About this network

The network of the SoftEther Telecommunication Research Institute, LLC, the entity behind the SoftEther VPN software and the academic VPN Gate project. The org is a US-registered ARIN LLC (Sacramento, California), but the project originates from Japan and its IPs egress from Tokyo.

What it's used for

• VPN egress for SoftEther / VPN Gate users. VPN Gate is a volunteer-run public relay experiment (from the University of Tsukuba) that lets people bypass censorship by routing through donated relay servers.

Notable

• An IP here is a VPN exit, not an end user's real address. VPN Gate relays are public and heavily shared, so these IPs appear prominently on VPN/proxy detection and blocklists.

Interesting

• SoftEther began as a University of Tsukuba research project by Daiyuu Nobori and remains widely used open-source multi-protocol VPN software.
