of hosts on that network, and the directed broadcast address for that network.

You have been given 10.50.56.0/22 as your network. You want to subnet this
to some number of subnets with upto 250 hosts in each. What is the netmask
for the subnet, and what are the available subnet numbers?
You have been given 10.50.50.0/24 as your network. You want to divide
this up into a a set of subnets such that 2 subnets will have up to 60 hosts,
and 2 subnets will have upto 25 hosts, and 2 subnets will be point to point
links with just two hosts. Show the new networks/netmasks you create and the
range of hosts you can assign to each.
