How this service works
A record of support.<domain>: looks up the support host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like support without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the support.<domain> A record exists, its IPv4 address(es), and the TTL value for the record as resolved via Cloudflare DoH.
Example use cases
Verify support portal existence
“Does support.stripe.com actually exist as a real host? Look up its DNS A record and tell me the IP address and TTL.”
Pre-contact infrastructure check
“Before I reach out to their support team, can you check whether support.hubspot.com is a live host by resolving its A record?”
Onboarding domain validation
“We just onboarded a new customer with domain clientbrand.com — can you check if their support subdomain exists by looking up the A record for support.clientbrand.com?”
