AS822

AS822 is an active institutional autonomous system, registered as STJOSEPHS-AS to St. Joseph's Health Care, London and jointly operated with London Health Sciences Centre (LHSC), announcing seven IPv4 prefixes across two /16 blocks (142.89.0.0/16, 142.158.0.0/16) with zero IPv6 space, zero settlement-free peers, and no IXP presence.

ARIN RDAP records the autnum's top-level registration event as 1994-03-09, with the record last changed 2024-03-11. This is a first-party RIR registry date, not a third-party WHOIS-mirror artifact; a decoy 2024-03-08 date on the nested SJHC-4-Z org entity, and a 2025-05-30 "created" date surfaced by bgp.he.net's contact object, were both discarded in favor of the autnum's own registration event, and the date is independently corroborated by bgp.tools.

Operationally AS822 is a stub network for a hospital system (St. Joseph's Health Care London and London Health Sciences Centre, whose hospitals are academically affiliated with Western University), reaching the internet through two upstream providers — AS812 (Rogers Communications Canada) and AS819 (LARG*net, a nonprofit regional network spanning Owen Sound to Windsor) — with zero customers and zero peers. It has no PeeringDB record (a confirmed 404, not a lookup failure). CAIDA's raw data flags AS822 as cliqueMember=true, which is anomalous for a 2-provider/0-peer stub network and is reported here as a data inconsistency rather than evidence of any transit or Tier-1 role.

No RPKI ROAs were found for any of the seven announced prefixes (RPKI-unknown, not invalid), though bgp.tools reports the prefixes as IRR-registered — a weaker, more spoofable form of route-origin documentation than an RPKI ROA.

Operator

St. Joseph's Health Care, London (ARIN registrant, handle SJHC-4-Z), operated jointly with London Health Sciences Centre (LHSC) [Confirmed] — ARIN RDAP autnum/entities

Country / RIR

CA, ARIN [Confirmed] — ARIN RDAP autnum/822, CAIDA ASRank geo (London, Ontario)

Allocated

1994-03-09 (ARIN RDAP autnum top-level registration event); last changed 2024-03-11 [Confirmed] — ARIN RDAP autnum top-level events; corroborated by bgp.tools "Registration date: March 9, 1994"

Org status

active; ARIN RDAP autnum status = active, allocated 1994-03-09, last changed 2024-03-11; one ARIN POC (handle JFT10-ARIN) flagged unvalidated since 2024-04-20, which does not affect ASN status [Confirmed] — ARIN RDAP autnum/822

Contacts

ip.admins@lhsc.on.ca (organisational role mailbox, shared by the St Joseph's IP Admins and London Health Sciences Centre POC records); abuse@lhsc.on.ca (organisational abuse role mailbox). Two further ARIN POCs on this record are natural persons per their RDAP vCards, so their contact detail is correctly withheld. No single official network-operator website — the registrant entities' own sites are sjhc.london.on.ca and lhsc.on.ca (hospital corporate sites, not network-operator sites)

[Confirmed] — ARIN RDAP autnum/822 (POC vCard kind resolved per value)

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 in sources queried; NANOG mailing-list archive was CAPTCHA-gated, so absence there is uncorroborated rather than confirmed-clean

Network & routing

Network type

institutional/enterprise stub network for a hospital system, NOT an ISP or transit/peering network [Confirmed] — bgp.he.net, CAIDA ASRank asnDegree (customer=0, peer=0, provider=2)

Size

7 IPv4 prefixes / ~131,072 addresses (two /16 blocks plus their /17 halves and one /24); 0 IPv6; customer cone = 1 ASN (itself), 7 prefixes, 131,072 addresses [Confirmed] — RIPEstat announced-prefixes/routing-status, CAIDA ASRank (2026-08)

Routing/peering

2 upstream providers — AS812 (Rogers Communications Canada) and AS819 (LARG*net) — 0 peers, 0 customers; no PeeringDB record (404, confirmed absence) [Confirmed]. CAIDA raw field shows cliqueMember=true, flagged as an apparent data anomaly for a stub network [Unknown — anomaly, not asserted as fact]

RPKI

no ROAs found for any of the 7 announced prefixes (RPKI-unknown); prefixes reported IRR-registered per bgp.tools [Likely] — bgp.he.net, bgp.tools (RIPEstat rpki-validation not queried per-prefix)

Notable usage

hospital-system IT/networking for St. Joseph's Health Care London and London Health Sciences Centre (Victoria Hospital, Children's Hospital, University Hospital), academically affiliated with Western University; no evidence of any public-facing network-operator role

[Confirmed] — bgp.he.net, lhsc.on.ca

Analyst note

Encountered as an institutional hospital-network ASN with a first-party ARIN registration date of 1994-03-09; live routing runs as a pure stub behind two Canadian upstreams (Rogers, LARG*net) with no peers, no customers, and no PeeringDB presence. CAIDA's cliqueMember=true flag conflicts with its 2-provider/0-peer degree profile and is reported as a data anomaly, not a transit claim.
