Subnet the $172\mathrm{.}16\mathrm{.}0\mathrm{.}0/16$ address space using VLSM based on the number of host addresses needed in the topology as follows:

$1.$ SW$1$ LAN requires $30$ hosts.

$2.$ SW$2$ LAN requires $30$ hosts.

$3.$ SW$3$ LAN requires $30$ hosts.

$4.$ SW$4$ LAN requires $30$ hosts.

$5.$ SW$5$ LAN requires $14$ hosts.

$6.$ SW$6$ LAN requires $14$ hosts.
