How this service works
AAAA record of secure.<domain>: looks up the secure 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 secure without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the 'secure.<domain>' AAAA record exists, the IPv6 address(es) in the record, and the associated TTL value. If the record does not exist, the response indicates non-existence.
Example use cases
IPv6 readiness check for secure host
“Can you look up whether secure.mycompany.com has an AAAA record? I want to know if that subdomain is reachable over IPv6.”
Verify secure subdomain before deployment
“Before we go live, check if secure.newstartup.io has an existing AAAA DNS record — I need to know the IPv6 address and TTL if it's there.”
Audit domain infrastructure for IPv6 support
“Does secure.legacybank.com exist in DNS as an AAAA record? We're auditing which of our domains have IPv6 configured on the secure subdomain.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/secure/aaaa?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-purpose IPv6 DNS existence check specifically for the 'secure' subdomain of a domain, without needing to enumerate all subdomains or resolve other record types. Ideal for infrastructure audits, deployment pre-checks, or verifying IPv6 reachability of a known common host pattern.
Side effects
- Domain not found or NXDOMAIN — returns no records with existence flag false
- Malformed domain input — may return an error or empty result
- Upstream Cloudflare DoH unavailable — request times out or fails
- Domain has no AAAA record for 'secure' subdomain — returns empty record set
- Payment not processed — 402 response blocking the lookup
