  11           You will still be able to do traditional IPv4 networking as well.

  28           support.  With this option, additional periodically-alter
  29           pseudo-random global-scope unicast address(es) will assigned to
  30           your interface(s).
  31
  32           We use our standard pseudo random algorithm to generate randomized
  33           interface identifier, instead of one described in RFC 3041.
  34
  35           By default, kernel do not generate temporary addresses.
  36           To use temporary addresses, do

 170           into IPv4 packets. This is useful if you want to connect two IPv6
 171           networks over an IPv4-only path.

 202           may sometimes lead to unintended routing behavior.  This can be
