FAQ on extended network configuration
It is not possible to subsequently change the selected network configuration as in the ordering process - regardless of the configuration - for server products that have already been set up.
However, with the "IPv4 + IPv6 Connectivity" option, you can book additional IPv4 addresses or /64 IPv6 subnets for an additional charge after setup. With the "IPv6 Connectivity" option, you can add additional /64 IPv6 subnets. You can find out more here in the Help Center.
- IPv4 + IPv6 connectivity: Yes. Additional public IPv4 addresses and /64 IPv6 subnet can be added at any time for a fee. IPv4 address from €2.00/month, /64 IPv6 subnet from €1.00/month. You can find out more about purchasing additional IP addresses in the Help Center.
- IPv6 connectivity: Only additional /64 IPv6 subnets can be added. An IPv4 address cannot be added retrospectively.
- Cloud vLAN Only: No extension to public IP addresses possible. The server remains permanently accessible only via the private Cloud vLAN.
IPv4 addresses are very limited worldwide and are becoming increasingly complex and expensive to procure. For this reason, server tariffs with an included IPv4 address will be more expensive in the future than those that only require /64 IPv6 subnets.
No. If "Cloud vLAN only" is selected, it is not possible to add public IP addresses at a later date. The server remains permanently accessible exclusively via the private Cloud vLAN. In this case, please order a new tariff with the appropriate configuration.
If you do not know exactly which configuration is suitable for your project, we recommend the standard setting "IPv4 + IPv6 Connectivity" with a public IPv4 address and a /64 IPv6 subnet. It offers the highest compatibility and is suitable for almost all application scenarios.
The extended network options are currently only available for new orders of our root servers from generation 12. In the future, we will gradually roll out these options to other product categories.
No. Servers that have already been set up are not affected by this change.
If you purchased your Root Server before 16.12.2025, it is not possible to upgrade to the tariffs with "IPv6 Connectivity" or "Cloud vLAN only". However, you can still upgrade to larger Root Server tariffs within the same generation and in this case you will still have an IPv4 address and a /64 IPv6 subnet included. Please note the general guidelines for upgrades.
