Summary

  • AS142207 has been publicly invisible in routing since 8 July 2026, per RIPEstat's view and independent observatories, but its APNIC registration objects show modifications dated after that silence began.
  • The registration remains active under WJY (Shanghai) Technology Co., Ltd. (org ORG-WTCL6-AP, LIR type), with the aut-num object last modified 14 January 2026 and IRT contact validation recorded on 4 August 2026.
  • The operator's PeeringDB profile declares 100 IPv4 and 1,000 IPv6 prefixes with 5–10 Gbps of traffic; the observed footprint at last visibility was a single /23 (151.158.14.0/23) and one /32 IPv6 prefix — a gap between self-description and measurement.
  • Third-party aggregators disagree with each other and with the registry on basic facts, from the operator's identity to street spelling, illustrating why no single data layer should be trusted alone.

The timeline the layers produce

Reassembled from the public record, AS142207's year reads like this. On 2 February 2026 at 16:00 UTC, RIPEstat's view first saw the network. The last prefix observed was 151.158.14.0/23; the last visibility stamp is 8 July 2026 at 16:00 UTC. A query window from 19 July to 2 August 2026 for announced prefixes returned empty, and a routing-status capture at 2 August 2026 08:00 UTC reported announced=false with zero visible IPv4 prefixes, zero visible IPv6 prefixes and zero observed neighbours (RIPEstat routing-status documentation, announced-prefixes documentation). Qrator Radar's connectivity window for the AS ends 6 September 2026 without new activity (Qrator Radar), and Hurricane Electric's page likewise shows last activity on 8 July 2026 (bgp.he.net).

The registry side moved later. The aut-num object for AS142207 — as-name WJY-AS-AP, country CN, org ORG-WTCL6-AP — carries a last-modified timestamp of 14 January 2026 (IPIP whois mirror). But the IRT object IRT-WJY-CN records that the registry's NOC and abuse contact mailboxes were validated on 4 August 2026, with a last-modified of 4 August 2026 13:17:26Z (an earlier snapshot variant shows 5 February 2026). A related APNIC-hostmaster maintenance object shows a modification at 26 August 2026 00:40:00Z (IPGeolocation whois dump). In other words, registry maintenance — the routine work of confirming contacts and updating objects — continued for roughly seven weeks after the network's routes stopped being observed.

What a silent routing view does and does not prove

A measurement view saying announced=false is a statement about what that view's sensors see, not about every withdrawal everywhere. BTW's earlier reporting made this distinction explicitly, and it still governs how the timeline should be read (BTW, 3 August 2026); a companion note recorded the same registry-active, routing-quiet split (BTW). The empty announced-prefixes window and zero-neighbour count are dated captures, not a global proof of withdrawal. What can be said with confidence is that multiple independent observatories — RIPEstat's reported view, Qrator Radar's window and Hurricane Electric's stamp — all converge on the same last-seen date.

The self-declared footprint versus the observed one

The operator's PeeringDB profile, last updated 25 January 2026, describes a Cable/DSL/ISP with global scope, an open peering policy, the IRR as-set AS-WJY, 5–10 Gbps of traffic, and self-declared counts of 100 IPv4 and 1,000 IPv6 prefixes (PeeringDB net 41314, org 43054). Against that, the observed footprint at last visibility was one IPv4 /23 and one IPv6 /32, with the /23 documented prefix-by-prefix at IPinfo. The profile's numbers are operator-declared and never verified by PeeringDB; the divergence here is unusually wide, and it matters because IRR as-sets and PeeringDB posture are inputs peers use when deciding whether to accept routes.

An operator web presence that names a different entity

The website PeeringDB links for the network, wjy.me, identifies the operator as WJY (Hong Kong) Limited — not the Shanghai registrant of record — and advertises LIR services, cloud services, colocation and IaaS across Hong Kong, Amsterdam, Japan and Germany, with a RIPE NCC LIR orientation (wjy.me). A RIPE-NCC-facing LIR pitch sitting alongside an APNIC-registered ASN is not itself an inconsistency, but no inspected public record connects the Hong Kong entity to the Shanghai registrant or to AS142207. BTW's directory entries for the registrant collect these layers at wjy-shanghai-technology-co-ltd and wjy-shanghai-technology-co-ltd-administrator; the word "administrator" in that slug denotes an APNIC registration role object, not a court-appointed insolvency administrator. No public insolvency or administrative notice concerning the company appears in any source inspected.

Where aggregators contradict each other

Third-party mirrors disagree on basics. iamroot.tech labels AS142207 as CERNET New Technology Co., Ltd with large IPv4 and IPv6 prefix counts (iamroot.tech) — an attribution that contradicts every APNIC object and is best read as a data error. IPinfo shows an ambiguous "Hosting" classification (IPinfo). IPGeolocation reports zero IPv4 and zero IPv6 routes (IPGeolocation), consistent with the measurement view but stark against the PeeringDB self-declaration. Even street spelling splits: PeeringDB's org record says "Jinhao Road"; the APNIC objects say "Jingao Road". None of these conflicts is individually significant; together they show how a small operator going quiet produces divergent downstream copies of its record.
