How this service works
MX records for a domain as answered by Cloudflare 1.1.1.1 (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.
Output
Returns the MX records (priority and mail server hostnames) for the queried domain as answered by Cloudflare 1.1.1.1, including the TTL, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time in milliseconds.
Example use cases
Email delivery troubleshooting
“My emails to clients at acmecorp.com are bouncing — can you check what MX records Cloudflare 1.1.1.1 returns for acmecorp.com and whether they look correct?”
DNS propagation verification
“I just updated the MX records for mybusiness.com — can you check whether Cloudflare 1.1.1.1 has picked up the new records yet and what TTL they're showing?”
Resolver comparison for split-horizon detection
“Can you pull the MX records for payments.example.com from Cloudflare 1.1.1.1 so I can compare them against what another resolver is returning and see if there's a split-horizon answer?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/mx/via/cloudflare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to know what MX records Cloudflare 1.1.1.1 reports for a domain — ideal for diagnosing email delivery issues, verifying DNS propagation as seen from Cloudflare's global network, checking DNSSEC validation status, or comparing Cloudflare's answer against other resolvers to detect split-horizon DNS or propagation lag. Prefer this over general DNS lookup tools when you need structured programmatic output including TTL, response code, DNSSEC flag, and resolver latency together in one response.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- Domain exists but has no MX records — returns NOERROR with empty answer set
- Resolver upstream failure — returns SERVFAIL response code
- Invalid domain name input — may return error or NXDOMAIN
- Network timeout reaching Cloudflare DoH endpoint — may return a service error
