I know there is a parameter named
ip which lets you configure IPv4 addresses on the Linux kernel through the boot loader. That looks like the following:
I'm looking for an equal parameter for IPv6 configuration. I couldn't find anything about this in the kernel documentations.
Update: Because of a lot of you asked why I would need this: The idea to use a kernel configuration came up related to this problem. I suspect the regular boot-up interface configuration is not done, because the interfaces are already up. The reason for this could be that I'm using a pre-boot environment with a Dropbear SSH server to allow me to unlock my encrypted root partition. The IP addresses for this environment are configured through GRUB with the
ip= parameter. There is no DHCP or Router Advertisement available on that Ethernet segment and as this is the uplink segment provided by a large hosting company, there is no way to change that fact.
