 | Options for the ipv6 module are supplied as parameters at load time. | 
 |  | 
 | Module options may be given as command line arguments to the insmod | 
 | or modprobe command, but are usually specified in either the | 
 | /etc/modules.conf or /etc/modprobe.conf configuration file, or in a | 
 | distro-specific configuration file. | 
 |  | 
 | The available ipv6 module parameters are listed below.  If a parameter | 
 | is not specified the default value is used. | 
 |  | 
 | The parameters are as follows: | 
 |  | 
 | disable | 
 |  | 
 | 	Specifies whether to load the IPv6 module, but disable all | 
 | 	its functionality.  This might be used when another module | 
 | 	has a dependency on the IPv6 module being loaded, but no | 
 | 	IPv6 addresses or operations are desired. | 
 |  | 
 | 	The possible values and their effects are: | 
 |  | 
 | 	0 | 
 | 		IPv6 is enabled. | 
 |  | 
 | 		This is the default value. | 
 |  | 
 | 	1 | 
 | 		IPv6 is disabled. | 
 |  | 
 | 		No IPv6 addresses will be added to interfaces, and | 
 | 		it will not be possible to open an IPv6 socket. | 
 |  | 
 | 		A reboot is required to enable IPv6. | 
 |  | 
 | autoconf | 
 |  | 
 | 	Specifies whether to enable IPv6 address autoconfiguration | 
 | 	on all interfaces.  This might be used when one does not wish | 
 | 	for addresses to be automatically generated from prefixes | 
 | 	received in Router Advertisements. | 
 |  | 
 | 	The possible values and their effects are: | 
 |  | 
 | 	0 | 
 | 		IPv6 address autoconfiguration is disabled on all interfaces. | 
 |  | 
 | 		Only the IPv6 loopback address (::1) and link-local addresses | 
 | 		will be added to interfaces. | 
 |  | 
 | 	1 | 
 | 		IPv6 address autoconfiguration is enabled on all interfaces. | 
 |  | 
 | 		This is the default value. | 
 |  | 
 | disable_ipv6 | 
 |  | 
 | 	Specifies whether to disable IPv6 on all interfaces. | 
 | 	This might be used when no IPv6 addresses are desired. | 
 |  | 
 | 	The possible values and their effects are: | 
 |  | 
 | 	0 | 
 | 		IPv6 is enabled on all interfaces. | 
 |  | 
 | 		This is the default value. | 
 |  | 
 | 	1 | 
 | 		IPv6 is disabled on all interfaces. | 
 |  | 
 | 		No IPv6 addresses will be added to interfaces. |
