AS837

AS837 is a live, narrow-footprint ASN registered to Shared Services Canada (SSC), the Government of Canada's IT-consolidation department, and it presently announces exactly one IPv4 prefix and no IPv6 space through a single upstream rather than operating as an independent backbone. RIPEstat, CAIDA, Hurricane Electric, and bgp.tools all agree on that single-prefix, single-upstream picture.

The prefix in question is 199.212.150.0/24 (256 addresses), routed via sole upstream AS2665 — also operated by SSC. SSC was created by the Shared Services Canada Act, which received royal assent on 2012-06-29, to centralize email, data-centre, and network services previously run separately by dozens of federal departments. ARIN RDAP registers AS837 under handle SSC-299-Z-837 with status Active.

The announced /24 sits inside a parent block first registered in 1994, well before SSC existed as an organization, suggesting a legacy departmental allocation folded into SSC's consolidated network rather than a purpose-built modern assignment.

ARIN's RDAP record for the autnum object itself carries no top-level registration event — only a last-changed timestamp of 2017-07-13. A nearby 2017-03-01 date on the same RDAP page belongs to the registrant organization entity (SSC-299-Z), not the AS837 autnum itself, so it is not treated as the allocation date here; the allocation date is recorded as unknown rather than borrowed from a different record.

CAIDA ranks AS837 deep in the global tail — AS rank 67,700 — with a customer cone limited to itself: zero downstream customers, zero visible peers, one upstream. It holds no PeeringDB network record of its own.

SSC's larger sibling ASN, AS2675, carries the operator's general-purpose traffic instead — roughly 500 IPv4 prefixes, 20-50 Gbps, and a Selective PeeringDB peering policy — and should not be confused with AS837's much smaller footprint. A secondary source, bgp.he.net, labels the announced block "Royal Canadian Mounted Police," but no primary source (ARIN, RIPEstat, CAIDA) corroborates that attribution, so it is treated as unconfirmed.

Operator

Shared Services Canada (SSC) — Government of Canada federal department consolidating IT infrastructure; ARIN handle SSC-299-Z-837; established under the Shared Services Canada Act, royal assent 2012-06-29 [Confirmed] — ARIN RDAP, laws-lois.justice.gc.ca

Country / RIR

Canada, ARIN [Confirmed] — ARIN RDAP autnum (rdap.arin.net/registry/autnum/837)

Allocated

no registration date present at the autnum's top level; last-changed 2017-07-13. A 2017-03-01 date on the same RDAP page belongs to the SSC-299-Z organization entity, not the AS837 autnum, so allocated_date is recorded null rather than borrowed from that record

[Confirmed] — ARIN RDAP autnum top-level events

Org status

active Government of Canada department; ARIN RDAP status "Active"; continues to publish current planning documents (2026-27 Departmental Plan) [Confirmed] — laws-lois.justice.gc.ca, rdap.arin.net, canada.ca departmental-plan page

Contacts

organizational abuse/technical/administrative mailbox ssc.enterpriseddi-entreprise.spc@ssc-spc.gc.ca; registered organizational address 434 Queen Street, Ottawa, ON, Canada [Confirmed] — ARIN RDAP autnum 837 entities, bgpview.io, ip2location.com. The mailbox is published because its RDAP point-of-contact record (handle HOSTM227-ARIN, fn "Hostmaster", org "Shared Services Canada", status validated) carries vCard kind: group — a function, not a person. The record lists THREE POCs in total: that group POC plus two carrying kind: individual. Every value attached to a natural person is deliberately excluded — the named individuals' own mailboxes (including three that also appear on the group POC's vCard, since kind classifies the record and not each value on it) and all three telephone numbers carried on that group vCard: two of them reappear verbatim on the individual POCs' own records, which marks those two as personal direct-dials, and the third appears only on the group record with nothing in the registry establishing it as an organizational switchboard

[Confirmed] — ARIN RDAP autnum 837 entities (vCard kind)

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found for AS837 or its /24 as of 2026-08-08 across AbuseIPDB, Spamhaus, Talos, VirusTotal, and NANOG archives (some direct checks were blocked/403, so absence isn't exhaustively confirmed everywhere); a bgp.he.net "announces bogons" label was investigated and not corroborated (prefix is IRR-valid, ordinary allocated space, visible to 326/327 RIS peers for roughly 26 years)

Network & routing

Network type

single-homed government stub network — no PeeringDB record of its own; third-party classifier ip2location tags the block "Government (GOV)" [Confirmed for the stub-network routing profile; Likely for the GOV classification] — asrank.caida.org, lite.ip2location.com/as837

Size

1 IPv4 prefix (199.212.150.0/24, 256 addresses), 0 IPv6 prefixes; CAIDA AS rank 67,700; customer cone = itself only (1 ASN / 1 prefix / 256 addresses) [Confirmed] — stat.ripe.net, bgp.he.net, bgp.tools, asrank.caida.org

Routing/peering

sole upstream AS2665 (also Shared Services Canada), 0 visible peers [Confirmed] — RIPEstat asn-neighbours, bgp.tools. No independently published peering policy for AS837 itself; sibling AS2675 (not AS837) declares a "Selective" PeeringDB policy with IX presence at CANIX Montreal, TorIX, and VANIX [Likely, re: AS837 lacking an independent policy] — peeringdb.com/net/20183

RPKI

not covered — no ROA validates the sole announced prefix [Confirmed] — stat.ripe.net/data/rpki-validation

Notable usage

registered to Shared Services Canada; the announced /24 sits inside a parent block first RDAP-registered 1994-03-23, predating SSC's 2012 formation, consistent with a legacy departmental block folded into SSC's network. bgp.he.net's page separately names the block "Royal Canadian Mounted Police" — a single uncorroborated secondary source [Likely for the legacy-block inference; Unknown for the RCMP attribution] — rdap.arin.net, bgp.he.net

Related ASNs

AS2665 (sole upstream, also SSC) [Confirmed]; AS2675 (sibling SSC ASN, ~500 IPv4 prefixes, 20-50 Gbps, Selective PeeringDB policy) [Confirmed] — stat.ripe.net/asn-neighbours, peeringdb.com/net/20183

Analyst note

AS837 is a small, single-/24 government stub ASN riding sibling ASN AS2665 as its sole upstream, not a general-purpose backbone (that role sits with AS2675). No autnum-level RDAP registration date exists, so allocated_date is null rather than substituted from the organization entity's date. The bgp.he.net "Royal Canadian Mounted Police" and "announces bogons" labels were both investigated and neither is corroborated by a primary source.
