Frequently Asked Questions

What is IP reputation and why should I check it?

IP reputation indicates whether an IP address has been associated with malicious activities like hacking attempts, spam, or cyber attacks. Checking IP reputation helps identify potential threats before they compromise your systems. Combine this tool with Blacklist Checker to verify email reputation and use What is My IP to check your own server's public IP address.

How do I interpret the threat levels?

AbuseIPDB categorizes IPs into three threat levels based on abuse confidence score: Safe (1) means no malicious activity detected (0% score), Suspicious (2) indicates some concerning behavior (1-25% score), and Malicious (3) confirms active attack patterns (26-100% score). Always investigate suspicious IPs further using Port Scanner to check for open vulnerabilities and security misconfigurations.

What should I do if an IP is marked as malicious?

If an IP is flagged as malicious, immediately block it at your firewall level, review server logs for any successful intrusions, and investigate the IP's history using WHOIS Lookup to identify the source. Document the incident and consider reporting persistent attackers to your hosting provider or appropriate authorities.

How can I protect my VPS from malicious IPs?

Implement strong firewall rules, use fail2ban or similar intrusion prevention systems, keep software updated, and regularly monitor access logs. Choose VPS providers with built-in DDoS protection and security features. Check our VPS benchmarks for security-focused providers or compare options in our VPS provider comparisons to find hosting with robust security infrastructure.
