Summary

Autonomous System Number (ASN) lookup identifies the network operator behind an IP address, offering more stable and informative context than IP geolocation alone for fraud detection. By assessing an ASN’s type, location, reputation, history, and links to data centers, anonymization services, botnets, or suspicious hosting, organizations can assign risk scores to user activity and decide whether to allow, challenge, or block access or transactions. ASN analysis can help identify proxy abuse, account takeovers, card-not-present fraud, spam, phishing, and coordinated botnet activity, particularly when unusual traffic patterns or high-risk networks are detected. Its effectiveness is strongest when combined with signals such as device fingerprinting, behavioral biometrics, and velocity checks, rather than used as a standalone control. Didit presents its platform as a fraud prevention solution that integrates real-time ASN intelligence, customizable reputation-based rules, and other detection signals to flag suspicious activity.
