AS841

AS841 is a dormant, legacy autonomous system registered under ARIN to Canadian Research Network (org handle CRN-6) that has announced zero IPv4 and zero IPv6 prefixes since dropping out of the global routing table around 2023-04-16, after roughly nineteen years of intermittent announcements.

The registration sits inside a single ARIN block record spanning AS838–AS842 (block name CANET2-ASN), with a registered address at a University of Toronto building rather than a standalone corporate office. RDAP status reads "Active," but that describes the registry record only — CAIDA AS Rank places it at 79,459, and its customer cone is a singleton: itself, 0 prefixes, 0 addresses.

Operator identity is where sources diverge. Third-party aggregators such as ipinfo.io and whois.ipip.net label the operator "CANARIE" — Canada's current national research-and-education network — and the canet.ca domain implied by AS841's own abuse contact is presently WHOIS-registered to CANARIE Inc. But no CANARIE-published page names AS841, CRN-6, or "Canadian Research Network," and CANARIE's live network runs under a separate ASN, AS6509, with its own PeeringDB record. This entry treats the CANARIE link as unconfirmed.

Two historical announcements are on record: 199.247.220.0/24 (first seen 2004) and 199.247.128.0/18 (last seen 2023, tagged "bogon space" by bgp.he.net). Both now overlap address ranges ARIN's current registry delegates to unrelated third parties — Hearst Connect Corporation and the Government of Yukon — most plausibly stale legacy route configuration on a now-dark ASN rather than an active hijack, though that reading is not independently adjudicated.

No registration-typed event exists in ARIN's RDAP top-level events for this block — only a last changed entry dated 2003-07-14 — verified twice and confirmed absent, unlike eight neighboring ASN records checked for comparison (AS827–AS835). AS841's only recorded BGP adjacency, historical peer AS22573 (Northwestel Inc.), was last observed before the 2023 withdrawal.

Operator

Canadian Research Network (ARIN org handle CRN-6); registered address is a University of Toronto building (255 Huron Street, Room 350, McLennan Physical Laboratories, Toronto, ON M5S 3J1) rather than a standalone corporate office [Confirmed] — ARIN RDAP autnum/entity. Part of a single ARIN block record spanning AS838–AS842 (block name CANET2-ASN); no source directly equates this registrant with a single named successor entity — third-party aggregators (ipinfo.io, whois.ipip.net) label the operator "CANARIE," but no CANARIE-published page names AS841, CRN-6, or "Canadian Research Network" [Likely/unconfirmed for the CANARIE identification].

Country / RIR

CA, ARIN [Confirmed] — ARIN RDAP; CAIDA country.iso=CA; RIPEstat abuse-contact-finder (authoritative_rir: arin).

Allocated

Unknown — no registration-typed event exists in ARIN RDAP's autnum top-level events[] for this block (AS838–AS842); only a last changed event is present (2003-07-14T15:24:03-04:00), confirmed via two independent RDAP fetches. Eight neighboring ASN records checked for comparison (AS827–AS835) do carry top-level registration events, so this looks like a genuine characteristic of this record, not a lookup gap. The last changed date is recorded separately and is NOT substituted as the allocation date

[Confirmed] — ARIN RDAP autnum.

Org status

RIR registration Active (not revoked/reclaimed) but unrouted since 2023-04-16, no live/reachable website (canet.ca times out on direct fetch), no PeeringDB record, and the ARIN POC (CA-NOC-ARIN) unvalidated since 2010-06-09 — consistent with a dormant/legacy registration. Independent corporate/legal status of "Canadian Research Network" (CRN-6) as a distinct entity is Unknown; a Corporations Canada registry search could not be executed live. canet.ca is presently WHOIS-registered to CANARIE Inc. (Canada's current national R&E network operator, whose live network runs under the separate AS6509) — a plausible but unconfirmed indicator of current stewardship

[Likely] — ARIN RDAP, bgp.he.net, who.is/whois/canet.ca.

Contacts

noc@canet.ca (ARIN POC handle CA-NOC-ARIN; vCard kind "group", fn "CA net Network Operation Center", org "Bell Global Network Operations" — a functional mailbox, not an individual); unvalidated by ARIN since 2010-06-09. Registrant address: 255 Huron Street, Room 350, McLennan Physical Laboratories, Toronto, ON M5S 3J1, Canada

[Confirmed] — ARIN RDAP, RIPEstat abuse-contact-finder.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-08 — NANOG/MARC archives return an explicit no-hits for AS841; AbuseIPDB, Talos Reputation Center, and the Spamhaus ASN lookup tool returned HTTP 403 to direct fetch (coverage gaps, not confirmed-clean results), and VirusTotal was inconclusive. Consistent with a dormant ASN out of the routing table since 2023 [Confirmed for searches performed; gaps disclosed] — marc.info/NANOG, bgp.he.net.

Network & routing

Network type

legacy/historical registration; RDAP status is "Active" but AS841 has not been visible in the global routing table since 2023-04-16 (0 IPv4/IPv6 prefixes currently announced); not a commercial ISP/transit network by any evidence found [Confirmed] — bgp.he.net/AS841, ARIN RDAP.

Size

dormant — 0 IPv4 prefixes / 0 addresses and 0 IPv6 prefixes currently announced; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; CAIDA AS rank 79,459 [Confirmed] — RIPEstat routing-status / CAIDA AS Rank / bgp.he.net (2026-08-08).

Routing/peering

NOT announced today — 0 of 327 v4 / 0 of 322 v6 RIS peers see it; CAIDA degree total 0 (customer 0, peer 0, provider 0); last visible in the global table 2023-04-12/16 after ~19 years of announcements (first seen 2004-02-13). No PeeringDB record exists for AS841 (API query returned HTTP 404). The one historically-observed BGP adjacency was AS22573 (Northwestel Inc., a Yukon/NWT/Nunavut regional carrier), last seen before the 2023 withdrawal

[Confirmed] — bgp.he.net, RIPEstat routing-status, CAIDA ASRank.

RPKI

not assessable — AS841 announces no prefixes today, so there are no ROAs to validate; bgp.he.net shows no RPKI-valid or RPKI-invalid origins. The last historically-announced prefix (199.247.128.0/18, last seen 2023-04-12) carries no ROA either way [Confirmed] — bgp.he.net, RIPEstat rpki-validation.

Notable usage

sourced null — no operator-published usage narrative was found for AS841 itself. Two historical announcements are on record (199.247.220.0/24, first seen 2004; 199.247.128.0/18, last seen 2023 and tagged "bogon space" by bgp.he.net) that now overlap address ranges ARIN's current registry delegates to unrelated third parties — Hearst Connect Corporation and the Government of Yukon — read as stale legacy route configuration, not an active hijack; not independently adjudicated [Unknown for a usage narrative; Likely for the stale-configuration reading] — bgp.he.net, RIPEstat routing-status, ARIN RDAP IP lookups.

Related ASNs

AS838, AS839, AS840, AS842 (share the same ARIN block record, CANET2-ASN, registrant CRN-6); AS22573 (Northwestel Inc., historical BGP peer, last observed before the 2023 withdrawal). AS6509 (CANARIE Inc.'s separate, currently-active ASN with its own PeeringDB record) is NOT confirmed as AS841's successor — only the canet.ca domain WHOIS ties to CANARIE Inc. [Confirmed for the block siblings and AS22573; unconfirmed/excluded for AS6509] — ARIN RDAP, bgp.he.net, peeringdb.com/asn/6509.

Analyst note

Dormant/legacy ASN inside a shared ARIN block (AS838–AS842, CANET2-ASN) registered to Canadian Research Network (CRN-6) at a University of Toronto address; unrouted since ~2023-04-16 after ~19 years of announcements. Third-party aggregators label the operator "CANARIE," but no first-party CANARIE page names AS841 or CRN-6, and CANARIE's live network runs under the separate AS6509 — this entry keeps the RDAP registrant as the confirmed operator and flags the CANARIE link as unconfirmed rather than asserting it. No registration RDAP event exists (only last changed, 2003-07-14), verified twice against eight sibling records, so allocated_date is recorded Unknown rather than substituted with the last-changed date.
