An IPv$4$ subnet is network inside the larger network, identified by a certain number of initial bits that are common to all the addresses in the subnet. The number of common bits $($aka the prefix length$)$ is given with a slash after the base address $($i$.$ e$.$ the lowest address$)$ of the subnet. The remaining bits are available to be freely assigned to hosts in the subriet. With the exception that the base address is reserved for the subnet number, and the last address Is reserved for the subnet broadcast address. These two addresses are still part of the subnet

For example, the routing prefix $192\mathrm{.}1681.\frac{0}{24}$ defines a subnet with a constant first $24$ bits? i$.$e$.$ with a prefix length of $24$ Available host addresses in this subnet are $192\mathrm{.}168x,$ to $\frac{192168}{254}$

$192168,1\mathrm{.}0$ is the subnet number, $192\mathrm{.}1681255$ is the broadcast address. Therel are $256$ addresses in this slubnet$/$and $254$ available host addresses.

How many avalable host addresses are there in the subnet $100\mathrm{.}0\mathrm{.}0/8?$ Enter the answer as a decimal number:
