DNSLens
Free DNS Lookup & Propagation Checker for Android
Query any DNS record type across multiple public resolvers — all from your phone. Check propagation, browse record details, and save lookup history. No account required, no data collected.
Features
All Record Types
Query A, AAAA, MX, CNAME, TXT, NS, SOA, SRV, and PTR records. Color-coded type badges for easy scanning.
Propagation Check
Compare DNS results across Google (8.8.8.8), Cloudflare (1.1.1.1), Quad9 (9.9.9.9), and OpenDNS (208.67.222.222).
Record Filtering
Filter results by record type with chips. Each type gets a unique Catppuccin accent color for visual clarity.
Lookup History
All lookups saved locally with timestamps, record types found, and result counts. Clear anytime.
Fast Queries
Powered by dnsjava for reliable, fast lookups. Results return in milliseconds with response time tracking.
Match Detection
Propagation checker shows MATCH/DIFFER/ERROR status for each resolver so you know if DNS has fully propagated.
Dark Theme
Beautiful Catppuccin Mocha dark theme. Easy on the eyes for late-night DNS debugging.
Privacy First
Domain validation prevents injection. No data leaves your device except DNS queries to public resolvers.
Lightweight
Small APK, low memory usage, no background processes. Just a fast DNS tool when you need it.
