Why check an IP reputation?

To verify if an IP is blacklisted before sending emails, to investigate suspicious traffic sources, or to check if your server IP has been flagged by security databases.

What databases does this tool check?

This tool queries major threat intelligence databases including Spamhaus, SURBL, Barracuda, Sorbs and other leading IP reputation services.

What should I do if my IP is blacklisted?

Contact the blacklisting service and follow their delisting process. Identify and fix the root cause (spam, malware, open relay) before requesting removal.

What is IP reputation?+

IP reputation is a score that reflects the trustworthiness of an IP address based on its history of abuse, spam sending, hacking attempts, malware distribution and other malicious activity. ISPs, email providers and security systems use reputation scores to decide whether to block or rate-limit traffic.

What does the abuse confidence score mean?+

The abuse confidence score (0–100) represents how likely an IP is to be malicious based on reports from the security community. A score of 0 means no known abuse. Scores above 25 are suspicious. Scores above 75 indicate a high probability of malicious activity.

Why is my IP showing as a VPN or proxy?+

If you use a VPN, your traffic exits from a VPN server IP. These IPs are often flagged as VPN or proxy in threat intelligence databases because many different users share them. This does not mean the IP is malicious — but it can affect services that block VPN traffic.

What should I do if my IP has a bad reputation?+

Check with your ISP — your IP may have been previously assigned to another user who used it maliciously. Submit abuse reports to AbuseIPDB and similar services to have false flags reviewed. For businesses, contact your hosting provider about IP reputation remediation.

What is IP Reputation?

IP reputation is a score, maintained by security vendors and blocklist services, reflecting how much malicious activity — spam, malware distribution, brute-force login attempts — has historically been associated with a given IP address.

Why Check IP Reputation?

A poor reputation score can mean your emails get marked as spam, your server gets blocked by firewalls, or visitors from that IP get extra scrutiny — checking reputation helps diagnose delivery or access problems, or vet an IP before trusting traffic from it.

How to Read the Results

The tool checks the target IP against multiple reputation and blocklist databases, showing which, if any, have flagged it and why — a clean result across all lists is a good sign, while flags on multiple lists warrant investigating what’s actually happening on that IP.
