All right welcome back exciting I think terminology.
Aren't you excited.
I'm excited.
All right.
MBA abettors one digit either a one or zero.
That's cares where right machine go.
And once computers do not know anything else but you're are ones binary.
OK so this is a minor a bit on the one on the A by 7 or 8 bits 8 bits 8 bits.
That's all going to be working with a bits.
Makes about 8 bits creates the number 8 bits create the letter I see.
So 8 bits 8 bits a bits an octet
an IP version 4 There are four octets us each Octa is eight bits long eight times for 32 which is a
32 bit IP address.
So they get answers each other.
It is a bit that means it creates a character and that's always the number.
OK.
That's what and often thoughts at each other about this.
Now no I've addressed what's org.
Our address lets you know hey I belong in this network.
This is my neighborhood right.
That's what an Arab address is tells you.
OK.
You belong to the turndowns rules rules will not work are the ones I want to see things that are an
hour or two.
Why did you want to see one does you an hour whatever.
That's the word you live in.
OK.
Your segment's the broadcast address if and when it is used it is used to send information to everyone.
Ok broadcast is not something we want to do.
We try to avoid broadcast as network engineers.
Why.
Because broadcast is bad.
But the addresses used by applications and host to send information to all nodes our network is called
abroad and the job they say broadcast is backed OK.
Minimize the amount of broadcast what you want to increase the Armato broadcast domain.
More broadcasting means less broadcast will be admitted within that particular.
Where are your devices coming devices coming.
So here are an IP address for.
It's a logical.
What is the question.
So I ask a question about what does it lead you to it's a logical address that's given to know what
the node any device directly connected to remember that's or not is OK.
If you're part of a network you are a node.
If I plug myself in I have a point.
All right.
If I connect myself to the network I think I am part of that network.
Therefore I am given an address given.
Now we're going to pass and a host address.
What is that.
OK.
All the IP addresses separated into two parts.
One part is the network address the host address.
Who does that.
Some LIT-MATS kind of a little bit but that's OK.
You can see the some of the mask is the key to all the answers that you can ever hope for an IP address.
OK.
Because it won't let you know.
What part is your network and what part is your host ID in this case.
This particular or 2 5 5 5 5 5 5 0 0 0 means that these first three octets are taken up.
Therefore that is the network and then the last part is the host which is zero means you can do anything
from 1 to 2 before.
OK.
That's what the pseudonymous does.
It is key.
That's the key right there on some math your computer is much and your router knows we will let you
know.
The gateway address.
Another logical address.
I know this is the last standard I'll buy food.
OK.
I like to use the last available IP address for my Gateway addresses.
This is just me.
All right Microsoft.
First of all what if you will say why.
That's all I wanted to say one of the four and I say we're using this mask right here to fight with
you.
This will actually be my PC right.
And this will be it's gain weight and that will be the last.
So you need to know that is your game where you need to know what your gateway is your gangways doorway
to the outside which is the router or for those of you that like to use LAYER three switches as your
layer 3 switch.
OK.
But you need to know this you need to know this and the DNS address.
Well it's there is nothing is optional but if you are going to use DNS in your network it will be nice
if you put the DNS address on the server in your PC.
OK.
And if there are so the router to use DNS to resolve all they will as well.
OK.
So it's extremely important that you know this is just terminology but it's something that you asked
me what an IP address was your day.
OK.
If somebody asked you who was going to look for something that was something that you ever do that in
front of anyone.
OK.
You better know what this is OK and you don't know where they go.
OK.
And we go to the properties of UTC Bapi protocol.
It will be right there.
You can either get it through the VCR or you can put it in statical yourself.
They know what an IP addresses.
No the the key to everything is there something in math.
No the address is going to be the door to go outside your network which is your router usually your
layer 3 device or I say that way for you the switch gurus and then you're the gateway and and the address.
Don't forget it.
OK troubleshooting troubleshooting.
I can't get to the ernet.
You have to get where you have the right mask.
Do you have the right IP.
OK.
I can't resolve.
Will it does it gives me some sort of weird error.
Do you have a DNS address.
Are you getting a DNS address in order to resolve that because the NSA asked what it does.
One of and he's looking for Google.
Hey do you have an entry for Google.
We're not here to ask you don't want to go to or not.
So non-service they know the entry for you and so forth and they'll look they'll keep looking for DNS
servers until they find oh google is this IP.
OK here we go.
So you need to know we need to know each other DNS address.
So it's just basic IP terminology something you can.
