AS858

AS858 is an active, low-visibility government ASN registered to GONET, the Government of Ontario's internal network numbering block, and it originates exactly one IPv4 prefix while relying entirely on a single upstream, AS852 (TELUS Communications Inc.), for transit.

The ASN sits inside a contiguous ARIN block, handle AS857, name GONET-ASN-17, spanning AS857–AS885, all assigned to ARIN org GOVER-10 ("GONET"), on file as the Ministry of Government Services, Infrastructure Technology Services. The block's top-level RDAP registration event dates to 1990-08-07, independently corroborated by bgp.tools; ARIN's last-changed event is 2021-02-23.

Routing telemetry (RIPEstat, CAIDA, bgp.he.net, bgp.tools) agrees AS858 announces one IPv4 prefix, 204.41.225.0/24 (256 addresses), and zero IPv6 space. CAIDA AS Rank places it at 67,700 with a singleton customer cone (1 ASN, 1 prefix, 256 addresses) and an ASN degree of provider=1 / peer=0 / customer=0 — a stub network with no visible peering or downstream customers.

No PeeringDB record exists for AS858 (direct query returned HTTP 404), and it is not named in ONIX's public Toronto IX member list. No dedicated GONET website, published peering policy, or notable public usage history was located as of an August 2026 search; these gaps are recorded as Unknown rather than inferred.

Exposure

single-homed stub AS behind one upstream (AS852/TELUS); no observed peers, no IX presence, minimal attack surface from a routing standpoint.

RPKI

no ROA found for 204.41.225.0/24 (routinator validator reports status unknown, not invalid) — stat.ripe.net rpki-validation for resource 858.

Abuse signal

none found as of a 2026-08-09 search — absent from the live Spamhaus ASN-DROP JSON feed, no NANOG mailing-list mentions, no documented BGP hijack/leak history, no AbuseIPDB/threat-intel entries.

Contact hygiene

two of three ARIN POCs are flagged unvalidated by ARIN (CSB8-ARIN since 2023-11-07; DOMAI415-ARIN since 2019-12-03); only OIA3-ARIN is currently validated.

Analyst note

AS858 is one member of a large contiguous Ontario government ASN block (AS857-885); its only observed routing relationship is transit from AS852 (TELUS). No PeeringDB entry, published peering policy, or dedicated operator website was found. Distinct from unrelated Canadian carrier ASNs (Bell Canada AS577, Bell Aliant AS855, TELUS AS852 itself) that surfaced as search noise during research — AS858 is not a carrier ASN.
