Record types
- A — IPv4 address (most common, maps domain to IP)
- AAAA — IPv6 address
- MX — mail exchange (which servers receive email for the domain)
- TXT — text records (SPF, DKIM, domain verification, ownership proof)
- NS — name servers (authoritative DNS for the domain)
- CNAME — canonical name alias (redirect to another domain)
- SOA — start of authority (zone admin info, refresh intervals)
- CAA — certificate authority authorization (which CAs can issue certs)
- SRV — service location (used by VoIP, Matrix, etc.)
How it works
- Queries are sent via DNS-over-HTTPS (DoH) to Cloudflare or Google resolvers
- No server-side proxy needed — runs entirely in your browser
- Results show TTL (cache lifetime in seconds) and the raw record data
