Summary

Alibaba Cloud (China)

China · AI-generated

cloud hosting compute

Alibaba Cloud / Aliyun (ALIBABA-CN-NET) — the China-based network of Alibaba's cloud division, the largest cloud provider in China.

What it's used for

  • Hosting customer workloads on Alibaba Cloud within China, plus Alibaba's own services (e.g. its e-commerce platforms).

Notable

  • An IP here identifies Alibaba Cloud as the host; the workload is usually a customer's. Domestic-China traffic is subject to national filtering.
  • Distinct from AS45102, which serves Alibaba Cloud's international regions.

Interesting

  • Alibaba Cloud dominates the Chinese market much as AWS does globally, and underpins the huge traffic spikes of events like Singles' Day.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,849 prefixes, as published 2026-10-30. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
