Some packets arrive. Some get lost. Some were never there. GhostPacket falls into the third category. No confirmed origin, no reliable destination, no tracking number and definitely no return address. Occasionally visible, frequently questionable, usually harmless. Traceroute failed. Ping intermittent. Current location: disputed. Current objective: unknown. If you think you've seen GhostPacket before, you probably haven't. And if you did... no you didn't. GhostPacket was here. Probably.
