It means the IP has appeared in one or more threat intelligence blacklist datasets, indicating that it has been associated with abusive or malicious activity such as spam, scanning, botnet traffic or malware hosting.
It indicates that the IP was added to blacklist feeds very recently. Fresh blacklist entries often point to active or emerging malicious infrastructure that has just begun operating.
It means the IP has stayed in blacklist datasets for an extended period or repeatedly reappears over time. Long-term or persistent blacklist presence strongly suggests chronic abuse or infrastructure intentionally used for malicious operations.
