AS376

AS376 is a legacy autonomous system number registered under ARIN to Réseau d'informations scientifiques du Québec (RISQ Inc.), the non-profit research-and-education network for the province of Quebec, Canada. RISQ was founded in 1989 as a member cooperative by Quebec university leaders, and the ASN's ARIN registration date — 1989-07-27, read from the RDAP autnum object's top-level events[] — lines up with that founding year, so the allocation and the organization's origin corroborate each other rather than being coincidental. The registrant on file is RISQ Inc. at 625 René-Lévesque West, Room 300, Montreal, QC, with an abuse contact of abuse@risq.qc.ca (an ARIN POC flagged unvalidated since 2023-03-10) and technical/NOC support at support@risq.quebec. Operationally the ASN is a live provincial R&E backbone: CAIDA ranks it #1422 globally with a customer cone of 23 ASNs, and it is a clique member of the default-free zone with a total degree of 39 (22 customers, 14 peers, 3 providers). It announces on the order of a few hundred IPv4 prefixes (RIPEstat reported 202 via announced-prefixes and 278 via routing-status on 2026-07-02 — different observation windows, so treat the exact count as a moving target) plus 10 IPv6 prefixes, covering roughly 1.26 million IPv4 addresses. RISQ is present at CANIX (Montreal) and TorIX (Toronto) per PeeringDB, with facilities in Cologix MTL1/MTL3 and Telehouse Toronto; it also founded QIX, Quebec's neutral Internet exchange, in 1995 (QIX has been a legally separate not-for-profit since 2013). No notable public abuse signal was found as of 2026-07-02 — no Spamhaus or NANOG listings and only low-level background spam noise on CleanTalk — and bgp.he.net reports strong RPKI adoption (valid origins, zero invalid), consistent with a clean, well-run research network.

Analyst note

Two Quebec organizations share the "RISQ" acronym — the R&E network Réseau d'informations scientifiques du Québec (this ASN operator) vs. the unrelated Réseau d'investissement social du Québec; AS376 is confirmed the former via ARIN Org and PeeringDB. Direct fetches to risq.quebec failed on a TLS chain error, so operator-site details were recovered from search snippets and downgraded accordingly.
