You are an administrator, you want to build a network with $30$ subnets, each with $6$ hosts if we were using the Sub$-$ID

$192\mathrm{.}168\mathrm{.}20\mathrm{.}0.$

Note $1-$ You must use the last available$/$valid IP address in the subnet range for fast$-$ethernet $1.$

Note $2-$ The first and last subnets are invalid for this scenario.

Answer the following questions related to these requirements.

$\backslash$table$[[$Sub$1$ Sub$2,$Sub$3,$Sub$4,$dots..........,Sub$29,$Sub$30,$Sub$31,$Sub$32]]$

What is the broadcast address for the first valid subnet?

A host address $192\mathrm{.}168\mathrm{.}20\mathrm{.}220,$ which network$/$sub$-$network may belongs to$?$

What is the the broadcast address for the valid$-$subnet $28?$

What is the the broadcast address for the last valid subnet?

What is the the Sub$-$ID for the valid$-$subnet $29?$
