看到一个英文文件提到 Dark space，并且解释它是 An IP space that's not being used to connect devices to the Internet; an unused address or port number. Legitimate users rarely try to access dark space, but attackers almost always do. Generally, individual users communicate with a small number of addresses on the network. In this image, there are seven dark addresses and one lit address. The legitimate user only talks to the lit address. On the other hand, hostile scanners contact all eight. The result is that the number of distinct IP addresses a legitimate host talks to is around one address. In contrast, the scanners talk to a much higher ratio.
此外还提到 dark routes are unmonitored routes. The key to identifying dark routes is to look for asymmetric traffic flow. So, rather than looking for traffic coming and going on the same path, it's necessary to look for routes where traffic can leave one way but return another (i.e., asymmetrically).
所以这个Dark space，dark routes对应的中文应该是什么呢？
