Reference

[RFC6335]

Note

Service names and port numbers are used to distinguish between differentservices that run over transport protocols such as TCP, UDP, DCCP, andSCTP.Service names are assigned on a first-come, first-served process, asdocumented in [RFC6335].Port numbers are assigned in various ways, based on three ranges: SystemPorts (0-1023), User Ports (1024-49151), and the Dynamic and/or PrivatePorts (49152-65535); the difference uses of these ranges is described in[RFC6335]. System Ports are assigned by IETFprocess for standards-track protocols, as per [RFC6335].  User Portsare assigned by IANA using the "IETF Review" process, the "IESG Approval" process, or the "Expert Review" process, as per[RFC6335].  Dynamic Ports are not assigned.The registration procedures for service names and port numbers aredescribed in [RFC6335].Assigned ports both System and User ports SHOULD NOT be used withoutor prior to IANA registration.************************************************************************* PLEASE NOTE THE FOLLOWING:                                           **                                                                      ** 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, NOR THAT IT NECESSARILY CORRESPONDS TO THE     ** ASSIGNED SERVICE. 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.                                                   *************************************************************************
