IP Reputation

IP reputation is an algorithmic metric that network firewalls and edge CDNs assign to an IP address, evaluating its historical traffic behavior, Autonomous System Number (ASN) category, and threat database records. When examining what is ip reputation, imagine a commercial credit score for network addresses: consistent, predictable, and compliant interaction history establishes high credibility, whereas sudden aggressive spikes or abuse reports degrade standing. Web servers assess this trust rating at the edge during initial TCP and TLS handshakes to determine how to handle incoming traffic.
