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.
