165 * Local port number conventions:
166 *
167 * When a user does a bind(2) or connect(2) with a port number of zero,
168 * a non-conflicting local port address is chosen.
169 * The default range is IPPORT_RESERVED through
170 * IPPORT_USERRESERVED, although that is settable by sysctl.
171 *
172 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
173 * default assignment range.
174 *
175 * The value IP_PORTRANGE_DEFAULT causes the default behavior.
176 *
177 * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
178 * into the "high" range. These are reserved for client outbound connections
179 * which do not want to be filtered by any firewalls.
180 *
181 * The value IP_PORTRANGE_LOW changes the range to the "low" are
182 * that is (by convention) restricted to privileged processes. This
183 * convention is based on "vouchsafe" principles only. It is only secure
184 * if you trust the remote host to restrict these ports.
185 *
186 * The default range of ports and the high range can be changed by
187 * sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
188 *
189 * Changing those values has bad security implications if you are
190 * using a a stateless firewall that is allowing packets outside of that
191 * range in order to allow transparent outgoing connections.
192 *
193 * Such a firewall configuration will generally depend on the use of these
194 * default values. If you change them, you may find your Security
195 * Administrator looking for you with a heavy object.
196 *
197 * For a slightly more orthodox text view on this:
198 *
199 * ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
200 *
201 * port numbers are divided into three ranges:
202 *
203 * 0 - 1023 Well Known Ports
204 * 1024 - 49151 Registered Ports
205 * 49152 - 65535 Dynamic and/or Private Ports
