Question: What is the number of networks if the size of the remainder bit field for a class-related network is 8?

Question: What is the starting address from the classful network when the network number bitfield is 16?

Question: What is the end address for class E (reserved) on the classful network?

Question: Considering the classful network: what is the size of the residual bit field if the leading bits are more than 110 and the starting address is 224.0.0.0?
