Which two methods are commonly used by IPv6 to assign addresses to hosts?

• A. SLAAC (stateless address autoconfiguration) and DHCPv6
• B. DHCPv6 only
• C. SLAAC only
• D. Static addressing

Answer: (A)

In IPv6, hosts get addresses through two widely used methods: SLAAC (stateless address autoconfiguration) and DHCPv6. SLAAC lets a device configure its own address by using the network prefix advertised by routers (via Router Advertisements) and combining it with an interface identifier. This makes address configuration quick and doesn’t require a central server for the address itself. DHCPv6, on the other hand, involves a DHCPv6 server that can assign addresses (stateful) and/or provide other configuration information like DNS servers. Networks often use both: SLAAC for fast, automatic address generation, with DHCPv6 handling centralized management or providing necessary configuration data. The other options don’t fit as well because relying on only DHCPv6 misses the common, fast autoconfiguration path many networks use, and relying on only SLAAC misses the centralized control and extra configuration that DHCPv6 can supply. Static addressing is not practical for dynamic client networks.
