AS827

AS827 is a dormant, unrouted legacy autonomous system registered under ARIN to Alcan International Ltd., the former Canadian aluminum manufacturer later absorbed into Rio Tinto, announcing zero IPv4 and zero IPv6 prefixes as of 2026-08-07. There is no live routing infrastructure to triage.

The ASN was registered 1994-05-12 to Alcan's Kingston R&D Centre in Kingston, Ontario, Canada — a corporate/industrial research-and-development network rather than a commercial ISP, hosting, or content operator. No operator-official website, about page, or peering page exists for AS827 or Alcan International Ltd. as a distinct entity today.

Routing data corroborates the dormancy from every angle checked: CAIDA AS Rank places it at 79,459, its customer cone is a singleton (itself, 0 prefixes, 0 addresses), and its AS-relationship degree is zero across upstreams, peers, and customers. No PeeringDB network record exists (404), and RPKI status is not applicable since there are no announced prefixes to validate.

ARIN RDAP marks the registration "active," but the underlying facts read as an unmaintained legacy holding: the registrant company was absorbed into Rio Tinto in 2007, the point of contact has been flagged Unvalidated since 2011-06-17, and the autnum record has carried no update since its 1994 registration.

Operator

Alcan International Ltd. (ARIN org handle AIL-33), Kingston R&D Centre, Kingston, ON, Canada [Confirmed] — ARIN RDAP autnum/827

Country / RIR

CA, ARIN [Confirmed] — ARIN RDAP autnum/827; CAIDA ASRank asn/827 (country=CA)

Allocated

1994-05-12 (ARIN RDAP top-level autnum registration event; last-changed date is identical, no later update recorded) [Confirmed] — ARIN RDAP autnum/827

Org status

ARIN RDAP status array reads "active," but registrant company Alcan International Ltd. was absorbed into Rio Tinto in 2007, POC unvalidated since 2011-06-17, and 0 prefixes are routed — reads as a dormant/unmaintained legacy registration [Confirmed] — ARIN RDAP autnum/827; bgp.he.net/AS827

Contacts

no organization-level abuse/NOC mailbox found; the sole registered POC is an individual (ARIN handle SDA3-ARIN) and is withheld per this project's personal-contact policy; org handle AIL-33 on record with ARIN [Confirmed for handle; contact detail intentionally withheld] — ARIN RDAP autnum/827

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-07 — not in AbuseIPDB (direct check page 403), Spamhaus, Talos Intelligence, VirusTotal, or NANOG archives; dormant legacy ASN under an inactive corporate holding

Network & routing

Network type

legacy corporate/industrial R&D network (aluminum manufacturing); not a commercial ISP/hosting/content/transit network [Confirmed] — ARIN RDAP autnum/827

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat announced-prefixes/routing-status for resource 827; CAIDA ASRank asn/827

Routing/peering

NOT announced — 0 of 327 RIS peers seeing v4, 0 of 321 seeing v6; CAIDA AS degree 0 upstream / 0 peer / 0 customer; no PeeringDB network record exists for AS827 (404) [Confirmed] — RIPEstat routing-status for resource 827; CAIDA ASRank asn/827; peeringdb.com/asn/827

RPKI

not applicable — AS827 announces no prefixes, so there is no route origin to validate [Confirmed] — RIPEstat rpki-validation for resource 827

Notable usage

none documented on any operator-official source; historically an internal R&D network for Alcan (aluminum manufacturer, acquired by Rio Tinto in 2007) [Confirmed] — ARIN RDAP autnum/827; bgp.he.net/AS827

Related ASNs

none identified — no third-party source ties AS827 to a related/successor ASN [Unknown]

Analyst note

dormant/unrouted legacy ASN registered in 1994 to Alcan International Ltd., a Canadian aluminum manufacturer absorbed into Rio Tinto in 2007. All routing sources agree on zero announcements, zero peers, and a singleton customer cone; no live network to attribute activity to.
