The author does specify both that this is not "Internet" (with capital I) and that they are not using bonjour, and that it is a proprietary technology. So it does not appear to be a mistake on the author's part. That is why the suggested solutions, where a third party http/https endpoint is needed, are not appropriate, as there would be no accessibility to those services.
According to the original asker:
"There is no Internet. we are providing chat and other services to people who dont have Internet."
and
"No, we are not using bonjour. Its a proprietary technology. We just provide chat service."
