hello i am new to this, i need to know how will i complete
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 / rupesh mehta

Here we need 80 networks. So, we need to have at-least 7
subnet bits which can gives us 128 networks. Thus, here we
can use subnet mask 255.254.0.0, it means /11.
Even we can use 255.255.240.0, it means /20. But, that will
gives us maximum 4096-2=4094 host.
