What this tool does
MX Atlas runs on Cloudflare Workers. It requests your selected DNS record type from Cloudflare or Google and presents values, TTL, type-specific fields and the resolver’s authenticated-data flag. The common-records overview makes eight separate queries; it is not a complete zone export. You can copy results, export JSON or share a lookup link.
How we interpret results
Our guides reference DNS-provider documentation and IETF standards. Examples are labeled, and lookup results come from actual DNS responses. Missing MX, Null MX, nonexistent names and resolver failures are handled separately.
An independent service
MX Atlas is operated independently by the site owner and is not affiliated with or endorsed by OpenAI, ChatGPT, Google or Cloudflare. The service is free and supported by advertising. DNS queries are not mail-delivery tests, and availability is not guaranteed.
