Which method of IPv6 prefix assignment uses the prefix from RA messages?

• A. DHCPv6
• B. Manual assignment
• C. SLAAC
• D. Static configuration

Answer: (C)

The method of IPv6 prefix assignment that uses the prefix from Router Advertisement (RA) messages is Stateless Address Autoconfiguration (SLAAC). In the context of IPv6, SLAAC allows devices on the network to automatically configure their own IP addresses without the need for a DHCP server. When a device receives an RA message from a router, it extracts the prefix information included in that message. This prefix, along with its interface identifier (generated either randomly or based on the device's MAC address), forms the complete IPv6 address. SLAAC facilitates ease of configuration in large networks, as devices can autonomously create their own addresses and do not require static assignments or manual configurations. This method is particularly beneficial in environments where mobility and dynamic changes in devices occur frequently, as it simplifies network administration while ensuring proper address assignments.
