CHINANET-IDC-BJ-AP is operated by IDC, China Telecommunications Corporation.
What it's used for
- The address space carries diverse netnames including
CHINA-21VIANET,shanxun,BJTEL,CloudVsp,shinenet,Forest-Eternal,SKBJNET,ZLLX,UCLOUD-NET, andSINNET, indicating a mix of leased or historical allocations within the China Telecom estate. - With 1,884,928 IPv4 addresses announced across 606 prefixes and 16 observed neighbours, the high address-to-neighbour ratio suggests a large-scale access or hosting network rather than a transit provider.
Notable
- Registrants vary significantly from the announcer, including
IRT-CNNIC-CN,IRT-CNISP-CN,IRT-SKBJNET-CN,IRT-SINNET-CN, and unknown entities, reflecting a complex inventory of allocated blocks. - The inventory consists of 606 IPv4 prefixes and 63 IPv6 prefixes, with the largest blocks being /16s such as 42.158.0.0/16 and 114.64.0.0/16.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
