ASSIGNMENT OF A PORT NUMBER DOES NOT IN ANY WAY IMPLY AN ENDORSEMENT OF AN APPLICATION OR PRODUCT
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
Port numbers are assigned in various ways, based on three ranges:
|49152-65535||Dynamic / Private|
User Ports are assigned by
- IANA using the “IETF Review” process
- the “IESG Approval” process
- The “Expert Review” process, as per RFC63351.
Dynamic Ports are not assigned.
Assigned ports both System and User ports SHOULD NOT be used without or prior to IANA registration.
