Charles is designing a subnet for a small office.

He reserves the subnet $127\mathrm{.}100\mathrm{.}100\mathrm{.}0/24$ for the servers in the datacenter. The equivalent notation for that is $127\mathrm{.}100\mathrm{.}100\mathrm{.}0$ mask:$255\mathrm{.}255\mathrm{.}255\mathrm{.}0,$ or the IP addresses $127\mathrm{.}100\mathrm{.}100\mathrm{.}0-255$ will be reserved for the datacenter.

This will not work. What is the problem with the reserved IP address range?
