The correct statements that describe characteristics of IPv6 unicast addressing are:
1. **Global addresses start with 2000::/3** - This is true. IPv6 global unicast addresses are in the range of 2000:: to 3fff:ffff:ffff:ffff:ffff:ffff:ffff:ffff.
2. **There is only one loopback address and it is ::1** - This is true. The loopback address in IPv6 is indeed ::1, which is used to represent the loopback interface.
The other statements are incorrect:
- **If a global address is assigned to an interface, that is the only allowable address for the interface** - This is not true. An interface in IPv6 can have multiple addresses of different types (global, link-local, etc.) assigned to it.
- **Link-local addresses start with FE00:/12** - This is incorrect. Link-local addresses actually start with FE80::/10.
