3.3.22 Dynamic DNS Function
Traditional legacy VPN system requires a static global IP address on the VPN server. In consideration of shortage of global IP addresses, SoftEther Corporation implements the "Dynamic DNS Function" on SoftEther VPN Server. Dynamic DNS is enabled by default. Dynamic DNS function notify the current global IP address of the PC to the Dynamic DNS Servers which are operated by SoftEther Corporation. A globally-unique hostname (FQDN) such as "abc.softether.net" ( "abc" varies as unique per a user) will be assigned on the VPN Server. If you tell this unique hostname to a VPN user, the user can specify it as the destination VPN Sever hostname on the VPN Client and will be able to connect the VPN Server. No IP addresses are required to know beforehand. If the IP address of the VPN Server varies, the registered IP address related to the hostname of Dynamic DNS service will be changed automatically. By this mechanism, no longer need a static global IP address which costs monthly to ISPs. You can use consumer-level inexpensive Internet connection with dynamic IP address in order to operate an enterprise-level VPN system.
