What does SLAAC stand for?

• A. Stateless Address Autoconfiguration
• B. Stateful Address Autoconfiguration
• C. Static Address Allocation
• D. Simple Local Address Assignment

Answer: (A)

SLAAC stands for Stateless Address Autoconfiguration. In IPv6, a device can configure its own global address automatically by listening to Router Advertisements from a local router. The router provides the network prefix, and the host combines that prefix with its own interface identifier to form its address. Because there’s no central server tracking which addresses are in use, the process is stateless.

This differs from Stateful Address Autoconfiguration, where a DHCPv6 server assigns addresses and maintains state about allocations. Static Address Allocation requires manual, pre-configured addresses, not automatic. Simple Local Address Assignment isn’t a standard term for this mechanism.
