a basic scenario that ask the required number of networks
that is 80 and the minimum number of host that is 3000 and
the network address is 10.0.0.0 and i need to need how to
compute to get the answer on what is the subnet mask.

Answer Posted / rav

our requirement is 80 network and possible network can be 128 key value is 7 so we borrow 7 bits, which gives us 128
network and subnet mask is going to be 255.254.0.0
it also represents as 10.0.0.0/15
And host per subnet will be 131072.
