Softether Telecommunication Research Institute, LLC

SOFTETHER TELECOMMUNICATION RESEARCH INSTITUTE, LLC appears in ARIN registration data as a US organization (Sacramento, California) associated with the SOFTETHER-AMERICA autonomous system (AS36599). Public routing directories also show an upstream relationship to SoftEther Corporation (AS59103), indicating ties to the wider SoftEther ecosystem.

AS36599 originates 4 IPv4 prefixes and no IPv6 prefixes in commonly observed BGP views, with only one visible BGP peer (AS59103). Public IP/hostname listings and geolocation databases frequently place parts of this IP space in Japan and label some endpoints as VPN-related, while RPKI validity is shown as absent/none in multiple ASN dashboards.

There are few clear end-user reviews tied specifically to this LLC as a provider; most public commentary discusses SoftEther/VPN Gate software rather than the network operator. Abuse and blacklist aggregators show occasional reports (for example, scanning or spam signals on individual IPs), but the evidence is fragmentary and not consistent across sources.
