187 * Local port number conventions:
188 *
189 * When a user does a bind(2) or connect(2) with a port number of zero,
190 * a non-conflicting local port address is chosen.
191 * The default range is IPPORT_RESERVED through
192 * IPPORT_USERRESERVED, although that is settable by sysctl.
193 *
194 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
195 * default assignment range.
196 *
197 * The value IP_PORTRANGE_DEFAULT causes the default behavior.
198 *
199 * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
200 * into the "high" range. These are reserved for client outbound connections
201 * which do not want to be filtered by any firewalls.
202 *
203 * The value IP_PORTRANGE_LOW changes the range to the "low" are
204 * that is (by convention) restricted to privileged processes. This
205 * convention is based on "vouchsafe" principles only. It is only secure
206 * if you trust the remote host to restrict these ports.
207 *
208 * The default range of ports and the high range can be changed by
209 * sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
210 *
211 * Changing those values has bad security implications if you are
212 * using a a stateless firewall that is allowing packets outside of that
213 * range in order to allow transparent outgoing connections.
214 *
215 * Such a firewall configuration will generally depend on the use of these
216 * default values. If you change them, you may find your Security
217 * Administrator looking for you with a heavy object.

220 *
221 * ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers

223 * port numbers are divided into three ranges:
224 *
225 * 0 - 1023 Well Known Ports
226 * 1024 - 49151 Registered Ports
227 * 49152 - 65535 Dynamic and/or Private Ports
