How this service works
A record of mobile.<domain>: looks up the mobile 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 mobile without enumerating subdomains. $0.01 per lookup.
Output
Returns whether mobile.<domain> exists in DNS, its A record IP address(es), and the TTL of those records, sourced from Cloudflare DNS-over-HTTPS. If the host does not exist, the response indicates a non-existence result (e.g. NXDOMAIN).
Example use cases
Verify mobile subdomain before redirect
“Check if mobile.mystore.com has an A record — I need to know if it exists and what IP it points to before setting up my redirect rules.”
Audit competitor mobile presence
“Does tesla.com have a mobile subdomain? Look up the A record for mobile.tesla.com and tell me the IP and TTL if it exists.”
Monitor infrastructure existence check
“I want to confirm whether mobile.acmecorp.com is currently live in DNS — can you resolve its A record via Cloudflare and tell me if it's there?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/mobile/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap ($0.01) existence check specifically for the 'mobile' subdomain of a domain, without needing to enumerate all subdomains. Prefer it over generic DNS tools when you only care about the mobile host and want Cloudflare's authoritative DoH resolution.
Side effects
- Domain does not exist (NXDOMAIN) — returns no records and non-existence status
- mobile subdomain not configured — returns empty record set
- Network timeout reaching Cloudflare DoH — service error
- Invalid domain input format — malformed request error
- Cloudflare DoH returns SERVFAIL for the queried name
