Why each option
Unique Local Addresses (ULAs) in IPv6 are designed for private, internal network communication across subnets, but are not routable on the global Internet.
Global unicast addresses are globally routable on the Internet and are used for public communication.
Unique Local Addresses (ULAs), identified by the 'fc00::/7' prefix, are intended for communication within an organization and across multiple subnets. They are not globally routable on the Internet, similar in concept to IPv4 private addresses.
Link-local addresses (fe80::/10) are only valid and routable on a single network link (subnet) and are not routable between subnets.
Multicast addresses are used for one-to-many communication and define a group of interfaces, not a scope for inter-subnet or internet routing.
