1: The first octet rule says that the highest class C address is 223, but it is known that for eight bits the highest decimal number is 255. There are two more classes: Class D addresses are for multicast, and class E addresses are for experimental usage. Class D addresses have, as their first four bits, 1110. What is the decimal range of the first octet of class D addresses?
2: Select a subnet mask for 10.0.0.0 so that there will be at least 16,000 subnets with at least 700 host addresses available on each subnet. Select a subnet mask for 172.27.0.0 so that there are at least 500 subnets with at least 100 host addresses available on each subnet.
3: How many subnets are available if a class C address has six bits of subnetting? ...
