How this service works
Is this IPv4 address announced by alibaba? Resolves the address to its origin ASN (Team Cymru DNS) and compares with alibaba's known autonomous systems (AS45102, AS37963, AS24429), returning yes/no with the ASN, prefix and network name. Fraud scoring, allow-listing and infrastructure mapping. $0.01 per lookup.
Output
Returns a yes/no answer indicating whether the IPv4 address belongs to Alibaba's autonomous systems, along with the resolved ASN number, the IP prefix/subnet it falls under, and the network name associated with that ASN.
Example use cases
Fraud scoring for incoming requests
“We're seeing a spike in signups from the IP 47.89.45.200 — can you check if it's coming from Alibaba's cloud infrastructure so I can decide whether to flag it as suspicious?”
Firewall allow-list for Alibaba traffic
“I need to verify if 203.107.54.3 is an Alibaba IP before I add it to our allow-list — can you check which ASN it belongs to and confirm it's one of Alibaba's networks?”
Cloud provider attribution for infrastructure mapping
“We're building a map of which cloud providers our partners are using — can you look up 101.37.182.10 and tell me if it's announced by Alibaba, along with the ASN and network prefix?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/is/alibaba?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to determine if an IP belongs to Alibaba's cloud infrastructure (AS45102, AS37963, AS24429) with authoritative ASN-level resolution via Team Cymru DNS. It is purpose-built for Alibaba detection with a flat $0.01 per-call price, making it ideal for high-volume fraud scoring, allow/block-listing, and cloud provider attribution workflows where Alibaba-specific ASN data is required.
Side effects
- Invalid or malformed IPv4 address input returns an error
- Private or reserved IP addresses (RFC1918) may not resolve to a public ASN
- Team Cymru DNS resolution failures may cause lookup timeouts
- IP addresses not yet in BGP routing tables return no ASN data
- Payment failure (insufficient USDC balance) blocks the request
