Question 6

What is the network of 128.17.21.2/17?

Answer 6

128.17.0.0, this is because 255.255.128.0 is the subnet, only leaving the first two octets all 1s. Making 128.17.0.0 the network number, and the 128 part of the subnet the next network number. This also means that the range of hosts would begin there as well. The subnet range seems to be the primary aspect of the network range, not the network number itself. The IP range for 10.249.0.1 is also 10.248.0.1-10.255.255.255 and begins at network 10.248.0.0
