Maybe the fundamental misunderstanding is that all of this is not 
alternative, but additive.

In IPv6, it is a fully normal case that a host has multiple IPv6 
addresses. In the installer, it will have a link local address, the 
address chosen in result of SLAAC, and addresses (multiple ones!) 
assigned by DHCPv6, and if we as the user for manually configured static 
addresses, those in addition. In other operating systems, other 
addresses, for example created by privacy extensions, are added as well.
