We have a given IPv$4$ address that belongs to a network interface: $221\mathrm{.}165\mathrm{.}83\mathrm{.}44$ along with its mask $255\mathrm{.}255\mathrm{.}128\mathrm{.}0/17.$

Split the network to which the above address belongs into $15$ subnets.

The destination data of these subnets, for each subnet, including their given name and the minimum number of network interfaces of each subnet, are as follows: $($L$,6570),($U$,668),($I$,726),($P$,121),($M$,1165),($H$,9),($F$,244),($Y$,3),($E$,1399),($C$,2),($J$,2895),($X$,1),($O$,5247),($G$,11),($Z$,1746).$

For each of these target subnets, specify:

$1.$ the address of this subnet along with its mask,

$2.$ the broadcast address of this subnet,

$3.$ the size of this subnet, defined as the sum of the following parameters of this network: the number of different network interfaces, the network address, and the broadcast address.

In order to achieve unambiguity of the performed splitting, you must follow these rules:

$1.$ The allocation of addresses to individual subnetworks is done from the largest to the smallest network $($according to the number of given network interfaces of a given subnetwork$).$

$2.$ In case of equal number of network interfaces, lexicographical order $($A$->$Z$)$ of subnet names is decisive for the splitting order.
