Decoy scanning (-D) mixes forged source IPs with real scanning traffic, but too many decoys increase bandwidth consumption and the risk of detection, so it is recommended to keep the number within 50 to 100.

UnverifiedThe platform's long-term success depends on the breadth of data coverage, the accuracy of spoof detection, and whether it can continuously attract enough server listings to create network effects.63% similarUnverifiedResource exhaustion attacks (slow DoS) deplete server resources by constructing legitimately formatted but computationally expensive requests; because the request format is valid, traditional rate limiting cannot directly intercept them, requiring the application layer to identify the computational cost of individual requests and set upper limits62% similarUnverifiedEvery malicious request that reaches the origin consumes computing resources, competes with real users, triggers defensive false positives against customers, pollutes observability, and constitutes reconnaissance behavior.62% similarUnverifiedReverse DNS verification has a performance overhead (each verification requires two DNS queries); in high-traffic scenarios, it is recommended to use it in combination with IP whitelist caching.62% similar
