How this service works
CNAME record of mx2.<domain>: looks up the mx2 host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like mx2 without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the mx2 CNAME record exists for the given domain, the CNAME record value(s), the TTL, and the DNS response code — sourced via Cloudflare DNS over HTTPS.
Example use cases
Email infrastructure audit
“I need to know if mx2.acmecorp.com has a CNAME record set up — can you check what it resolves to and tell me the TTL?”
Mail host existence check before migration
“Before we migrate our mail servers, can you verify whether mx2.oldcompany.com actually has a CNAME record configured, or does it not exist at all?”
Third-party domain onboarding verification
“We're onboarding a partner domain — can you confirm that mx2.partnerdomain.io has a CNAME record and what it's pointing to?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/mx2/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted CNAME existence check for the mx2 subdomain specifically, without enumerating all subdomains. Prefer it over general DNS lookup tools when you want Cloudflare DoH resolution semantics and need a low-cost ($0.01) single-host check for mx2 mail host configuration.
Side effects
- Domain not provided — request rejected with missing parameter error
- mx2 subdomain does not exist — returns NXDOMAIN or empty record set
- Cloudflare DoH upstream timeout — service may return error or partial response
- Invalid domain format — may return error or no records
- Network connectivity issues to Cloudflare DoH — lookup fails
