Three of these subnets only need two host addresses, because they connect only two routers. Let's take the first subnet here and divide it again into three additional, smaller subnets. Answer the following questions:

$15.$ If you borrow one more bit from the host portion of the IP address in Subnet $1,$ how many smaller subnets will this create? Is this enough? $16.$ If you borrow two more bits from the host portion of the IP address in Subnet $1,$ how many smaller subnets will this create? Is this enough? $17.$ What's the new subnet mask for these smaller subnets? $18.$ How many hosts can each of these smaller subnets have? $19.$ Fill in Table $8-13$ with the smaller subnets' information. The first one is filled in for you.
