About this network

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.
