Port Numbers




ORT NUMBERS





(last updated 19 January 2005)





The port numbers are divided into three ranges: the Well Known Ports,



the Registered Ports, and the Dynamic and/or Private Ports.





The Well Known Ports are those from 0 through 1023.





The Registered Ports are those from 1024 through 49151





The Dynamic and/or Private Ports are those from 49152 through 65535







************************************************************************



* PLEASE NOTE THE FOLLOWING: *



* *



* 1. UNASSIGNED PORT NUMBERS SHOULD NOT BE USED. THE IANA WILL ASSIGN *



* THE NUMBER FOR THE PORT AFTER YOUR APPLICATION HAS BEEN APPROVED. *



* *



* 2. ASSIGNMENT OF A PORT NUMBER DOES NOT IN ANY WAY IMPLY AN *



* ENDORSEMENT OF AN APPLICATION OR PRODUCT, AND THE FACT THAT NETWORK *



* TRAFFIC IS FLOWING TO OR FROM A REGISTERED PORT DOES NOT MEAN THAT *



* IT IS "GOOD" TRAFFIC. FIREWALL AND SYSTEM ADMINISTRATORS SHOULD *



* CHOOSE HOW TO CONFIGURE THEIR SYSTEMS BASED ON THEIR KNOWLEDGE OF *



* THE TRAFFIC IN QUESTION, NOT WHETHER THERE IS A PORT NUMBER *



* REGISTERED OR NOT. *



************************************************************************







WELL KNOWN PORT NUMBERS





The Well Known Ports are assigned by the IANA and on most systems can



only be used by system (or root) processes or by programs executed by



privileged users.





Ports are used in the TCP [RFC793] to name the ends of logical



connections which carry long term conversations. For the purpose of



providing services to unknown callers, a service contact port is



defined. This list specifies the port used by the server process as



its contact port. The contact port is sometimes called the



"well-known port".





To the extent possible, these same port assignments are used with the



UDP [RFC768].





The range for assigned ports managed by the IANA is 0-1023.
