If for internal useage, just about any non-standard port should
suffice (unless, of course, you are trying to do standard stuff).

If you are out to build a large international app, then you might
register with iana

For my app, I selected a large unused port as my default, but allowed
the user to set their own in case of in-the-field conflicts.

The keeper of the ports:

Something that came up with Google "tcp/ip ports":
