Question: Subnetting is considered a way to more efficiently size a network without wasting IP addresses. After seeing the impact a subnet mask has on the number of available hosts, what could be considered some limitations to adjusting a subnet mask when sizing networks? (It may be helpful to consider the case when the number of hosts required is only slightly larger than a particular subnet mask value can provide - For example, what if you needed to provide addresses to 130 clients and your subnet mask only provides 126? ).
