- Privacy Extensions for Stateless Address Autoconfiguration in IPv6
- support. With this option, additional periodically-altered
- pseudo-random global-scope unicast address(es) will be assigned to
- your interface(s).
-
- We use our standard pseudo-random algorithm to generate the
- randomized interface identifier, instead of one described in RFC 3041.
-
- By default the kernel does not generate temporary addresses.
- To use temporary addresses, do
-
- echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr
-
- See <file:Documentation/networking/ip-sysctl.txt> for details.
