Summary
Trade-Van Information Services
enterprise government legacy
AS9671 (TRADEVAN-AS-AP) is held by Trade-Van Information Services Co., Ltd. (關貿網路), a Taipei-headquartered information-services company that runs Taiwan's customs-clearance and trade-facilitation value-added network. Trade-Van operates the EDI platforms through which importers, exporters, forwarders and customs brokers file with Taiwan Customs, and has expanded into adjacent e-government and e-commerce platforms.
What it's used for
This is an enterprise / service-platform network, not an access ISP. RIS sees 15 IPv4 prefixes carrying 8,192 addresses and 2 IPv6 prefixes, all of it drawn from one contiguous range: a 202.173.32.0/19 aggregate that is then deaggregated into /20s and a long tail of /24s, plus a 2405:4500::/32 with a single /48 more-specific. The deaggregation pattern is typical of a datacentre operator slicing an allocation into per-service or per-platform segments rather than of a network handing addresses out to subscribers. Only 2 observed BGP neighbours confirms the role: this network buys transit and sits at the edge, it does not sell it. The addresses sampled for reverse DNS returned no PTRs, which for a business-to-business filing platform is unremarkable.
Notable
- Trade-Van is publicly listed in Taiwan (ticker 6183) and its customs and tax-filing platforms are relied on for cross-border trade, which makes this a low-volume but high-consequence network.
- A single IPv4 /19 and one IPv6 /32 have been enough for the whole business: the inventory has stayed small and stable rather than growing with acquisitions.

Internet exchanges
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.
