Problems

$1.$ Define subnet mask for entire network

$2.$ Document subnet numbers for all subnets $($A thru Q$)$

$3.$ Define range of valid IP addresses for all subnets

$4.$ Document all router interface$$s IP addresses

$5.$ Route tables $($on Routers only$)$

Suggested Steps

$1.$ 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 of the address how many bits are we looking at$?$

$-$ Range of valid addresses starts with ALL OFF$$S $+1->$ ALL ON$$S $1$

$4.$ Based on this range, you need to define all your router interfaces

$5.$ Then configure your route table for routers II and V$).$ The routers should have entries for all subnets in every route table.
