  10           This is complemental support for the IP version 6.
  11           You will still be able to do traditional IPv4 networking as well.

  13           For general information about IPv6, see
  14           <http://playground.sun.com/pub/ipng/html/ipng-main.html>.
  15           For Linux IPv6 development information, see <http://www.linux-ipv6.org>.
  16           For specific information about IPv6 under Linux, read the HOWTO at
  17           <http://www.bieringer.de/linux/IPv6/>.

  19           To compile this protocol support as a module, choose M here: the
  20           module will be called ipv6.

  22 config IPV6_PRIVACY
  23         bool "IPv6: Privacy Extensions support"
  24         depends on IPV6
  25         ---help---
  26           Privacy Extensions for Stateless Address Autoconfiguration in IPv6
  27           support.  With this option, additional periodically-alter
  28           pseudo-random global-scope unicast address(es) will assigned to
  29           your interface(s).
  30
  31           We use our standard pseudo random algorithm to generate randomized
  32           interface identifier, instead of one described in RFC 3041.
  33
  34           By default, kernel do not generate temporary addresses.
  35           To use temporary addresses, do
  36
  37                 echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr

  44         ---help---
  45           Router Preference is an optional extension to the Router
  46           Advertisement message to improve the ability of hosts
  47           to pick more appropriate router, especially when the hosts
  48           is placed in a multi-homed network.
