How do I take that $1$ address and subnet it for these $17$ subnets?

$-$ Question? How many bits do I steal for $17$ subnets?

$-$ Subnet mask will go from $255\mathrm{.}255\mathrm{.}0\mathrm{.}0?$

$2.$ Based on how many bits you stole from step one, define the subnet numbers for subnets A $$ Q

$-$ Turn on the bits to get the subnet number starting on the rightest bit.

$-$ One of the subnets will be identified as $150\mathrm{.}10\mathrm{.}8\mathrm{.}0.....$work out the rest!

$3.$ Understand the range of valid addresses after we number all these networks.

$-$ When we look at the host portion
