DHCPv6 provides which type of address auto-configuration?

• A. Stateful address auto-configuration
• B. Stateless address auto-configuration
• C. Hybrid address auto-configuration
• D. No address configuration

Answer: (A)

DHCPv6 provides stateful address auto-configuration. In this mode, the DHCPv6 server assigns IPv6 addresses to clients and keeps track of which address belongs to which client, establishing and maintaining state about each binding. This is different from stateless address auto-configuration, where hosts generate their own addresses using a prefix announced by routers (Router Advertisements) and DHCPv6 is not used to assign the address. DHCPv6 can also supply other configuration data in stateless mode, but it does not supply addresses in that mode. The commonly accepted modes are stateful (addresses assigned and tracked by the server) and stateless (addresses derived by the host, with DHCPv6 providing additional information).
