Let us look at what is an IP address and what there’s a MAC address to explain. This let me introduce two characters Alice and Bob here the names Alice and Bob are like the IP address of the computer.
As a fact that alice is a woman and Bob is a man are like the MAC address of the computer it is unique and can never be changed nor can it be same alice name can be changed to Jesse Lisa etc and Bob’s name can be changed to Henry Harry Potter etc just like the IP address of computer.
The IP address is a 32-bit address that is split into four box eight bits dot eight bits the eight bits or 8 bits and it is a binary language by nearly language is composed of number 0 and 1.
Let us take an example of an IP address with all the bits are once this binary format has converted to decimal language to make it convenient for us to read and manage the decimal equivalent of eight one is 255.
The IP address is split into five classes plus a B C D and E these are the range of each individual classes and notice that the only first conflict of the first eight fifth or the first value alone changes and rest look similar.
We will look at how we arrived at this value in later videos in order to use the IP address we need to know blocks of this map the subnet mask for Class A B C D and E are this with the subnet mask for Class B and en are unknown as a dis useful research and with a G purpose so what is a subnet mask there is a very important field that says which class an IP address belongs to and gives more meaning to an IP address.
Let’s take the scenario whether the three computers connected we’re out routers as a device we use in a daily life but gain access to the Internet now let us say that the IP address to first computers the standard 0.01 is the subnet mask of 255 dot 0 dot 0 and I see answers in the second computer this 11.00 that one it is a death mask of 255 dot 0 dot 0 0 and the third one is 1200 at 1 the subnet mask of lips / 0 0 0.
Now looking at the IP address and subnet mask we can conclude that this is a class a network and also the sublet masters ask what part of the IP address and network bits and host needs to understand this better.
Let me explain the scenario: Once there are two families, the Anam family and the Jakob family, Adam has a wife and two sons, my sons Adam and John.
Adam Jacob has a wife and two daughters, the daughters named Arkady Jacob and cabbages. Now note that the children carry the family names.
You can address each individual by using the first name, or you can address in that family using the family name. So, the family name is called the network bit, and the children’s first name is called the hostess in an IP address.
No matter how many children you have the last names will be the same to denote that they belong to a particular family similarly in an IP address do not what bits of considered as Network bits or another words to denote which computer belongs to the same group.
We use a death mask so the roof of computers are said to be in the same network when their network flips are the same and host bits will vary depending on the number of computers connected in a network.
We will be simulating a real-time scenario in Cisco Packet Tracer’s next video so that you can understand what is a network now the MAC address marcanvis is given by default by the manufacturer of the Hall computer.
It is a 48-bit address which is represented in hexadecimal. The MAC address looks something like this: the first three fields purpose in the manufacturer, and the rest we feel represent the host computer.
Now let us try to find behind the address and MAC address of your computer, once you are connected to the Internet would it be search and type in CMD. It’s a schema from opening the command prompt and typing in the command IP conflict, so here you can see the IPv4 address. IPv4 is abbreviated as IP version 4, so there are two versions: IP version 4 and IP version 6. So, we will be looking I be version 6 in later videos.
For now my IP address is 192 168 1 dot 100 and subnet mask is 255 255 255 0 so concerning the IP address in the MAC address I can see that my computer is a Class C Network so to find in MAC address type in the IP config space forward slash Hall and press Enter.
Here, you would find something called a physical address, so the physical address is your MAC address. Since I have the Wi-Fi enabled, this is the Wi-Fi adapter, so the physical address study can be 3d 90 to play.
This is the MAC address of my computer, so this is how you will find the IP address and MAC address of your computer.
