DNSLens: DNS Lookup & Checker

DNSLens is a fast DNS lookup tool for Android. Query any domain and see every record with its TTL, check whether a DNS change has reached the major public resolvers, and verify a domain's email records in one tap.

DNS lookup
• A and AAAA (IPv4 and IPv6), MX, CNAME, TXT, NS, SOA, SRV and PTR records
• Look up all record types at once or filter to just the ones you need
• Enter an IP address for a reverse (PTR) lookup
• Color-coded record badges with human-readable TTLs

Propagation check
Query Google (8.8.8.8), Cloudflare (1.1.1.1), Quad9 (9.9.9.9) and OpenDNS side by side. See whether each answer matches, plus response times, so you know when a migration or record change is visible.

Email security check
One tap pulls the MX, SPF and DMARC records for a domain so you can check its email setup.

Workflow
• Tap any record to copy its value
• Share full results as text
• Lookup history for quick re-checks
• Domain autocomplete from past searches

For developers, sysadmins and anyone moving a domain, setting up email or troubleshooting DNS.
