/*
 * 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_RESERVED through
 * IPPORT_USERRESERVED, 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.
 *
 * 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 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
 *
 */

/*
 * Ports < IPPORT_RESERVED are reserved for
 * privileged processes (e.g. root).         (IP_PORTRANGE_LOW)
 * Ports > IPPORT_USERRESERVED are reserved
 * for servers, not necessarily privileged.  (IP_PORTRANGE_DEFAULT)
