Assume a "parent" network of 31.96.0.0/255.224.0.0 and a subnet mask (for a subnet we wish to create within the parent’s address space) of /15. a) What is the "parent" network’s netmask, in "slash" notation? b) If we are the network administrator for the "parent" network, how many bits can we manage? c) How many bits are available (within the parent network address space) for the subnet’s network number?
