192 * Local port number conventions:
194 * When a user does a bind(2) or connect(2) with a port number of zero,
195 * a non-conflicting local port address is chosen.
196 * The default range is IPPORT_HIFIRSTAUTO through
197 * IPPORT_HILASTAUTO, although that is settable by sysctl.
199 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
200 * default assignment range.
202 * The value IP_PORTRANGE_DEFAULT causes the default behavior.
204 * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
205 * into the "high" range. These are reserved for client outbound connections
206 * which do not want to be filtered by any firewalls.
208 * The value IP_PORTRANGE_LOW changes the range to the "low" are
209 * that is (by convention) restricted to privileged processes. This
210 * convention is based on "vouchsafe" principles only. It is only secure
211 * if you trust the remote host to restrict these ports.
213 * The default range of ports and the high range can be changed by
214 * sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
216 * Changing those values has bad security implications if you are
217 * using a stateless firewall that is allowing packets outside of that
218 * range in order to allow transparent outgoing connections.
220 * Such a firewall configuration will generally depend on the use of these
221 * default values. If you change them, you may find your Security
222 * Administrator looking for you with a heavy object.
224 * For a slightly more orthodox text view on this:
226 * ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
228 * port numbers are divided into three ranges:
230 * 0 - 1023 Well Known Ports
231 * 1024 - 49151 Registered Ports
232 * 49152 - 65535 Dynamic and/or Private Ports
237 * Ports < IPPORT_RESERVED are reserved for
238 * privileged processes (e.g. root). (IP_PORTRANGE_LOW)
240 #define IPPORT_RESERVED 1024
243 * Default local port range, used by IP_PORTRANGE_DEFAULT
245 #define IPPORT_EPHEMERALFIRST 10000
246 #define IPPORT_EPHEMERALLAST 65535
249 * Dynamic port range, used by IP_PORTRANGE_HIGH.
251 #define IPPORT_HIFIRSTAUTO 49152
252 #define IPPORT_HILASTAUTO 65535
255 * Scanning for a free reserved port return a value below IPPORT_RESERVED,
256 * but higher than IPPORT_RESERVEDSTART. Traditionally the start value was
257 * 512, but that conflicts with some well-known-services that firewalls may
258 * have a fit if we use.
260 #define IPPORT_RESERVEDSTART 600
262 #define IPPORT_MAX 65535
265 * Definitions of bits in internet address integers.

267 * is done according to subnet mask, not the masks here.
