Comment (by madurosbus):

 CANTV does DPI for some connections, and blackhole another.
 3 stage theory.
 1. Collect information about all connections. probe later?
 2. Real-time DPI scan (fps, entropy) if thresholds triggered. Collect
 information about denied connections.
 3. Blackhole IP address if threshold for denied connections triggered.
