softether.net Dynamic DNS Service

About the softether.net Dynamic DNS Service

The softether.net Dynamic DNS Service is a Dynamic DNS (DDNS) service. The service is provided by SoftEther Project, University of Tsukuba, Japan since March 8, 2013 for academic purpose. This service allows anyone to register a unique hostname to the "softether.net" domain with associated IPv4 and IPv6 address. This service is free of charge and is provided without warranty of any kind.

SoftEther VPN Server

he softether.net Dynamic DNS Service is designed to use with SoftEther VPN Server, an open-source free cross-platform multi-protocol VPN server. The Dynamic DNS Client is built-in in the SoftEther VPN Server service. The Dynamic DNS function assigns a world-wide unique identifier on your SoftEther VPN Server. Your global IP address of SoftEther VPN Server will follow dynamic IP address changes. If the IP address of SoftEther VPN Server suddenly changed, the IP address record which is registered to the Dynamic DNS hostname changes automatically and immediately. A VPN client user can specify the Dynamic DNS hostname as the destination VPN Server's hostname instead of the IP address. VPN Clients and VPN Bridges can keep stable connections to your SoftEther VPN Server even if the server-side Internet connection is not a static IP address contracts. For more details, please refer 1.4. Built-in Dynamic DNS (*.softether.net).
