How this service works
Is the domain's DNS hosted by alibaba? Looks up the NS records (Cloudflare DoH) and matches them against alibaba'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 Alibaba, the full list of NS records retrieved via Cloudflare DoH, and the subset of nameservers that matched Alibaba's known nameserver patterns.
Example use cases
Sales prospecting for Alibaba Cloud customers
“I'm building a list of companies that use Alibaba Cloud infrastructure. Can you check whether acme-corp.com has its DNS hosted by Alibaba and tell me which nameservers matched?”
Security audit for third-party DNS exposure
“We're doing a vendor risk review — can you check if vendor-domain.io is using Alibaba-hosted DNS? I need to know yes or no and see the actual nameservers.”
Pre-migration DNS provider verification
“Before we start the migration project, can you confirm whether target-company.com is currently on Alibaba DNS? I want the list of nameservers and which ones are Alibaba's.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/alibaba?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically determine whether a specific domain's DNS is managed by Alibaba Cloud, particularly for sales intelligence (finding Alibaba customers), security assessments (mapping vendor infrastructure), or pre-migration audits. It is more specific than a generic NS lookup because it performs the Alibaba pattern-matching logic for you. Prefer the sibling AWS Route 53 endpoint if you need to check for Amazon DNS instead.
Side effects
- Domain does not exist or has no NS records — returns empty result or NXDOMAIN
- Cloudflare DoH unreachable — lookup fails with a connectivity error
- Domain uses Alibaba DNS under an unrecognized pattern — false negative (not matched)
- Invalid domain format provided — request rejected
- Rate limiting or payment failure — 402 response if USDC payment not attached
