It is the way of doing for a end-user machin, in IPv6: you do not need to configure your IPv6 parameters. If an IPv6-enabled router exists in your local network, it will broadcast the needed configuration. In a sens IPv6 is more "plug and play" than IPv4. For that mecanism to work, IPv6 interfaces are always up.

Recent OSes including Fedora do configure IPv4 automatically too. You'll see 169.254.x.x addresses appear if there is no DHCP server response.

And the first step after every Fedora installation is always to disable
this microsoft feature and potential security hole.
