1--- Part Two --- 2 3Packets sent to address 255 are handled by a device called a NAT (Not Always Transmitting). The NAT 4is responsible for managing power consumption of the network by blocking certain packets and 5watching for idle periods in the computers. 6 7If a packet would be sent to address 255, the NAT receives it instead. The NAT remembers only the 8[1m[97mlast[0m packet it receives; that is, the data in each packet it receives overwrites the NAT's packet 9memory with the new packet's X and Y values. 10 11The NAT also monitors all computers on the network. If all computers have [1m[97mempty incoming packet 12queues[0m and are [1m[97mcontinuously trying to receive packets[0m without sending packets, the network is 13considered [1m[97midle[0m. 14 15Once the network is idle, the NAT sends [1m[97monly the last packet it received[0m to address 0; this will 16cause the computers on the network to resume activity. In this way, the NAT can throttle power 17consumption of the network when the ship needs power in other areas. 18 19Monitor packets released to the computer at address 0 by the NAT. [1m[97mWhat is the first Y value 20delivered by the NAT to the computer at address 0 twice in a row?[0m 21 22
