How this service works
A record of owa.<domain>: looks up the owa 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 owa without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the owa.<domain> A record exists, the resolved IPv4 address(es), the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN), as answered by Cloudflare DoH.
Example use cases
Exchange server discovery for IT audit
“We're auditing contoso.com's email infrastructure — can you check if owa.contoso.com has a DNS A record and what IP it points to?”
Pre-migration OWA host verification
“Before we migrate away from on-prem Exchange, check if owa.acmecorp.com is still live in DNS and what its current A record and TTL are.”
Security recon for known domain
“I need to know if the company targetbrand.com has an Outlook Web Access portal exposed — can you look up the A record for owa.targetbrand.com?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/owa/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted check for the presence and IPv4 address of the OWA (Outlook Web Access) subdomain specifically, without enumerating all subdomains. Prefer it over general DNS tools when you only care about the owa host and want a lightweight, pay-per-lookup DNS check via Cloudflare DoH.
Side effects
- NXDOMAIN response when owa subdomain does not exist for the given domain
- Invalid or malformed domain name input returns an error
- Network or DoH resolver timeout
- Domain exists but owa host has no A record (may have CNAME or other record types instead)
