Which two statements describe characteristics of IPv6 unicast addressing? (Choose two.)

Question

Group of answer choices

Global addresses start with 2000::/3

If a global address is assigned to an interface, that is the only allowable address for the interface

There is only one loopback address and it is ::1

Link-local addresses start with FE00:/12

Answer 1

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.
