12. 12 Port Numbers

13. 13 Port Numbers The port numbers are divided into three ranges: 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

14. 14 Well-Known Ports The Well Known Ports are those from 0 through 1023 The Well Known Ports are controlled and assigned by the IANA and typically can only be used by system (or root) processes or by programs executed by privileged users. Ports are defined 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. To the extent possible, these same port assignments are used with the UDP [RFC768].

15. 15 Registered Ports The Registered Ports are those from 1024 through 49151 The Registered Ports are not controlled by the IANA and on most systems can be used by ordinary user processes or programs executed by ordinary users.

16. 16 Dynamic/Private Ports The Dynamic and/or Private Ports are those from 49152 through 65535
