Hetzner Cloud offers both IPv4 (usually in a shared /26 or /27 subnet) and IPv6 (/64 subnet) connectivity to each machine. The assigned addresses can be looked up on the [https://robot.hetzner.com/server Hetzner Robot]  on the IPs tab of a machine. The public IPv4 address of the server can automatically be obtained via DHCP. For IPv6 you have to statically configure both address and gateway.
