AS920

AS920 is a currently dormant autonomous system: the RouteViews route collector recorded zero originated IPv4 prefixes and zero IPv6 prefixes for it at the 2026-08-20 snapshot, and no permitted source identifies who operates it.

That zero-prefix reading is a single collector's instant, not a certification that the ASN has never routed or never will; a dormant snapshot at one dump time does not rule out routing seen elsewhere or at another time. No neighboring ASNs were observed alongside it in that same snapshot.

The CAIDA AS Relationships cache (dataset date 2026-08-01) carries no row naming AS920 in either its provider/customer column, so no upstream, customer, or peer relationship is classified for this ASN. That is an absence from the cache, not a confirmed zero — a pair CAIDA has not classified is unclassified, never a network fact about the ASN's peering.

The IANA AS Number registry places AS920 in the 1-1876 range recorded as "Assigned by ARIN," so its administering RIR is ARIN. The registry supplies no finer-grained assignment class, allocation date, or last-updated timestamp for this individual ASN, and none is available from any permitted source, so both stay Unknown.

A targeted search for operator-published material naming AS920 — peering policy pages, looking-glass listings, NANOG/RIPE mailing-list posts under an operator's own name, and general operator-facing references — returned no result that names AS920 as anyone's own ASN as of an August 2026 search. Every hit was unrelated networking-adjacent noise. Operator identity, country, network type, and notable usage therefore stay Unknown rather than a guessed or mirror-sourced name.

Abuse signal

No entry naming AS920 was found in AbuseIPDB, Spamhaus (SBL/XBL/DROP), or Abusix as of an August 2026 search; this is a sourced null result, not a confirmed clean record — abuseipdb.com, spamhaus.org.

Community discussion

No NANOG mailing-list thread or Reddit networking-community post referencing AS920 was located as of an August 2026 search — archive.nanog.org, seclists.org/nanog.

CVE / malware

No CVE, malware, or botnet command-and-control association naming AS920 found as of an August 2026 search.

Routing exposure

With zero prefixes observed at the 2026-08-20 RouteViews snapshot, AS920 currently presents no announced address space to probe; this reflects one collector's instant, not a guarantee of permanent dormancy.

Operator

Unknown — no operator-published material (peering policy page, looking-glass listing, NANOG/RIPE post under an operator's own name) identifies the holder of AS920 as of an August 2026 search [Unknown]

Country / RIR

Country Unknown — no permitted source names the operator's location. RIR: ARIN — the IANA AS Number registry records the 1-1876 range containing AS920 as "Assigned by ARIN" [Confirmed for RIR; Unknown for country] — the IANA Autonomous System Number registry 1-1876

Allocated

Unknown [Unknown]

Org status

Unknown — no permitted source identifies the registrant organization or its operating status [Unknown]

Contacts

Network & routing

Network type

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

Size

0 IPv4 prefixes and 0 IPv6 prefixes originated, as observed by RouteViews at the 2026-08-20 dump [Confirmed] — the RouteViews BGP routing data (CC BY 4.0) AS920

Routing/peering

0 neighboring ASNs observed by RouteViews at the 2026-08-20 dump. The CAIDA AS Relationships cache (dataset date 2026-08-01, CAIDA Public AUA) carries no row naming AS920 in either column, so no provider, customer, or peer relationship is classified — unclassified, not zero as a network fact. Peering policy: Unknown [Confirmed for the RouteViews figure; Unclassified for CAIDA relationships; Unknown for policy] — the RouteViews BGP routing data (CC BY 4.0) AS920, the cached registry snapshots/caida-as-rel.csv AS920

RPKI

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

Notable usage

Unknown — no operator-published material identifies any deployment [Unknown]

Related ASNs

None found [Unknown]

Related fields

AS rank, customer cone size, IX presence, and MANRS membership are all Unknown [Unknown]

Analyst note

AS920 shows zero originated prefixes and zero observed neighbors at the RouteViews 2026-08-20 snapshot — a single-collector instant, not proof of permanent dormancy. The CAIDA AS Relationships cache (dataset date 2026-08-01) has no row for AS920 in either column, so relationship roles are unclassified rather than confirmed absent. RIR is ARIN, from the IANA AS Number registry range 1-1876. A structured operator-identity search across peering-policy, looking-glass, and mailing-list surfaces returned no operator-published material naming AS920, so operator, country, network type, org status, and notable usage all stay Unknown. No abuse-feed, community-discussion, or CVE signal was found as of an August 2026 search.
