AS901

AS901 is a minimally routed autonomous system: RouteViews observed exactly one IPv4 prefix (a /24, 256 addresses) and zero IPv6 prefixes for this ASN on 2026-08-20, with a single neighboring ASN in the same snapshot. No source that qualifies as operator-published names AS901's holder as of an August 2026 search, so operator identity is stated as Unknown rather than inferred from third-party listings.

A candidate operator name recurs across third-party directory and autnum-mirror listings — bgpview.io, ip2location.com, and the bgp.potaroo.net autnums table — but all three republish the same underlying registry record rather than independently confirming a holder, and none is material the operator itself published. The name is withheld here rather than printed with a hedge.

The IANA AS Numbers registry places AS901 in the block "1-1876," administered by ARIN — a Confirmed RIR reading that does not depend on any assumption about the operator's headquarters. Allocation and last-updated dates are Unknown: the registration-date column is blank for this block.

The CAIDA AS Relationships cache (dataset date 2026-08-01) classifies zero provider, customer, or peer relationships touching AS901 in either direction. Its sole RouteViews-observed neighbor, AS13536, is unclassified rather than a confirmed peer. RPKI validation posture, internet-exchange presence, and any public peering policy are all Unknown for this ASN as of an August 2026 search.

Taken together, AS901 presents as a small, sparsely interconnected network with no public identity, abuse, or community footprint found as of an August 2026 search — a sourced Unknown, not a research gap.

Operator

Unknown — no operator-published source (peering policy, network/IR page, looking glass, or NANOG/RIPE list post under the operator's own name) identifies the holder of AS901 as of an August 2026 search; a candidate name recurs only across third-party directory/autnum mirrors, which do not meet the operator-provenance bar

[Unknown] — bgpview.io, ip2location.com, bgp.potaroo.net (autnums table) considered and rejected as sourcing

Country / RIR

Country Unknown [Unknown]. RIR: ARIN, per the IANA AS Numbers registry block "1-1876, Assigned by ARIN" [Confirmed] — the IANA Autonomous System Number registry

Allocated

Unknown [Unknown]

Org status

Unknown — operator identity is unconfirmed, so organizational status cannot be assessed [Unknown]

Network & routing

Network type

Unknown — no operator-published material describes this network's purpose [Unknown]

Size

1 IPv4 prefix (a /24, 256 addresses) and 0 IPv6 prefixes originated, as observed by RouteViews at 2026-08-20T00:00:00Z [Confirmed] — the RouteViews BGP routing data (CC BY 4.0) AS901

Routing/peering

1 neighboring ASN observed by RouteViews at 2026-08-20T00:00:00Z (AS13536); peer_count for this ASN is 1, the complete total, not a capped sample. The CAIDA AS Relationships cache (dataset date 2026-08-01) classifies zero provider/customer/peer relationships for AS901 in either direction — AS13536 is unclassified, not a confirmed peer

[Confirmed] — the RouteViews BGP routing data (CC BY 4.0) AS901, the cached registry snapshots/caida-as-rel.csv

RPKI

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

Notable usage

Unknown — no operator-published material found [Unknown]

Related ASNs

None identified as corporately or operationally linked. AS901's sole RouteViews-observed neighbor, AS13536, is unclassified by CAIDA and is not asserted as a relationship [Unknown] — the RouteViews BGP routing data (CC BY 4.0) AS901, the cached registry snapshots/caida-as-rel.csv

Related fields

AS rank and customer cone size are both Unknown (CAIDA AS Rank is barred under its Master AUA); IX presence and peering policy are both Unknown (PeeringDB is barred under its AUP); assignment class is Unknown — the IANA AS Numbers registry names only the block-level administering RIR (ARIN) for this range, not a per-ASN assignment class [Unknown]

Analyst note

Minimally routed ASN — one IPv4 /24, no IPv6, one unclassified neighbor, no confirmed operator, no abuse or community signal found as of an August 2026 search. RIR is ARIN by IANA block assignment; allocation date is Unknown.
