      If 1111111.111111. is the subnet mask , then what is 255.255.255.240 is that just a subnet and not a subnet mask/ would there be a difference between a subnet mask and a subnet?

    Some TH-cam 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 TH-cam tutorial lessons are gradually replacing classroom learning. Thanks!

      when determining which class a network is how do you identify that the first 2, 3 or 4 octets are the ones that will stay the same? For example , if 150 is Class ''B'' range so first 2 octets of network portion wont be changed. Does this simply mean that class ''B'' is always the first 2 octets. Its not about how high or low the first network number is right?

    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?

    So, subnets and hosts numbers go together in this that, the number of hosts is going to be allocated to the subnets. 10 subnets and 20 hosts means, it's going to be 20 hosts per subnet.
    Resulting in a a network of 10 subnets and 10 x 20 hosts.
