Some KZitem tutorial videos are much better than being in classroom listening to a professor who spends more than half of the time allotted to teach a subject, e.g., subnetting on digressing and jesting. By the time the professor gets back on track, some students lose focus and learn nothing. Good KZitem tutorial lessons are gradually replacing classroom learning. Thanks!

The last question in the video150.150.0.0/30 /30 simply means subnetmask in short, so it’s: 255.255.255.252 Here the IP address changes from class B to C, because the subnetmask tell us which portion is the network ID and which portion the host ID, in this case 255.255.255.252 It says the first 3 octets belong to the network and we cannot use it or change, the last octet is for the host and we can play with it: now 252 in binary is: 11111100 so: 2^6= 64 number of subnetworks 2^2-2= 4-2 = number of usable hosts. Am I right?
