I'm reading "Windows Networking Essential" and my question is about subnetting.
I understand that in order to create subnets, I need to borrow from the host bit of the address.
In the book, it says that
...you can use the following formula to determine how many subnets you can create based on how many bits you borrow: 2n, where n is the number of bits you borrow.
So if I I want to create four subnets, I borrow two bits, if I borrow three, I get eight subnets etc.
But how do I create, for example, six subnets?
For example, with the IP address 192.168.50.0 how is it possible to create six subnets?
To create four subnets, I borrow two bits:
11000000 10101000 00110010 00
What would you do to create six subnets?
Another important question is: If no network mask is given, can I assume that it's 255.255.255.0 ?
