About IPScanner.in
A free cybersecurity intelligence platform by QuantNest Technologies
Our Mission
IPScanner.in is a cybersecurity intelligence platform built by QuantNest Technologies. We provide real-time threat analysis, network diagnostics, and security assessment tools designed for security professionals, system administrators, and developers worldwide.
Our platform consolidates multiple security tools into a single, streamlined interface — eliminating the need to juggle between disparate services when investigating threats or verifying infrastructure security.
What We Offer
- IP Reputation Scanner — Instantly check if an IP address has been flagged for abuse, spam, or malicious activity using aggregated threat intelligence feeds.
- DNS Lookup Tool — Retrieve A, MX, NS, and TXT records along with real-time domain registration data via RDAP.
- SSL Certificate Checker — Verify TLS/SSL certificate validity, inspect certificate chains, assess protocol strength, and receive a comprehensive security score.
- Email Header Analyzer — Parse and analyze email headers to detect spoofing, verify SPF/DKIM/DMARC compliance, and trace message routing.
- URL Reputation Scanner — Assess URLs for phishing, malware, and domain reputation issues before clicking.

How Our Tools Work
Each tool on IPScanner.in connects to a Cloudflare Workers edge API that aggregates data from multiple authoritative intelligence sources in real time. Responses are never cached with your query — every scan is fresh, private, and discarded after delivery.
- IP Reputation — Cross-referenced against AbuseIPDB, OTX AlienVault, and 90+ global threat feeds. Results include abuse confidence scores, ISP data, geolocation, VPN/proxy/Tor detection, and attack category classification.
- DNS Lookup — Queries authoritative nameservers directly for A, MX, NS, and TXT records alongside RDAP-based domain registration data.
- SSL Certificate Checker — Inspects the full TLS handshake: certificate chain, issuer, expiry date, protocol version (TLS 1.2/1.3), and cipher suite strength.
- Email Security Auditor — Validates SPF, DKIM, and DMARC policies against the domain's live DNS records to identify spoofing risks and deliverability gaps.
- URL Reputation Scanner — Submits URLs to VirusTotal and cross-checks against Google Safe Browsing and SURBL to detect phishing, malware, and typosquatting.
Data Sources & Intelligence Partners
The platform aggregates threat intelligence from several industry-trusted providers:
- AbuseIPDB — Community-driven database of IPs reported for malicious activity, covering SSH brute force, DDoS, port scans, and spam.
- OTX AlienVault — Open Threat Exchange platform with millions of indicators of compromise (IoCs) contributed by security researchers worldwide.
- VirusTotal — Multi-vendor URL and file scanning service aggregating results from 70+ antivirus and security engines.
- Tor Project Exit List — Official list of active Tor exit nodes, updated in real time, used to flag anonymized traffic sources.
- vpnapi.io — Specialized detection of VPN services, datacenter IPs, and anonymizing proxies.
Frequently Asked Questions
Is IPScanner.in really free to use?
Yes. All tools are free with a generous rate limit of 10 requests per minute. There are no hidden fees, no registration required, and no paywalls.
Do you log my searches?
No. We do not store or log the IP addresses, domains, or URLs you scan. Queries are processed in memory at the edge and discarded immediately after the response is sent.
How accurate is the IP reputation data?
Our data is pulled in real time from multiple authoritative feeds. Accuracy depends on the currency of the underlying intelligence databases — AbuseIPDB and OTX are updated continuously by global security contributors. For the most recent threat activity, we recommend re-scanning any IP you are actively monitoring.
Can I use this for professional security investigations?
Yes. IPScanner.in is designed to support SOC analysts, penetration testers, sysadmins, and developers in their day-to-day security workflows. The data is presented in a format suitable for quick triage as well as detailed investigation.
