how to choose port

04/03/2006, 16h11

I have written a special purpose server
that I plan to put on the Internet. Is
there guidance on what ports I should
or should not use?
Thanks,
Mike.

Hi.

Port numbers, as any other Internet number, are managed by IANA
(Internet Assigned Numbers Authority).
See this link to know about port assignments:
http://www.iana.org/assignments/port-numbers

In short:
Well known ports (for root/privileged programs): 0 to 1023
Registered ports (for users programs): 1024 to 49151
Dynamic/private ports: 49152 to 65535

So, if you want to share your program, you should register a port in
the range 0-49151.
If your server is private, you can use a port in range 49152 to 65535.

Regards.
