* When a user does a bind(2) or connect(2) with a port number of zero, |
* a non-conflicting local port address is chosen. |

* The default range is IPPORT_ANONMIN to IPPORT_ANONMAX, although |

* |
* The value IP_PORTRANGE_DEFAULT causes the default behavior. |
* |
* The value IP_PORTRANGE_HIGH is the same as IP_PORTRANGE_DEFAULT, |
* and exists only for FreeBSD compatibility purposes. |

* The value IP_PORTRANGE_LOW changes the range to the "low" are |
* that is (by convention) restricted to privileged processes. |
* This convention is based on "vouchsafe" principles only. |
* It is only secure if you trust the remote host to restrict these ports. |
