How this service works
A record of m.<domain>: looks up the m 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 m without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the m.<domain> A record exists, the resolved IPv4 address(es), the TTL in seconds, and the DNS response code. If the subdomain does not exist, indicates its absence without enumerating other subdomains.
Example use cases
Mobile subdomain existence check
“Does twitter.com have an m subdomain set up? I want to know if m.twitter.com resolves to an IP and what the TTL is.”
Brand domain infrastructure audit
“I'm auditing shopify.com's DNS setup — can you check whether m.shopify.com has an A record and what IP it points to?”
Competitor mobile presence research
“I'm researching whether our competitor bestbuy.com still uses a separate mobile subdomain — can you look up the A record for m.bestbuy.com and tell me if it exists?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/m/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted existence and resolution check specifically for the 'm' subdomain (commonly used for mobile sites) of a given domain, without triggering full subdomain enumeration. Prefer this over general DNS A-record lookups when the specific host of interest is 'm' and you want Cloudflare DoH resolution. It is pay-per-use at $0.01 USDC, making it cost-effective for spot checks.
Side effects
- Domain does not exist (NXDOMAIN) — returns non-existence status
- m subdomain not configured — returns no records found
- Invalid domain format provided — may return error or empty result
- Cloudflare DoH upstream timeout — may result in delayed or failed response
- Network connectivity issue to dns.intel.rallylive.ca — endpoint unavailable
