IP Blacklist Lookup checks whether a given IP address appears on known malicious IP blocklists. Identifies both inbound threats (attackers, spammers) and outbound threats (C2 servers, malware hosts).

The IP Blacklist Lookup API provides a simple, reliable way to integrate ip blacklist lookup functionality into your applications. Built for developers who need production-ready ip blacklist lookup capabilities without the complexity of building from scratch.
