Hi,

I know I'm a bit late to ask this, but did the CentOS 7 installer kernel

(here now https://vault.centos.org/7.9.2009/os/x86_64/images/pxeboot/) ever support setting an IPv4 AND an IPv6 address on the same interface?

I've done some testing in a VM where setting EITHER IPv4 OR IPv6 works, but not both on the same interface, but is it possible to have dual stack settings applied to one interface via the kernel parameters? Assume that I have no ability to have a kickstart file locally, otherwise this could be worked around :/

You you can provide both IPv4 and IPv6 addresses. You need to provide the "ip=" option twice, once for each address you want to configure.
