 * Local port number conventions:

 *

 * 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_HIFIRSTAUTO through

 * IPPORT_HILASTAUTO, although that is settable by sysctl.

 *

 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this

 * default assignment range.

 *

 * The value IP_PORTRANGE_DEFAULT causes the default behavior.

 *

 * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers

 * into the "high" range.  These are reserved for client outbound connections

 * which do not want to be filtered by any firewalls.  Note that by default

 * this is the same as IP_PORTRANGE_DEFAULT.

 *

 * 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.

 *

 * The default range of ports and the high range can be changed by

 * sysctl(3).  (net.inet.ip.port{hi,low}{first,last}_auto)

 *

 * Changing those values has bad security implications if you are

 * using a stateless firewall that is allowing packets outside of that

 * range in order to allow transparent outgoing connections.

 *

 * Such a firewall configuration will generally depend on the use of these

 * default values.  If you change them, you may find your Security

 * Administrator looking for you with a heavy object.

 *

 * For a slightly more orthodox text view on this:

 *

 *            ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers

 *

 *    port numbers are divided into three ranges:

 *

 *                0 -  1023 Well Known Ports

 *             1024 - 49151 Registered Ports

 *            49152 - 65535 Dynamic and/or Private Ports
