+Subject: Adding option to randomize interface id
+
+Please find attached a patch that adds a new feature to
+wide-dhcpv6-client, namely an option ("ifid-random") in the
+prefix-interface section of dhcp6c.conf to generate a random interface
+id on startup. This is useful if you wish to have the final 64 bits of
+your IPv6 address change from time to time - a sort of very rough
+equivalent of IPv6 Privacy Extensions. If you do not add "ifid-random"
+to the config file, then nothing about the client's current behaviour
+changes.
+
+Note that if your prefix-interface section has both the current "ifid
+X" option (where X is whatever number you want to manually assign as
+your interface id) and the new "ifid-random" option, then the
+interface id is randomized and "ifid X" is ignored.
+
+Thanks,
+Christopher Martin
