AS820

AS820 is an active, low-footprint autonomous system registered to Shared Services Canada, the Government of Canada department that provides centralized IT, network, and cyber-security services to federal institutions; it announces five IPv4 prefixes (1,280 addresses) and no IPv6 space, with a CAIDA AS Rank of 32,466 and a customer cone of just 1 ASN / 5 prefixes / 1,280 addresses.

The ASN was registered with ARIN on 1994-01-21 (last changed 2017-07-13), well before Shared Services Canada existed — third-party IRR data (bgp.he.net) historically associates it with "Industry Canada" / "ISTC-AS," consistent with a legacy federal registration later folded into SSC's mandate under the Shared Services Canada Act.

This is not a transit network or commercial ISP: CAIDA's asnDegree data shows a total degree of 1 (0 customer, 0 peer, 1 provider), and RIPEstat routing-status independently corroborates exactly one observed BGP neighbor, AS2665 — also a Shared Services Canada ASN.

That single relationship is an upstream/provider link, not a settlement-free peer, so AS820 functions as one downstream node in SSC's broader internal ASN footprint. No PeeringDB record exists for AS820 (a direct API query returns HTTP 404), so no formal peering policy is published.

RPKI coverage was tested directly against a real announced prefix, 192.197.178.0/24: RIPEstat's rpki-validation endpoint returns status "unknown" with zero covering ROAs. That is a confirmed negative — no Route Origin Authorization has been published for this AS820 origination — not an unchecked field.

No Contacts field is published for this entry, and that is deliberate. ARIN RDAP carries three individual-kind POC vCards (named staff with direct mailboxes and phone numbers) plus one group-kind Hostmaster entity; RIPEstat's abuse-contact-finder surfaces four addresses for this ASN, three of which are those individuals' personal mailboxes. Only the organizational Hostmaster address and the registrant's premises address would be publishable, and neither is included here.

Operator

Shared Services Canada (a department of the Government of Canada) [Confirmed] — ARIN RDAP (rdap.arin.net/registry/autnum/820), canada.ca/en/shared-services.html

Country / RIR

CA, ARIN [Confirmed] — ARIN RDAP autnum record

Allocated

1994-01-21 (ARIN RDAP autnum top-level registration event); last changed 2017-07-13 [Confirmed] — rdap.arin.net/registry/autnum/820

Org status

Active [Confirmed] — ARIN RDAP autnum record

Security/abuse context (NEUTRAL, DATED)

no notable public abuse or threat-feed signal found as of 2026-08-04 — not in Spamhaus's ASN-DROP dataset; live Spamhaus ASN-checker query returned HTTP 404 (consistent with unlisted); no NANOG, blocklist, or incident references found

Network & routing

Network type

Government of Canada internal enterprise/IT network operator (centralized shared-services provider for federal departments); not a commercial ISP or transit provider [Confirmed] — canada.ca/en/shared-services/corporate/mandate.html

Size

5 IPv4 prefixes announced, 1,280 addresses, 0 IPv6 prefixes; 326/327 v4 RIS collector visibility [Confirmed] — stat.ripe.net/data/routing-status/data.json?resource=AS820, api.asrank.caida.org/v2/restful/asns/820 (two independent sources agree exactly)

Routing/peering

CAIDA AS Rank 32,466; customer cone 1 ASN / 5 prefixes / 1,280 addresses; asnDegree total 1 (customer 0, peer 0, provider 1) — single neighbor AS2665 (also Shared Services Canada) is an upstream/provider relationship, not a peer; no PeeringDB network record for AS820 (API query returned HTTP 404) [Confirmed] — api.asrank.caida.org/v2/restful/asns/820, stat.ripe.net/data/routing-status/data.json?resource=AS820, peeringdb.com/api/net?asn=820

RPKI

no ROA covers the announced prefix 192.197.178.0/24 — RIPEstat rpki-validation returns status "unknown" (uncovered, not invalid); confirmed negative tested against a real announced prefix [Confirmed] — stat.ripe.net/data/rpki-validation/data.json?resource=820&prefix=192.197.178.0/24

Notable usage

historically associated with "Industry Canada" / "ISTC-AS" per third-party IRR data; now operates under Shared Services Canada's mandate to provide centralized IT, network connectivity, hosting, and cyber-security services to Government of Canada institutions under the Shared Services Canada Act [Likely for historical name; Confirmed for current mandate] — bgp.he.net/AS820, canada.ca/en/shared-services/corporate/mandate.html

Related ASNs

AS2665 (Shared Services Canada; sole observed BGP neighbor, an upstream/provider relationship per CAIDA asnDegree) [Confirmed] — api.asrank.caida.org/v2/restful/asns/820, bgp.he.net/AS820

Analyst note

this cycle resolved every previously-flagged Unknown with a live-queried value: CAIDA AS Rank (32,466), customer cone (1 ASN/5 prefixes/1,280 addresses), and RPKI (confirmed no ROA for 192.197.178.0/24). No Contacts field is published — RDAP POC and RIPEstat abuse-contact-finder data for this ASN skew to named individuals' personal mailboxes, which are deliberately withheld.
