Cannot setup status IPv6 address for the specific network during installation

[shangsong]

  Try to install Ubuntu server 20.04/22.04 and setup static IPv4/IPv6 address via kernel parameters for the specific network MAC address, below solution can work for IPv4, but IPv6 will be failed with the message “ipconfig: can’t parse IP address ‘ens3f1,[2002”， please help to check if is the usage for IPv6 incorrect or provide the solution about IPv6.

Kernel parameters for IPv4(Pass): ksdevice=bootif BOOTIF=68:05:ca:44:03:87 ip=10.10.10.120::10.10.10.1:255.255.255.0::::10.10.10.1 ds=nocloud-net;s=http://XX.XX.XX.XX/

Kernel parameters for IPv6(Fail): ksdevice=bootif BOOTIF=68:05:ca:44:03:87 ip=[2002:97b:c2bb:830:10:240:210:31]:::64::eno1:none

   ip=<client-IP>:[<peer>]:<gateway-IP>:<netmask>:<client_hostname>:<interface>:{none|off|dhcp|on|any|dhcp6|auto6|ibft}[:[<mtu>][:<macaddr>]]
           explicit network configuration. If you want do define a IPv6 address, put it in
           brackets (e.g. [2001:DB8::1]). This parameter can be specified multiple times. <peer>
           is optional and is the address of the remote endpoint for pointopoint interfaces and
           it may be followed by a slash and a decimal number, encoding the network prefix
           length.

           <macaddr>
               optionally set <macaddr> on the <interface>. This cannot be used in conjunction
               with the ifname argument for the same <interface>.

(dracut is a universe package).

All I can find online seems to point that Fedora carries patches that support ipv6 addresses from the kernel command line. The only docs in the kernel itself relate to ipv4 as part of nfsroot.

Documentation/admin-guide/kernel-parameters.txt
Documentation/admin-guide/nfs/nfsroot.rst

Hi Jeff,
  Now only RHEL/Fedora can support ipv6 address via kernel parameter "ip=", SUSE use another boot parameter("hostip=") to set ipv6 address.
  My request is looking for a method to set static ipv6 address for the specified mac address during boot, like set static ipv4 address. Is it possible on Ubuntu OS? If yes, please provide the boot options on Ubuntu OSes, thanks.

[Jeff Lane  (bladernr)]

There are no plans to support this at this time. As you notied (and we discussed before in a previous call) this is from a set of Red Hat specific patches that are not upstream and available outside those kernels.
