Networks
Networks provide private environments for servers to communicate directly. Every server receives a private IP address that is not on the internet. Instead, dedicated network interfaces are used to provide private layer 3 (OSI model) links between Hetzner Cloud servers. Servers can still access the internet via their public IP address.
Private network properties:
Subnets divide the Network into multiple IP ranges that can be used for different purposes. An IP range (e.g. 192.168.0.0/24) consists of the subnet address (192.168.0.0) and a subnet mask (/24). The subnet mask is needed to identify the different components of the subnet address (network-host). Any Network you create in the Cloud Console automatically comes with a default subnet.
A route sends all packets for a given destination IP prefix to the address specified in its gateway.
A vSwitch can be used to connect a Network to a dedicated server (Hetzner Robot Account).
