How this service works
A record of new.<domain>: looks up the new 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 new without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the A record for new.<domain> exists, the resolved IP address(es), the TTL of the record, and metadata about the DNS response as answered by Cloudflare DoH.
Example use cases
Verify new portal subdomain exists
“Does new.shopify.com have a DNS A record? I want to know if they've set up a 'new' subdomain and what IP it resolves to.”
Competitor infrastructure reconnaissance
“Check whether new.notion.so resolves — I'm trying to figure out if Notion has a 'new' onboarding or product subdomain live in DNS.”
Pre-deployment DNS confirmation
“We just configured new.mycompany.com in our DNS — can you confirm the A record is live and tell me the TTL and IP it's returning?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/new/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-purpose check of whether the 'new' subdomain of a specific domain resolves via A record, without needing to enumerate all subdomains. Prefer it over general DNS tools when you specifically want the 'new' host and want a pre-built, pay-per-call microservice backed by Cloudflare DoH for reliability.
Side effects
- Domain does not exist or has no DNS records — returns NXDOMAIN or empty result
- new.<domain> exists in DNS but has no A record (e.g. only CNAME or AAAA) — returns empty A record set
- Network or Cloudflare DoH upstream timeout — returns error response
- Malformed or missing domain input — returns 400-level error
- SERVFAIL from upstream resolver — propagated as error in response
