Question: What is the number of networks when the size of rest bit field is 8?
SQL: SELECT "number_of_networks" FROM classful_networks WHERE "size_of_rest_bit_field" = '8'

Question: What is the start address when the network number bit field is 16?
SQL: SELECT "start_address" FROM classful_networks WHERE "size_of_network_number_bit_field" = '16'

Question: What is the end address for the Class E (Reserved)?
SQL: SELECT "end_address" FROM classful_networks WHERE "class" = 'class e (reserved)'

Question: What is the size of the rest bit field when the leading bits are more than 110 and the start address is 224.0.0.0?
SQL: SELECT "size_of_rest_bit_field" FROM classful_networks WHERE "leading_bits" > 110 AND "start_address" = '224.0.0.0'
