      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 CZcams 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 CZcams 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?
