How this service works
A record of internal.<domain>: looks up the internal 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 internal without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the 'internal.<domain>' hostname exists in DNS, its A record IP address(es), the TTL value, and the DNS response code — all resolved via Cloudflare DNS over HTTPS.
Example use cases
Pre-deployment internal host check
“Before we launch, can you verify that internal.mycompany.com has a valid A record in DNS and tell me the IP and TTL it's returning?”
Security audit for exposed internal hosts
“As part of a quick security review, check whether internal.targetdomain.com resolves publicly — does it have an A record and if so what IP does it point to?”
Infrastructure existence verification
“I'm setting up a monitoring config — can you confirm whether internal.rally.ca actually exists in DNS and what its current A record looks like?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/internal/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, single-shot existence and resolution check specifically for the 'internal' subdomain of a given domain, without needing to enumerate all subdomains. Prefer it over general DNS A record endpoints when the target host is known to be 'internal' and you want a pre-scoped, cheap lookup via Cloudflare DoH.
Side effects
- Domain not found / NXDOMAIN — internal subdomain does not exist under the given domain
- Invalid domain input — malformed domain name rejected
- Cloudflare DoH upstream timeout or error — DNS resolution fails
- Payment failure — x402 micropayment not completed, request not processed
