How It Works
Report Malicious IPs
Spot an abusive IP? Report it in seconds — no account needed. Add the category, description, and evidence. The IP's country is detected automatically.
Community Validates
Multiple reports on the same IP raise its threat level. Under 10 reports shows as orange; 10 or more flags it red as high-threat. Crowd-sourced accuracy at scale.
