An organization has the IPv$4$ address block $172\mathrm{.}67\mathrm{.}136\mathrm{.}0/19.$ This organization wants to divide its subnet into

three subnets by relative locations. The possible maximum number of hosts with respect to the locations are

shown in the following table. Plan an IP distribution for each subnet by dividing the current IP block into

subnets. Assume a router will be installed to manage these subnets. Write the IP scopes and their Masks with

respect to the locations.
