Empowering Developers, Sysadmins & Domain Owners with Real-Time DNS Clarity
DNS Info (dnsinfo.live) was engineered to solve one of the web's most pervasive operational headaches: DNS uncertainty. We provide ultra-fast, uncensored, and authoritative domain diagnostics across global resolvers—completely free and without logging your confidential searches.
Strategic edge vantage points verifying propagation worldwide
From IPv4/IPv6 to modern HTTP/3, SVCB, and DNSSEC keys
Zero stale caching. Live root, TLD, and authoritative nameserver queries
Privacy-first design. We never sell, log, or commercialize your lookup data
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
Core DNS Record Lookups
Instant authoritative resolution for all standard internet protocol records with sub-second response times.
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 simultaneously 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.
