What must your computer have to access the IPv6 Internet?

A global unicast address

List and describe the three parts of an IPv6 global unicast address:

Global Routing Prefix The global routing prefix is the prefix, or network, portion of the address that is assigned by the provider, such as an ISP, to a customer or site. Typically, RIRs assign a /48 global routing prefix to customers. This can include everyone from enterprise business networks to individual households. Subnet ID The Subnet ID is used by an organization to identify subnets within its site. The larger the subnet ID, the more subnets available. Interface ID The IPv6 Interface ID is equivalent to the host portion of an IPv4 address. The term Interface ID is used because a single host may have multiple interfaces, each having one or more IPv6 addresses. It is highly recommended that in most cases /64 subnets should be used.
