How this service works
AAAA record of owa.<domain>: looks up the owa host under the domain you give (AAAA 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> AAAA record exists, the resolved IPv6 address(es) if present, the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN).
Example use cases
Detect OWA server on target domain
“Does microsoft365customer.com have an owa subdomain with an IPv6 record? I'm trying to find out if they're running Outlook Web Access.”
Pre-deployment IPv6 check for OWA
“Before we go live, can you confirm that owa.ourcompany.com has a valid AAAA record and what the TTL is?”
OSINT recon for email infrastructure
“I'm doing recon on targetorg.com — can you check if their owa subdomain exists and resolves to any IPv6 addresses?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/owa/aaaa?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for whether a specific domain has an owa subdomain with IPv6 (AAAA) DNS records, without running a full subdomain enumeration. Ideal for OSINT, infrastructure discovery, or verifying Outlook Web Access deployments on specific domains.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- owa subdomain not configured — NXDOMAIN or empty answer section
- Network or DoH resolver timeout — no response returned
- Invalid domain format in input — request may fail or return error
- Cloudflare DoH unavailable — service temporarily unreachable
