Question

What is the greatest number of bits you could borrow from the host portion of a class B subnet mask and still have at least 130 hosts per subnet

Answer 1

The greatest number of bits that could be borrowed from the host portion of a class B subnet mask and still have at least 130 hosts per subnet is 10 bits.

What is subnet mask?

A subnet mask can be defined as a logical subdivision of an internet protocol (IP) network into a 32-bit number by setting all host bits to 0s and all network bits to 1s.

Ideally, a class B subnet mask is made up of 16 hosts bits per internet protocol (IP) network. Thus, you should determine the number of possible host in a class B subnet mask by using this formula:

Y = 2ⁿ - 2

Y = 2¹⁶ - 2

In conclusion, the greatest number of bits that could be borrowed from the host portion of a class B subnet mask with at least 130 hosts per subnet left is 10 bits.
