OK, in the last lecture, we have an introduction to the DCP server, and as I said, I'm going to
talk about the DCP server operations in this lecture.
So now let us see.
This PC is your PC.
Let me use the pen.
Yes, this is your PC and this is the DHP.
So, OK, so now what happens now?
The first step is the DSP client broadcast the DSP Discover message, which means that the client or
the host in this case, which is your machine, will ask the DSP for an IP address.
Now, I want to tell you one thing that you you will have a question in your mind that why would my
PC need an IP address?
I already have an IP address.
Well, when you log into the Internet, your IP address keeps on changing, right?
You do not have the one static IP address when you are connected to the Internet.
Your PC has a separate IP address and a separate MAC address, which is Hardcoded Mac address.
And the market doesn't change, but your IP can change.
So when you connect to a VPN at that time, what your host does is your host as the Via VPN Liedtke
server to give you an IP address.
Now the next step is the DSP server request replies with the DCP offer a message saying that, hey,
this is the IP address or the pool of IP address, which I'm giving you.
So if you're okay with it, just let me know.
This is the IP address.
Now your host will see the ACP client responds with DXP request message.
It says, OK, I would like to have this IP address, so please give me this IP address.
And finally, the DHP sort, complete with DHP acknowledgement message, and after this step is done,
your PC will finally get the IP address and in this way, DHP server actually works.
Now, if you need to provide an address from a DCP server to hosts that are under the same local area
network, you can configure your router to relay or forwarder.
DHC declined requests.
Don't worry.
Let me explain you in simple words.
For example, let's say you have two networks, OK?
You have two networks.
Consider this as the E network and consider this as a network and consider this as the IT talk so that
it works and your host is here and your DCB client is here.
This episode is here and now you need to provide addresses.
But but this DXP server has already been full of the addresses.
It doesn't have any more addresses.
So what you do is you take you want aggressor's from this DCPI circuit, but this isn't another network
and you are here.
So what would you do now?
You first will contact this DCB server for full of addresses, but this DHP Soroses that, hey, I don't
have any more addresses as the addresses are full.
So what is DCP really is actually this server transfers, the requests are basically forward, the request
to this server here and therefore in this way this DCB server can respond back to this server and then
this server can respond back to you to get your IP address.
This entire process is called as DH Sepi really or DCP Forward.
OK, congratulations.
I'm really proud that you have made this lecture and it takes real enthusiasm and real motivation to
do now.
Now we have completed the major networking devices that will be required in your coursework or during
your interview preparations.
In the next lecture, we will have an introduction to other network devices, which also exists.
And I'm pretty sure that no other course on the Internet or on any other platform will teach you these
other devices.
So it's my humble request that if you are really enjoying this course, I would just expect a reading
from your site.
It almost takes only 30 seconds to give a rating.
That's all instructors can expect from you.
And if you motivate us, your feedback really motivate us to do more courses.
So in the next lecture, we are going to start or have an introduction to the other network devices
that are really very important from networking point of view.
