- * 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:
- *
- * 0 - 1023 Well Known Ports
- * 1024 - 49151 Registered Ports
- * 49152 - 65535 Dynamic and/or Private Ports
