Summary

Kingsoft Cloud

China · AI-generated

cloud hosting china enterprise

BJKSCNET is operated by Beijing Kingsoft Cloud Internet Technology Co., Ltd.

What it's used for

  • The address space carries cloud infrastructure, with all sampled netnames set to BJKSCNET and registrants pointing to IRT-BJKSCNET-CN or IRT-CNNIC-CN.
  • The AS announces 56,320 IPv4 addresses across 20 prefixes and 81 IPv6 prefixes, while maintaining only 12 observed neighbours, a ratio consistent with a hosting or cloud provider rather than a transit carrier.
  • Traffic from this AS consists of web and API endpoints, cloud storage services, and business workloads hosted on Kingsoft Cloud's infrastructure.

Notable

  • Registrants are consistent with the announcer, split between IRT-BJKSCNET-CN and IRT-CNNIC-CN, both associated with the Kingsoft Cloud entity.
  • Kingsoft Cloud is a subsidiary of Kingsoft Corporation, which also operates WPS Office and other software divisions.
  • The inventory is dominated by large /19 blocks in the 110.43.0.0 and 120.92.0.0 ranges, supplemented by smaller /20, /21, and /22 allocations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

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