Hi Harald et all, The dracut man page says: ip=<client-IP>:[<server-id>]:<gateway-IP>:<netmask>:<clienthostname> :<interface>:{none|off} explicit network configuration. If you want do define a IPv6 address, put it in brackets (e.g. [2001:DB8::1]). This parame- ter can be specified multiple times. Which suggests that static ipv6 configuration is supported, but what to do with the prefix versus netmask ? ipv6 addresses do not use netmasks but instead always use the prefix notation, for example: 2001:aaaa::3/64 Regards, Hans -- To unsubscribe from this list: send the line "unsubscribe initramfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
