WESTONE is operated by China Electronics Technology Cyber Security Co.,LTD.

What it's used for

  • The address space carries corporate infrastructure, identified by the netname WESTONE and registrant IRT-WESTONE-CN for both announced prefixes.
  • The AS announces 2048 IPv4 addresses across 2 prefixes (103.203.216.0/22 and 202.61.88.0/22) with 3 observed neighbours, indicating a small-scale internal or business network rather than a transit provider.
  • Traffic from this AS consists of web and API endpoints associated with the company's cybersecurity operations, as the organization specializes in cyber security solutions.

Notable

  • Registrants for both prefixes are consistent with the announcer, listing WESTONE as the netname and IRT-WESTONE-CN as the registrant.
  • The address inventory is compact, consisting of two /22 blocks, which aligns with the profile of a specialized corporate entity rather than a large-scale ISP.

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.
