The SimpleLink device allows the following IPv6 global address which must consist of the prefix 2000::/3. The following acquisition methods are allowed:
- Stateless: The most significant 64 bits acquired from the RA messages (router advertisement message that is sent periodically by an IPv6 router). The least significant 64 bits are filled with a MAC address in EUI-64 format. The DAD algorithm is used to verify that the address is unique on the link. When DAD failure occurs, the global address is invalid and the device cannot communicate outside the local network.
- Stateful (DHCPv6): The IPv6 global address is learned from the DHCPv6 server. The DAD algorithm is used to verify that the address is unique on the link. When DAD failure occurs, the global address is invalid and the device cannot communicate outside the local network.
- Static: The user configures the IPv6 global address and single IPv6 DNS server address. The DAD algorithm is used to verify that the address is unique on the link. When DAD failure occurs, the global address is invalid and the device cannot communicate outside the local network.
