DNSAudit.io is a free, web-based DNS security scanner that analyzes the external DNS configuration of any domain and produces a scored security report. How it works: - A user enters any domain name and initiates a scan - The tool performs 40+ automated DNS checks against the domain's publicly visible DNS records - Results are returned in seconds with a letter grade (A+ through F) and a list of findings What it checks: Standard DNS record validation: - A, AAAA, MX, NS, CNAME, and TXT records - SPF and DMARC configuration - DKIM key structure - DNSSEC status Misconfiguration and unsafe pattern detection: - Zone transfer exposure - Wildcard DNS misconfiguration - Open resolver detection - DNS rebinding risks - Amplification vectors - Missing security headers in TXT records Attack surface and threat exposure: - AI infrastructure exposure patterns - IPs linked to botnets or malware - Suspicious TXT record payloads - Dangerous CDN configurations - Cloud storage references in DNS records - Passive DNS threat correlation Output: - A DNS security score and letter grade - A breakdown of what is exposed or misconfigured - Actionable remediation guidance The tool requires no account registration and is designed for quick, frictionless use. It maintains a public leaderboard of recently scanned domains, top-scoring domains, and lowest-scoring domains. Checks are updated regularly to reflect new threats and misconfiguration patterns.
