AS811

AS811 is a Government of Canada autonomous system registered to Shared Services Canada (SSC) that currently announces zero IPv4 and zero IPv6 prefixes — an active registration sitting in a dormant, unannounced routing state as of the check date.

SSC is a Canadian federal department, established in 2011, that provides IT infrastructure — including the "GC Backbone" and the broader GC WAN reaching roughly 4,000 domestic sites and 200 international ones — to over 140 federal organizations. AS811's network name, SSCEAST, denotes an eastern-region government network segment.

ARIN RDAP's top-level autnum registration event for AS811 is 1992-08-19 (last changed 2025-11-07), predating SSC's own 2011 creation as an agency. This is a first-party registry fact, not an error: the block was evidently inherited from a legacy federal-government predecessor registration and carried forward under SSC's current org handle (SSC-299). AS811 shares that registrant org handle (SSC-299) and CAIDA organisation ID (3d1ce0b48f) with two sibling Government of Canada ASNs, AS806 and AS810.

Routing data is unanimous across RIPEstat and CAIDA ASRank: 0 announced IPv4/IPv6 prefixes, 0 observed peers, 0 upstreams, a customer cone limited to the ASN itself (1 ASN, 0 prefixes, 0 addresses), and a CAIDA rank of 79,459. AS811 has no PeeringDB listing (peeringdb.com/asn/811 returns 404), consistent with an internal government network whose external connectivity is procured via "Enterprise Internet connectivity" rather than public peering.

RPKI validation is not applicable: with no announced prefixes there is nothing to validate a ROA against. Geolocation fields from CAIDA (longitude/latitude both 0) are unpopulated placeholders, not real coordinates, and are reported as Unknown rather than a location; the registrant address on file is Ottawa, ON.

Operator

Shared Services Canada (SSC; French: Services partagés Canada); ARIN network name SSCEAST, org handle SSC-299, Ottawa, ON [Confirmed] — ARIN RDAP autnum/entity records, canada.ca/en/shared-services

Country / RIR

CA, ARIN [Confirmed] — ARIN RDAP autnum record, RIPEstat holder data

Allocated

1992-08-19 (ARIN RDAP autnum top-level registration event); last changed 2025-11-07 [Confirmed] — ARIN RDAP autnum top-level events; note this predates SSC's 2011 founding, consistent with inheritance of a legacy federal-government block [Likely for inheritance interpretation]

Org status

active Government of Canada federal department, established 2011 under the Shared Services Canada Act and supporting Orders in Council; mandate is to provide secure digital, network, and hosting services to federal organizations

Contacts

the organisational mailbox on the SSC "Hostmaster" role record (ARIN handle HOSTM227-ARIN) is ssc.enterpriseddi-entreprise.spc@ssc-spc.gc.ca; registrant address 434 Queen Street, PO Box 9808 STN T CSC, Ottawa, ON K1G 4A8, Canada. Three further addresses returned for this resource belong to named individuals — their POC vCards declare kind: "individual" — and are withheld here

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01; Spamhaus ASN-DROP and AbuseIPDB direct lookups were blocked (404/403) and NANOG archive search was not completable (bot-verification wall), so this is best-effort rather than exhaustively verified

Network & routing

Network type

Government/enterprise WAN operator (not a commercial ISP/transit network); SSC owns and manages the GC Backbone and broader GC WAN serving 400,000+ federal users across 145+ organizations [Confirmed] — canada.ca/en/shared-services/services/connectivity

Size

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

Routing/peering

NOT announced — 0 observed peers, 0 upstreams/providers (CAIDA asnDegree total 0); no PeeringDB entry (asn/811 = 404); no public peering policy identified, consistent with government-internal connectivity procured rather than peered [Confirmed]

RPKI

not applicable — AS811 announces no prefixes, so there is no ROA to validate against [Confirmed]

Notable usage

AS811/SSCEAST is part of the Government of Canada's internal GC Backbone/GC WAN serving federal departments, not the general public; currently shows zero announced/originated prefixes, indicating internal-only use or consolidation of external announcements under a different ASN [Confirmed for zero-announcement observation; Likely for internal-only interpretation] — bgp.he.net/AS811, canada.ca/en/shared-services/services/connectivity

Related ASNs

AS806 and AS810 — both registered under the identical Shared Services Canada org handle (ARIN SSC-299) and the identical CAIDA org ID (3d1ce0b48f) [Confirmed] — rdap.arin.net/registry/entity/SSC-299, CAIDA AS Rank org data

Analyst note

Registered, actively-maintained ASN (contacts current, org record active) but not currently announced in global BGP under this number; SSC's public-facing Internet connectivity language ("Enterprise Internet connectivity") suggests traffic may transit under a different announcing ASN or purely internal routing. Registration date (1992) predates SSC's 2011 founding — a legacy-block carryover, not an anomaly.
