An IP reputation checker looks up an IP address or domain name against threat intelligence databases to determine whether it has been associated with malicious activity. ShieldScan queries VirusTotal's network of 95+ security vendors to return a comprehensive reputation report — including threat history, category, geolocation, and ISP — in seconds.
IP reputation is used by security teams to identify malicious servers, spam sources, botnet nodes, and phishing infrastructure. When an IP address appears in your firewall logs, email headers, or network traffic, checking its reputation can quickly determine whether the connection is a threat or legitimate — without deep packet inspection or manual investigation.
Enter the domain name in ShieldScan's IP/Domain checker. ShieldScan queries it against VirusTotal's 95+ security vendor database, which includes multiple blacklists and threat intelligence feeds. If the domain is blacklisted by any vendors, you'll see exactly which ones flagged it and what category of threat (malware, phishing, spam, etc.) was detected.
When you receive a suspicious email, check the originating IP address by looking at the email headers (usually found in the "View Raw" or "Show Original" option in your email client). Copy the sending server IP and paste it into ShieldScan's IP checker to see if it belongs to a known spam network, phishing operation, or malicious infrastructure.
