IPv6 GUA

1. globally unique and routable on the IPv6 internet

   • these addresses are equivalent to public IPv4 addresses

2. A GUA has 3 parts:

   • global routing prefix
     • network portion of the address that is assigned by the provider, such as an ISP, to a customer or site.
   • subnet ID
     • used by an organization to identify subnets within its site. The larger the subnet ID, the more subnets available.
   • interface ID
     • 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.
