How this service works
Bulk is dns hosted by 1and1: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
Returns an ordered array of results matching the input domain list. Each item indicates whether that domain's NS records resolve to 1&1 (IONOS) nameservers (true/false), includes a per-item error field if the lookup failed, and the overall response includes a count of how many items failed.
Example use cases
Audit domain portfolio for 1and1 DNS
“I have a list of 18 client domains and I need to know which ones are currently using 1&1 IONOS for their DNS hosting — can you run them all at once and give me the results in order?”
Pre-migration DNS provider sweep
“Before we migrate DNS, check these 12 domains to see if any of them are still hosted on 1&1 nameservers so we know which ones need to be moved.”
Competitor infrastructure research
“I'm researching DNS hosting choices across a set of 20 competitor domains — can you tell me which of them are using 1&1 IONOS for DNS in a single batch lookup?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/bulk/dns/hosted-by/1and1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check more than one domain at a time for 1&1 DNS hosting — it processes up to 20 domains concurrently in a single $0.10 USDC call, which is far more efficient than calling the single-domain endpoint repeatedly. Prefer this for batch enrichment workflows, portfolio audits, or any pipeline where you hold a list of domains. If you only need to check one domain, the single-item sibling endpoint avoids the batch overhead.
Side effects
- Input list exceeds 20 domains — batch limit enforced
- Individual domain DNS lookup fails — reflected in per-item error field and increments failure count
- Malformed domain name in input — per-item error returned
- DNS resolution timeout for a specific domain — counted as failure with error detail
- Payment not provided or invalid — 402 response, no results returned
