About DNS Info
Independent, real-time DNS resolution, global propagation tracking, and email deliverability intelligence built for developers, system administrators, and domain owners.
Multi-region propagation testing across 8 world locations
Authoritative lookups from A, AAAA, and MX to modern HTTPS, SVCB, and DNSSEC
Direct queries to authoritative nameservers without cached middleman responses
Queries are resolved in memory and never logged, tracked, or sold
Why technical teams rely on DNS Info
Raw Diagnostic Accuracy
We don't mask technical responses behind vague status indicators. We display raw SOA serial numbers, TTL countdowns, authoritative answer flags, and exact routing IP addresses so you can diagnose configuration issues instantly.
Deep Email Authentication
Modern mailbox providers (Google, Microsoft, Yahoo) strictly enforce authentication. Our engines perform recursive SPF include expansion (detecting the RFC 7208 10-lookup limit), DKIM key verification, and DMARC enforcement auditing.
Uncompromising Privacy
Your domain lookup queries belong to you. We evaluate queries in memory and do not harvest search queries, build user dossiers, or sell lookup history to competitors or data brokers.
Everything You need to Diagnose & Protect Domains
Email Security & Deliverability
Prevent email spoofing, phishing, and domain impersonation while ensuring messages land in the inbox.
Multi-Region Propagation Checker
Query authoritative and recursive resolvers worldwide across 8 global regions to track record propagation after DNS changes.
Network & Platform Diagnostics
Verify host reachability, packet round-trip times, network routing hops, firewall port states, and TLS certificates.
Designed for those who keep the internet running
Software Developers
Verify DNS resolution before shipping, validate API hostnames, and debug CNAME alias chains.
Sysadmins & DevOps
Execute zero-downtime server migrations, monitor nameserver synchronization, and audit TTL values.
Email Administrators
Ensure SPF, DKIM, and DMARC alignments meet Google and Microsoft inbox deliverability standards.
Security Auditors
Confirm DNSSEC cryptographic chain of trust, CAA certificate constraints, and blacklisted IP ranges.
