Unclassified APNIC
Summary
Shanghai Science and Technology Network
business china enterprise
The AS handle STN-CN is held by Shanghai Science and Technology Network Communication Limited Company.
What it's used for
- The address space is registered under the netname
STN-CNwith registrantIRT-STN-CN-CN, indicating a unified corporate estate. - The AS announces 37,888 IPv4 addresses across 56 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio suggests an internal corporate network or access provider rather than a transit hub.
Notable
- All sampled prefixes share the same registrant
IRT-STN-CN-CNand netnameSTN-CN, confirming consistent ownership. - The inventory consists of finely subdivided blocks, including multiple /21, /22, and /23 prefixes, which is characteristic of site-by-site segmentation within a large organization.
- The network has been observed in routing tables since 2001, indicating long-term operational stability.

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 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
