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. | |

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). | |

31 | We use our standard pseudo random algorithm to generate randomized |
32 | interface identifier, instead of one described in RFC 3041. | |

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 | |
38 | ||
39 | See <file:Documentation/networking/ip-sysctl.txt> for details. | |
