IPv6 flags
Behavior of IPv6 hosts to IPv6 RA messages is controlled by the managed address configuration flag (M flag), and other stateful configuration flag (O flag).
M flag | O flag | Description |
---|---|---|
0 | 0 | Indicates a network without an IPv6 infrastructure. Automatic address assignment is not available. The host must use other methods, such as manual configuration. |
0 | 1 | DHCPv6 stateless. IP addresses are not assigned by DHCPv6. However, other configuration settings such as DNS, can be assigned. |
1 | 0 | Only IP addresses are assigned by DHCPv6. Typically not used. |
1 | 1 | DHCPv6 stateful. IP addresses, and other configuration settings such as DNS, are assigned via DHCPv6. |
