Summary

  • APNIC's aut-num record for AS63602 names CNIX and China Internet Exchange at "No.56,Building 16,JiuJingZhuang Streat,FengTai District, Beijing", country CN, maintained by MAINT-CNNIC-AP, last modified 28 November 2023.
  • RIPEstat returned announced false for that AS over a query window consisting of the single instant 2026-11-12T08:00:00Z; the prefix-overview query returned no readable payload, so its originated prefixes could not be established from that source.

What an aut-num proves

Start with the field values, because they are the only part of this story that behaves like a fact. APNIC's aut-num record for AS63602 carries as-name CNIX and two description lines: China Internet Exchange, then No.56,Building 16,JiuJingZhuang Streat,FengTai District, Beijing. Country is CN. The administrative contact is YW6487-AP, the technical contact JS3764-AP, the abuse contact AC1601-AP. The object is maintained by MAINT-CNNIC-AP and carries an incident response team named IRT-CNIX-CN. Its last modification is stamped 2023-11-28T00:58:37Z.

That is a real object in a real registry, and it is worth saying plainly what it does not establish. An aut-num records who may originate routes in a number range and who answers for them. It does not record a building full of switches, a member list, a cross-connect schedule, a licence to operate an interconnection facility, or a price. An entity can hold an AS number for years and run nothing that a stranger could plug a fibre into.

The second record narrows the picture without closing it. RIPEstat's as-overview response for AS63602 places resource 63602 inside the block 63488-63999, described as Assigned by APNIC and belonging to the IANA 16-bit Autonomous System Numbers Registry. It reports the holder as CNIX - China Internet Exchange. It reports announced: false. The query start and end times are the same value, 2026-11-12T08:00:00, and the response is stamped 2026-11-12T19:45:24.775426.

Read the shape of that measurement before reading its content. A window whose start equals its end is a photograph, not a film. Saying AS63602 announced nothing at that instant is accurate. Saying it never announces anything would be an invention, and the record cannot support it. The prefix-overview query for the same AS returned nothing readable on 12 November 2026, so the prefixes it originates could not be established from that source at all — a gap in what was retrievable, not evidence that the set is empty.

Where the word "exchange" changes hands

In most of the world BTW covers, an internet exchange is a switching fabric with a membership contract: a network buys a port, joins a peering LAN, and the exchange publishes a participant list and a traffic graph because doing so is how it sells the next port.

China's public interconnection does not run on that template. What I could read of the Ministry of Industry and Information Technology's site on 12 November 2026 described a national pilot programme of "new-type internet exchange points" in Hangzhou, Shenzhen and Zhongwei in Ningxia. Each is run by a designated operator working under ministry guidance, and the commercial terms — port access, bandwidth, tariffs — are set within that supervised framework rather than by a members' committee bidding for peers.

That material arrived as a summary of site content rather than a quoted primary document, and no tariff table, port count, participant count or traffic statistic came with it. Treat it accordingly: it establishes the administrative shape of the programme, not the terms of any particular facility. Within the retrieved set, no document named CNIX or China Internet Exchange as the operator of a designated pilot, and no document named the licence under which a network would connect to anything carrying that name.

The distinction matters commercially. At a member-governed exchange, the operating surface an outsider can check is the participant list and the published port price. At an administered exchange, the operating surface is the designation itself: which approved entity runs the facility, which class of network may buy a port, and which tariff schedule the regulator's framework permits. Neither surface is visible here.

Two records, two countries

BTW's own directory entry for CNIX China Internet Exchange files the entity under region Global, with a confidence score of 0.7, one ASN resource, no website, no separate legal jurisdiction and no recorded relationships. Its open data-gaps field asks for exactly the things a counterparty would want: the legal entity country, current services, visible assets, parent or subsidiary links and responsible public leadership contacts.

Set that beside the registry and the discrepancy is stark. APNIC says CN. The card says Global. The card is our own record, built from a single public network reference, and it is not external proof of an operating fabric; where it conflicts with the registry on a field as basic as country, the honest reading is that the card's geographic facet was never established, not that the entity operates everywhere.

This is the point at which the name becomes a liability rather than a label. A carrier evaluating a counterparty reads "China Internet Exchange" and infers a national fabric, an operator with authority, and a place to buy capacity. The record supports none of those inferences. It supports a registrant with a Beijing address and a maintainer handle that carries the CNNIC prefix — administrative parentage, not a facility description.

What a network would need to sign

Imagine the diligence file of a foreign carrier that wants a Chinese interconnection point this quarter. It needs four documents it does not have: the legal entity that would countersign, with a registration number and jurisdiction; the licence or designation that permits that entity to operate an exchange point; the eligibility rule that says whether this carrier's class of network may buy a port at all; and a tariff stated with a unit, a port size and a period.

None of the four appears in the retained record. That is not a finding that they do not exist. It is a finding that a network which treats the exchange-point label as evidence of a place it can peer has nothing here to check, and that the entity's own registered footprint — one AS number, silent at the sampled instant — gives it no independent way to test the operator's claim.

What would change the answer

Three events would move this from registration to market. A routing sample at a different instant showing AS63602 announcing prefixes would establish that the holder does more than hold. A facility participant list or tariff schedule naming the same entity would connect the registrant to a physical fabric. A ministry document naming its operator would tie the name to the designation programme.

Until one of those appears, the accurate description is narrower than the name: China Internet Exchange is a registered identity in APNIC's registry, with a Beijing address and a 2023 maintenance date, whose interconnection role is not demonstrated by anything I could retrieve. The label is doing work the record does not.
