How this service works
A record of ci.<domain>: looks up the ci 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 ci without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the ci.<domain> A record exists, the resolved IPv4 address(es), the TTL in seconds, and the DNS response code (e.g. NOERROR or NXDOMAIN), as answered by Cloudflare DNS over HTTPS.
Example use cases
Verify CI infrastructure for a domain
“Does ci.gitlab.com exist as a DNS A record? I want to know its IPv4 address and TTL.”
Pre-deployment subdomain sanity check
“Before I deploy, can you confirm that ci.mycompany.io resolves — check its A record and tell me if it's live.”
Competitor infrastructure recon
“I'm researching whether competitor.com has a CI server exposed — can you check if ci.competitor.com has a DNS A record?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/ci/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, focused existence check for the ci subdomain of a specific domain without enumerating all subdomains. Prefer it over generic DNS tools when you specifically want Cloudflare DoH resolution for the ci host and need TTL data alongside the IP. It is ideal for DevOps agents verifying CI infrastructure presence or reconnaissance workflows targeting common known hostnames.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- ci subdomain not configured — NXDOMAIN with empty record set
- Invalid domain input — may return error or empty response
- Network/DoH resolver timeout — request fails with no data
- Malformed domain string — request may return error response
