Lots of examples out there to do this temporary, but can I make this secondary IP address permanent, so that it survives reboots "the fedora way", or does this really need some kind of non-standard script to make this work? While this question (*) answers this partially, there a a lot of settings in the "ifcfg" scripts these days, like UUID, AUTOCONNECT_PRIORITY and a lot of IPV_6 settings, which i do not need at this point.
So the question is really how to add a secondary ip adress properly without screwing up network settings ? I am worried that I will introduce some weird network behaviour of the machine if i just "copy" these values.
e.g. what do do with these values of the default "eth0" (copy them, change them?)
UUID=5e14c1d3-a58a-4540-8a9d-107210cc45aa AUTOCONNECT_PRIORITY=-999 IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy
