1 2Options for the ipv6 module are supplied as parameters at load time. 3 4Module options may be given as command line arguments to the insmod 5or modprobe command, but are usually specified in either the 6/etc/modules.conf or /etc/modprobe.conf configuration file, or in a 7distro-specific configuration file. 8 9The available ipv6 module parameters are listed below. If a parameter 10is not specified the default value is used. 11 12The parameters are as follows: 13 14disable 15 16 Specifies whether to load the IPv6 module, but disable all 17 its functionality. This might be used when another module 18 has a dependency on the IPv6 module being loaded, but no 19 IPv6 addresses or operations are desired. 20 21 The possible values and their effects are: 22 23 0 24 IPv6 is enabled. 25 26 This is the default value. 27 28 1 29 IPv6 is disabled. 30 31 No IPv6 addresses will be added to interfaces, and 32 it will not be possible to open an IPv6 socket. 33 34 A reboot is required to enable IPv6. 35 36autoconf 37 38 Specifies whether to enable IPv6 address autoconfiguration 39 on all interfaces. This might be used when one does not wish 40 for addresses to be automatically generated from prefixes 41 received in Router Advertisements. 42 43 The possible values and their effects are: 44 45 0 46 IPv6 address autoconfiguration is disabled on all interfaces. 47 48 Only the IPv6 loopback address (::1) and link-local addresses 49 will be added to interfaces. 50 51 1 52 IPv6 address autoconfiguration is enabled on all interfaces. 53 54 This is the default value. 55 56disable_ipv6 57 58 Specifies whether to disable IPv6 on all interfaces. 59 This might be used when no IPv6 addresses are desired. 60 61 The possible values and their effects are: 62 63 0 64 IPv6 is enabled on all interfaces. 65 66 This is the default value. 67 68 1 69 IPv6 is disabled on all interfaces. 70 71 No IPv6 addresses will be added to interfaces. 72 73
