1. How do I configure IPv6 on my network?

    IPv6 can be configured via the Data Center Designer (DCD) or Cloud API using IPv6-enabled LAN. You can get IPv6 support by configuring the network. For more information about how to enable IPv6 on Virtual Data Center LANs in DCD, see Enable IPv6.

  2. Why do we need IPv6 configuration in DCD?

    The main reason for the transition to IPv6 is the exhaustion of available IPv4 addresses due to the exponential growth of the internet and the increasing number of devices connected to it.

  3. If I use private images, do I need to adapt them in any way so that they support IONOS IPv6?

    For older versions of some images like Debian, you may need to tweak the OS initialization process of your image. For example, the Dynamic Host Configuration Protocol version 6 (DHCPv6) client may need to be run manually after the system boot. Generally, if the interfaces have not received an IPv6 address from the IONOS Dynamic Host Configuration Protocol (DHCP) server, try to run the dhcp6 client manually.

    This is because the client device may have cached the previous configuration information and needs to clear it before applying the new one. However, not all DHCPv6 implementations require a manual restart, as some may be able to automatically apply the new configuration without any intervention.
