Welcome to networking practicals in this practical, we are going to see how to find out the physical
address of a machine that is the Mac address.
Mac address is a 12 digit hexadecimal number that is a six byte binary number, which is mostly represented
by Kolon hexadecimal notation.
So go to the search window and type command prompt.
And press enter.
You can see it is C colon slash user slash admin nowadays, admin admin is the name of my computer,
the person who is using this PC and the person who's logged in into this account right now, this name
may change your environment.
So the command to find out the Mac address is similar to command finding IP address with a slight difference.
So type IP configuration before pressing enter.
If you're using a Linux based machine, Ubuntu based machine, then the command to find out the IP address
is I think it's not IP config.
So now press enter.
A lot of stuff appears on the screen and do not worry, we will tell you how to calculate the Mac address.
So in the first column, you can see the hostname.
It is the name of my PC.
It's not Admon because it is a name by the manufacturer coming down to Ethernet adapter Ethernet.
You can see it is disconnected.
Now, what does that mean?
That means that right now nothing is connected externally to my computer, not a printer on either USB,
nothing.
So if anything, it's connected to a computer and external media.
My Mac address will be three four six four eight nine six zero eight nine that you can see.
The Mac address is for wireless LAN adapter local area connection star three is different than the Mac
address for Internet adapter.
This happens because Windows creates virtual connections which are reserved for specific purposes and
only in such cases.
The Mac addresses can change because each connection has its own Mac address coming down.
Two wireless LAN adaptive Wi-Fi.
It's a big information table there you can find the physical address.
That is easy for easy for for nine, easy e three.
That is the Mac address of my PC currently in which I'm loving, you can see the dynamic host configuration
protocol is also enabled for my PC, which clearly means that the XO can assign IP addresses dynamically.
And yes, auto configuration is also enabled.
In the last lecture, in the previous practical, we have used IP Conflict Command to find out the IP
address and you can see the IP address is seen.
Then we find out the IP address and you can cross-check that.
The address is seen in this lecture as well as in the last lecture.
And since my IP address belongs to Class C, the default subnet mask is two fifty five point two, fifty
five point two fifty five point, all the information also states its some information about the server
and the client.
You can see that the servers address is one ninety two point one sixty eight point forty three point
to zero.
So you can see another one last column, Ethernet adapter, Bluetooth network connection.
Right now, my device isn't connected to any other Bluetooth device, and hence it is showing disconnected.
So if my device is connected to another physical device, then my physical address will be e c, e,
c four four nine.
You know, all these are hexadecimal digits.
So we have seen commands, IP config to find out the IP address and IP config, all to find out the
entire information in which your Mac address is also shown.
