How this service works
A record of autodiscover.<domain>: looks up the autodiscover 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 autodiscover without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the autodiscover.<domain> A record exists, the resolved IP address(es), the TTL value, and the DNS response code — allowing the caller to confirm presence, routing, and caching configuration of the autodiscover host.
Example use cases
Email client autoconfiguration check
“Check if autodiscover.acmecorp.com has an A DNS record — I'm setting up Outlook for our employees and need to confirm the autodiscover host is properly configured before troubleshooting.”
Pre-migration DNS validation
“Before we migrate to a new email provider, can you verify whether autodiscover.oldcompany.com currently resolves to an IP address and what TTL is set on that record?”
Customer domain onboarding audit
“I'm onboarding a customer with the domain techpartners.io — can you check if their autodiscover subdomain has an A record so I know if their Exchange or mail server is already configured for autoconfiguration?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/autodiscover/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted check of whether the autodiscover subdomain is configured for a specific domain, particularly for email infrastructure validation, client autoconfiguration diagnostics, or onboarding audits. Prefer this over generic DNS tools when you only care about the autodiscover host and want a structured, pre-parsed result without running your own DNS queries.
Side effects
- Domain does not exist — returns NXDOMAIN or no records found
- autodiscover subdomain not configured — returns empty record set
- Cloudflare DoH upstream timeout or error
- Malformed domain input causes query failure
- Domain uses CNAME instead of A record at autodiscover — may return no A record directly
