Class A
Class B
**Class C
Class D
Class E


6. Which statement accurately describes public IP addresses?

Public addresses cannot be used within a private network.
**Public IP addresses must be unique across the entire Internet.
Public addresses can be duplicated only within a local network.
Public IP addresses are only required to be unique within the local network.
