+Packets sent to address 255 are handled by a device called a NAT (Not Always Transmitting). The NAT
+is responsible for managing power consumption of the network by blocking certain packets and
+watching for idle periods in the computers.
+
+If a packet would be sent to address 255, the NAT receives it instead.  The NAT remembers only the
+last packet it receives; that is, the data in each packet it receives overwrites the NAT's packet
+memory with the new packet's X and Y values.
+
+The NAT also monitors all computers on the network.  If all computers have empty incoming packet
+queues and are continuously trying to receive packets without sending packets, the network is
+considered idle.
+
+Once the network is idle, the NAT sends only the last packet it received to address 0; this will
+cause the computers on the network to resume activity.  In this way, the NAT can throttle power
+consumption of the network when the ship needs power in other areas.
+
+Monitor packets released to the computer at address 0 by the NAT.  What is the first Y value
+delivered by the NAT to the computer at address 0 twice in a row?
