RIVE3-NET Masanori Sunagawa is a dormant RIPE-registered autonomous system (AS210717) in Japan with no originated prefixes, no website, no known customers, and no operational network. Public evidence is confined to RIPE WHOIS and routing intelligence platforms. The registration's import/export policy lines reference AS35661, AS20473, and AS6939, indicating possible future peering relationships. Current impact is negligible, but any BGP announcement would necessitate reassessment. Primary watchpoints include BGP activation, RPSL changes, and emergence of corporate or personal identity evidence.
The registration exists solely as a RIPE database entry with routing policy statements that reference AS35661, AS20473, and AS6939. It does not announce any IPv4 or IPv6 routes, has no active customers, and no physical infrastructure presence, making its current role that of a pre-operational or unused autonomous system holder.
The subject is tracked because any future origination of IP prefixes would introduce AS210717 into the global routing table, potentially affecting BGP path selection for networks that peer with its listed upstreams. Even in its inactive state, registry mutations or policy changes can signal organisational shifts or a move toward activation.

Currently, the ASN exerts no measurable impact on internet traffic. If the holder begins announcing prefixes, its RPSL-listed peers could see new routing relationships, and the ASN would become a factor in dependency analysis, traffic engineering, and route security monitoring. Activation could also clarify whether the entity is a legitimate business, a hobbyist, or a shell.

Several public sources
RIVE3-NET Masanori Sunagawa
RIVE3-NET Masanori Sunagawa holds autonomous system AS210717 as a RIPE NCC registration based in Japan, but originates no BGP prefixes and operates no known network, data centre, or internet exchange. This makes the entity a dormant internet number resource whose future activation could create new peering and transit dependencies for networks referenced in its routing policy statements.
Why It Matters
Currently, the ASN exerts no measurable impact on internet traffic. If the holder begins announcing prefixes, its RPSL-listed peers could see new routing relationships, and the ASN would become a factor in dependency analysis, traffic engineering, and route security monitoring. Activation could also clarify whether the entity is a legitimate business, a hobbyist, or a shell.
What Public Sources Show
RIVE3-NET Masanori Sunagawa is the public identity behind autonomous system AS210717, a RIPE-assigned number registered in Japan. The entity does not currently originate any BGP routes, making it a latent internet resource. If activated, it would introduce a new node into the global routing table, potentially creating dependencies for the networks listed in its routing policy—AS35661, AS20473, and AS6939.
Registry records from RIPE NCC show AS210717 was created on 24 September 2021 and last modified on 15 July 2025. The organisation name is Masanori Sunagawa, and the AS-name is RIVE3-NET. The registration is sponsored by ORG-VSS29-RIPE, though the sponsor’s operational role is not further explained in public sources.
Multiple routing intelligence platforms, including bgp.tools and Cloudflare Radar, confirm that AS210717 announces zero IPv4 and zero IPv6 prefixes and is absent from the global routing table. No PeeringDB entry, internet exchange presence, or data centre facilities have been indexed for the network. IPinfo lists no hosted domains, and a PeeringDB-derived page reports no exchange or facility connections.
Administrative control resides in the RIPE aut-num object for AS210717, which includes RPSL import and export lines referencing AS35661, AS20473, and AS6939. Authorised changes to the record are managed through maintainer objects, though the specific maintainer handles are not disclosed in the remote browsing interfaces used for this assessment.
No corporate website, business registration, or service description has been located for RIVE3-NET Masanori Sunagawa. The organisation object ORG-RA991-RIPE provides no further details about the entity’s structure, personnel, or commercial intent. The person named Masanori Sunagawa has no independently verifiable public profile beyond the RIPE registry.
The primary watchpoint is any future BGP announcement from AS210717, which would turn the dormant registration into an active routing entity and trigger a reassessment of its peering dependencies. Changes to the RPSL import/export fields or maintainer objects could signal a shift in ownership or operational plans.
The emergence of a corporate website, public biography, or business registration would help clarify whether the holder is an individual, a small business, or a shell.
The true purpose of the registration remains unknown. Without financial, contractual, or facility data, the nature of the registrant—whether a hobbyist, a pre-operational venture, or a shell entity—cannot be determined. Until additional public evidence surfaces, the assessment is limited to registry intelligence and the absence of routing activity.
Operating Surface
The registration exists solely as a RIPE database entry with routing policy statements that reference AS35661, AS20473, and AS6939. It does not announce any IPv4 or IPv6 routes, has no active customers, and no physical infrastructure presence, making its current role that of a pre-operational or unused autonomous system holder.
The subject is tracked because any future origination of IP prefixes would introduce AS210717 into the global routing table, potentially affecting BGP path selection for networks that peer with its listed upstreams. Even in its inactive state, registry mutations or policy changes can signal organisational shifts or a move toward activation.
Watchpoints
The registration is a latent resource that could become an operational autonomous system at any time. Its RPSL entries pre-configure potential peering relationships with three ASNs, which could introduce unexpected transit or dependency paths if activated. The absence of corporate identity raises the possibility of a shell registration, though the exact intent is unclear.
Watchpoints include: first BGP announcement from AS210717; changes to RPSL import/export lines; updates to maintainer objects; appearance of a corporate website or public biography for Masanori Sunagawa; clarification of the sponsor ORG-VSS29-RIPE's role.
No verified operator website, logo, or service description. No active prefix inventory, customer list, or facility presence. No independent person profile for Masanori Sunagawa. The full extent of the sponsor's role is not publicly explained.
