    PORT NUMBERS
    
(last updated 2010-07-01)

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.

DCCP Well Known ports SHOULD NOT be used without IANA registration.
The registration procedure is defined in [RFC4340], Section 19.9.

The Registered Ports are those from 1024 through 49151

DCCP Registered ports SHOULD NOT be used without IANA registration.
The registration procedure is defined in [RFC4340], Section 19.9.

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

A value of 0 in the port numbers registry below indicates that no port 
has been allocated.

* PLEASE NOTE THE FOLLOWING:                                           *
*                                                                      *
* IESG STATEMENT TO THE IANA                                           *
*    THE IESG BELIEVES THAT IANA MAY ALLOCATE AN ADDITIONAL PORT IN    *
*    THE 'USER PORT' RANGE TO PROTOCOLS WHOSE CURRENT PORT ALLOCATION  *
*    REQUIRES ACCESS TO A PRIVILEGED PORT. THIS ALLOCATION SHOULD NOT  *
*    BE AUTOMATIC, BUT MAY OCCUR UPON APPLICATION BY AN INTERESTED     *
*    PARTY WHOSE APPLICATION WOULD OTHERWISE FIT IANA'S POLICIES.      *
*                                                                      *
* 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.                                                   *
