SLAAC is a method in which a device can obtain an IPv6 global unicast address without the services of a DHCPv6 server.
Dynamic Host Configuration Protocol for IPv6 (Stateful DHCPv6)
Stateful DHCPv6 is similar to DHCPv4. In this case, the RA message informs the client not to use the information in the RA message.
Router Advertisement (RA) message
RA messages are sent by routers to provide addressing information to clients configured to obtain their IPv6 addresses automatically. The RA message includes the prefix and prefix length of the local segment.
stateless DHCPv6 Option (Router Advertisement and DHCPv6)
The stateless DHCPv6 option informs the client to use the information in the RA message for addressing, but additional configuration parameters are available from a DHCPv6 server.
Stateful DHCPv6 (DHCPv6 only)
This option is the most similar to DHCPv4. In this case, the RA message informs the client not to use the information in the RA message.
Stateless DHCPv6 client
The client sends a DHCPv6 INFORMATION-REQUEST message to the DHCPv6 server requesting only configuration parameters, such as DNS server address.
Stateful DHCPv6 client
The client sends a DHCPv6 REQUEST message to the server to obtain an IPv6 address and all other configuration parameters from the server.
