How this service works
Is the domain's DNS hosted by 1and1? Looks up the NS records (Cloudflare DoH) and matches them against 1and1's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.
Output
Returns a yes/no indicator of whether the domain's DNS is hosted by 1&1 (IONOS), the full list of NS records retrieved via Cloudflare DoH, and specifically which nameservers matched known 1&1 nameserver patterns.
Example use cases
Sales prospecting for 1and1 customers
“I'm building a list of potential leads still using 1and1 for DNS hosting — can you check if riverpineconsulting.com is hosted by 1and1 and tell me which nameservers matched?”
Pre-migration DNS vendor audit
“Before we migrate clientdomain.com to Cloudflare, can you confirm whether their DNS is currently hosted by 1and1 and show me their nameservers?”
Security vendor detection sweep
“As part of our security review, I need to know if partnerbrand.com uses 1and1 for DNS hosting — check their NS records and let me know if any match 1and1's patterns.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/1and1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost ($0.01) single-domain check specifically for 1&1 IONOS DNS hosting detection, using Cloudflare DoH for reliable NS lookups. Ideal for sales intelligence pipelines, pre-migration audits, or security reviews where 1and1 vendor identification is the specific goal. Prefer this over generic DNS lookup tools when you need the matched/unmatched nameserver output in a structured yes/no format.
Side effects
- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH is temporarily unavailable — lookup fails with a connectivity or upstream error
- Invalid or malformed domain name input — returns an error or no result
- Domain uses 1and1 hosting but with custom/white-label nameservers not matching known patterns — false negative
