Which IPv6 address type is routable on the Internet?

Explanation:
Global Unicast addresses are the IPv6 addresses intended for Internet-wide routing. They are publicly routable and globally unique, typically drawn from the 2000::/3 space, so devices with these addresses can be reached across the Internet whenever proper routes exist. In contrast, Link-Local addresses (FE80::/10) exist only on a single link and are used for local communication, such as neighbor discovery and automatic configuration; routers do not forward them. The Loopback address (::1) is reserved for testing and communication within the same host and isn’t routable to other devices. Unique Local addresses (FC00::/7) are meant for private use within an organization and are not intended to be reachable on the public Internet, though they can be routed inside private networks. So, the address type that is designed to be routable on the Internet is the Global Unicast type.
