What the respective configuration options mean

IPv4 + IPv6 connectivity

This selection gives you a static IPv4 address and a /64 IPv6 subnet, both of which are included in your server tariff. This option therefore offers you maximum compatibility and corresponds to the existing standards. If no specific selection is made when ordering, this default setting will be used automatically.

Additional IPv4 addresses and IPv6 subnets can be added as usual for an additional charge after ordering and setting up the server. A Cloud vLAN can also be added.

IPv6 Connectivity

The "IPv6 Connectivity" configuration is particularly suitable for modern applications, internal services or test environments that are already fully IPv6-capable or for servers that should only be accessible via private networks, VPNs or load balancers.

With this option, no public IPv4 address is included in the server tariff. Instead, you receive a /64 IPv6 subnet. In addition, you benefit from a monthly saving of |gross(0.50)|/ month incl. |vat|% VAT compared to the option with IPv4.

This makes the selection of IPv6 connectivity a future-oriented, scalable and cost-efficient alternative if no public IPv4 address is required.

Please note before purchasing: Additional /64 IPv6 subnets can be added at a later date for an additional charge if required. However, subsequent allocation of an IPv4 address is no longer possible.

Cloud vLAN only

This option is suitable for scenarios in which the server can be operated completely without a public network connection - for example for internal services, cluster nodes, database servers or isolated system components within a multi-level architecture. This choice can be made if all connections are made exclusively via private networks, VPNs or dedicated interconnects and no direct accessibility from the public Internet is required.

With this option, the server can only be reached via the assigned Cloud vLAN. Neither a public IPv4 nor /64 IPv6 subnet is provided.

This choice can be useful to enable a clearly demarcated, controllable network environment and thus a maximum level of isolation and security.

Important: Please note, however, that no additional IP addresses can be added at a later date if this option is selected. Your server will remain unreachable externally.
