74 * Identification of the network protocol stack
79 * Local port number conventions:
81 * Ports < IPPORT_RESERVED are reserved for privileged processes (e.g. root),
82 * unless a kernel is compiled with IPNOPRIVPORTS defined.
84 * When a user does a bind(2) or connect(2) with a port number of zero,
85 * a non-conflicting local port address is chosen.
87 * The default range is IPPORT_ANONMIX to IPPORT_ANONMAX, although
88 * that is settable by sysctl(3); net.inet.ip.anonportmin and
89 * net.inet.ip.anonportmax respectively.
91 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
92 * default assignment range.
94 * The value IP_PORTRANGE_DEFAULT causes the default behavior.
96 * The value IP_PORTRANGE_HIGH is the same as IP_PORTRANGE_DEFAULT,
97 * and exists only for FreeBSD compatibility purposes.
99 * The value IP_PORTRANGE_LOW changes the range to the "low" are
100 * that is (by convention) restricted to privileged processes.
101 * This convention is based on "vouchsafe" principles only.
102 * It is only secure if you trust the remote host to restrict these ports.
103 * The range is IPPORT_RESERVEDMIN to IPPORT_RESERVEDMAX.
