AS923

AS923 is a small, actively routed autonomous system whose operator is not identified by any operator-published source found in an August 2026 search. As observed by the RouteViews route collector at 2026-08-20T00:00:00Z, it originates 2 IPv4 prefixes and 2 IPv6 prefixes, together estimated at 1,280 IPv4 addresses, with exactly one neighboring ASN observed in the same dump — a small, single-homed footprint, not a dormant or unrouted registration.

That single neighbor, AS26073, reflects undirected AS-path adjacency rather than a classified customer, upstream, or peer relationship. The CAIDA AS Relationships cache (dataset date 2026-08-01) carries no row for AS923 on either side, so no provider, customer, or peer can be inferred for this ASN among published neighbours; the link to AS26073 is simply unclassified, not evidence of zero real-world relationships.

Searches for an operator-published network page, peering policy, looking-glass, or a NANOG/RIPE list post under an operator's own name naming AS923 turned up nothing that qualifies. A candidate company name recurred across search results, but every occurrence traced back to third-party ASN-lookup or BGP-aggregator pages republishing registry data, not to material the party itself published; a direct connection attempt to that candidate's own domain failed at the network level, so no self-published page could be inspected either way. A NANOG post surfaced by a similar query turned out on inspection to discuss an unrelated, numerically adjacent ASN, not AS923, and was discarded.

With no operator-published source binding a name to AS923, operator, as_name, website, network_type, country, and org_status all stay Unknown. The IANA AS Number registry places AS923 in the 1-1876 range recorded as "Assigned by ARIN," so its administering RIR is ARIN; allocation date is Unknown.

Exposure

Minimal — the ASN originates only 2 IPv4 and 2 IPv6 prefixes with a single observed neighbor (AS26073), a small footprint as of the 2026-08-20 RouteViews observation.

Blocklist status

No listing found in Spamhaus SBL or ASN-DROP, AbuseIPDB, abuse.ch/URLhaus, or a community-maintained ASN blacklist (github.com/C0nw0nk/ASN-BlackList) naming AS923, as of an August 2026 search.

Community signal

No NANOG mailing-list or meeting-archive thread, Reddit networking discussion, or public outage report naming AS923 was found, as of an August 2026 search.

Hijack / leak / botnet

No public reporting of route hijacking, route leaks, or botnet/DDoS association with AS923 was found, as of an August 2026 search.

CVE / threat report

Unknown — a targeted CVE or named threat-intelligence search specific to AS923 was not completed, as of an August 2026 search.

Operator

Unknown — no operator-published source names AS923; recurring third-party mentions trace only to ASN-lookup/BGP-aggregator mirrors of registry data, not to operator-published material [Unknown]

Country / RIR

Country Unknown [Unknown]. RIR: ARIN — the IANA AS Number registry records the 1-1876 range containing AS923 as "Assigned by ARIN" [Confirmed] — the IANA Autonomous System Number registry 1-1876

Network type

Unknown [Unknown]

Size

2 IPv4 prefixes and 2 IPv6 prefixes originated; an estimated 1,280 IPv4 addresses, as observed by RouteViews on 2026-08-20 [Confirmed] — the RouteViews BGP routing data (CC BY 4.0) AS923

Routing/peering

1 distinct neighboring ASN (AS26073) observed by RouteViews on 2026-08-20 — the full observed set, not a capped sample; this is undirected AS-path adjacency, not a customer/upstream/peer classification. The CAIDA AS Relationships cache (dataset date 2026-08-01) carries no row for AS923 as either party, so 0 providers, 0 customers, and 0 peers are inferred among published neighbours — a floor, not a census. Peering policy: Unknown [Confirmed for the neighbor count and the CAIDA absence; Unknown for policy] — the RouteViews BGP routing data (CC BY 4.0) AS923, the cached registry snapshots/caida-as-rel.csv

RPKI

Unknown — an unevaluated status, not a report of an absent or invalid ROA [Unknown]

Analyst note

Small, actively routed ASN with a single observed neighbor and no CAIDA-classified relationship. No operator-published source binds a name to AS923 as of an August 2026 search; recurring third-party mentions trace only to registry-data mirrors, and a candidate operator's own domain could not be reached to check for a self-published page. RIR is ARIN, from the IANA AS Number registry range 1-1876. Allocation date, RPKI status, IX presence, and abuse contacts are Unknown as of 2026-08.
