A Virtual Private Network (VPN) can be thought of as a private and encrypted network within a public network.
Common examples/uses include:
- Accessing a company network while away from the office
- Circumventing internet censorship
- Protecting yourself on a public Wi-Fi network such as a coffee shop or airport
These are just a few basic examples of what VPNs can be used for. Creating a VPN can be a very complicated task depending on how you would like to implement the service.
VPNs and DreamHost
DreamHost does not offer any VPN service. If you wish to create a VPN at DreamHost, the only option is to purchase a Dedicated server or DreamCompute. Since you have sudo/root access on these types of servers, you can install any VPN software you like.
Please note that this would need to be completely custom built by you. DreamHost support can not assist in any way with the configuration of your VPN.
