+ * 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.
+ *
+ * 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:
