    This man is an invaluable resource to the networking community and should be honored and protected by the internet almost as much as Brendan Fraser.

    A quick way to get the block size is subtract the subnet size from the next available octet and then use ^2:
    E.g. /28 ...
    32-28=4 ...
    2^4= Blocksize 16

      Another way if you don’t have the CIDR value is to take 256 and subtract the value in each octet. 256 - 255 = 1 Or in your case with the /28 256 - 240 = 16

    I came to this video almost 2 years later and still found it useful, but I find that If I already know the DDN for a CIDR notated subnet, I minus 255 from that value - so for /28 I would do 255-240 = 15
    IDK Just figured I'd share in case anyone like me still finds this video.
