What does SLAAC stand for in the context of IPv6 addressing?

• A. Stateless Link Address Allocation Control
• B. Simple Local Address Assignment Configuration
• C. Stateless Address Autoconfiguration
• D. Static Local Area Address Control

Answer: (C)

SLAAC stands for Stateless Address Autoconfiguration, which is a method used in IPv6 networks that allows devices to automatically configure their own IP addresses without the need for a central server or administrator intervention. This process is fundamental to IPv6's design, as it enables devices to generate unique addresses based upon the network prefix information advertised by local routers. In SLAAC, a device listens for Router Advertisement (RA) messages on the network. These messages provide information about the network prefix and other configuration settings. Using this information, the device can create its own IPv6 address by combining the network prefix with its own Interface Identifier, often derived from the device's MAC address (although privacy extensions can also modify this behavior). This mechanism simplifies network management by reducing the overhead of manual configuration or the reliance on a Dynamic Host Configuration Protocol (DHCP) server for address allocation. Additionally, because it operates in a stateless manner, SLAAC does not maintain a configuration database, which can further enhance reliability and reduce complexity in large-scale networks.
