How this service works
A record of staging.<domain>: looks up the staging 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 staging without enumerating subdomains. $0.01 per lookup.
Output
Returns whether staging.<domain> exists in DNS, its A record IP address(es), the TTL in seconds, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
Example use cases
Verify staging environment is live
“Before I deploy, can you confirm that staging.myapp.io has a valid A record and tell me what IP it resolves to?”
Debug misconfigured staging DNS
“Our team says staging.example.com is unreachable — can you check whether there's an A record for it in DNS, and what the TTL is?”
Pre-launch subdomain existence check
“We're onboarding a new client at clientco.com — can you quickly check if staging.clientco.com exists in DNS so we know if they already have a staging environment set up?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/staging/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-shot existence and IP check for the staging subdomain of a known domain without doing broad subdomain enumeration. Prefer it over generic DNS resolvers when you specifically want Cloudflare DoH resolution semantics and a simple pay-per-lookup model. It's ideal for DevOps automation, pre-deployment checks, or client onboarding workflows.
Side effects
- Domain does not exist — NXDOMAIN returned, no A records
- staging subdomain not configured — NXDOMAIN for subdomain even if root domain resolves
- Invalid or malformed domain input — request error
- Cloudflare DoH upstream timeout or error — service unavailable
- Domain exists but has no A record (only CNAME or other types) — empty record set
