Appendix B, TCP Port Numbers  


 

  • 0 to 1023 (Well Known Ports): The Well Known Ports are assigned by the I.A.N.A. (Internet Assigned Numbers Authority) and on most systems can only be used by system (or root) processes or by programs executed by privileged users.
    • 20 and 21 FTP;
    • 23 TELNET;
    • 25 SMTP;
    • 37 NTP;
    • 80 and 8080 HTTP;
    • 443 HTTPS.
  • 1024 to 49151 (Registered Ports): The Registered Ports are listed by the I.A.N.A. and on most systems can be used by ordinary user processes or programs executed by ordinary users (routers, specific applications...)
  • 49152 to 65535 (Dynamic and/or Private Ports) : The Dynamic and/or Private Ports are free of use.

People who want to use TCP/IP commands to synchronize databases would have to use port numbers higher than 49151.

For more information, please visit the I.A.N.A. Web site: http://www.iana.org
