined unless you have more information.
This information is supplied in another 32 bit number called a subnet mask.
When an IP host is configured.
A subnet mask is assigned along with an IP address.
Similar to IPv4 address, the subnet mask is represented in Dot Dot Dot decimal format for ease of use.
Like the IP address, subnet mask is a 32 bit long.
The subnet mask signifies which part of the IP address is network and which part is host.
The subnet Macias compared to the IP address from left to right.
Bit by bit, the ones in the subnet mask group isn't the network portion and the zeros represent.
The post-abortion.
No, that the subnet mask does not actually contain the network or host position as an IP address,
it just tells the computers where to look for these positions in a given IP before address.
Let's take an example, Judy, to remind the network address and the host address of Blue Ivy 192 168
123 Dot 132.
In this example, the subnet mask is last 24 or you can call it as 255.255.255.0.
So the subnet mask, if you can work in binary, will be twenty four zeros.
So dreadful ones and zeroes.
Lining up the IP address and subnet mask together, the network in the host portion of the address can
be separated.
The first 24 bits that I'm one of the ones that have been mascot identified as the network address with
the last it was the number of remaining zeros in this mosque identified as the host address.
This gives you the following network address in binary format.
And then network addressing decimal format will be 192, 116, 123 or zero.
And the host errors in binary format will be.
Which if you convert to decimal, we will have an who stayed with us.
One, three two.
So now you know, for this from this example, last seven mosque and the network, it is 192 168 one
to edit or zero and the host addresses one three two.
That's it for the session.
In my next session, I'll discuss about IP address classes.
