I use 192.168.2.1 as a gateway for Internet. The last digit (1) is the routers host adress in the 192.168.2.0 network. Now if nthat routers gonna help my computer to connect to the internet, it has to know my host adress aswell, beside from being in the same network of course. Same thing goes for my computer, it has to know that I want to connect to my router and its host adress.
192.168.1.2
255.255.255.0 the computer knows that it has to search within the last octet to find my router.
you told that no. of 255 in subnet mask told about the class of ip.
But if you can identify the class just by observing the first octet in the ip, then what's the point of defining subnet mask ......help me i am little bit confused
i think i might of missed it but could you tell me how mathematically you get 16,777,214 max host per network on an A class & 65,534 for a class B? What was the formula to determine the number?
I watch this video and I finally understand some things! However some questions are remaining not for your examples.
For example we have the IP address 192.134.7/28 with CIDR
We have to find the Network address and the broadcast. Because it's difficult to me to calculate this I use an online program that helps to find out the answer.
The program tells the network address is 192.134.145.0 so far so good!
But the broadcast tells that is 192.134.145.15 and the question is where comes the .15???
he have the private addresses wronge because if the 172.16.0.0 is the starting private nº the ending should look like the same 172.31.x.x and in the picture at 4:51 it is 17. which is wronge it has to be 172.
This part helped me to know the Private Reserved Addresses.. but i already knew that.. i have a exam tomorrow of all this shit and i gotta memorize all these 5-6 videos in my mind.. and that's not a big deal cause it's quite easy for me.. but what is dificult for me is cisco it sucks... i have to read all that we did again.

@intelligent0123
255 doesnt tell about the class of the IP, First octet in the IP adress is what tells you that.
255 is used to differe whats network and whats host numbers in the Ip adress.

do you mean the range in 172.16.0.0. To 17.31.255.255
should be 172.31.255.255
why there is 17

Top class explaining. The best I've come across so far.
I was so confused with other explainations both online and offline.
It's not about what you know as there are tons of people who know about this topic but still cannot explain to a beginner.
This guy has explained it very well so far.
Keep it up Matt.
