Your understanding is correct. At present, the Ministry of Industry and Information Technology does not allow individuals to submit records. Only access providers can submit records. Therefore, it is impossible to set up your own record server. In addition, there are many shortcomings. For example, the company does not have such a good ventilation and operation environment as the computer room, no power protection measures, no 24-hour monitoring, and no national backbone network access environment. Companies generally do not use hardware firewalls and 24-hour duty technology. In addition, there are noise, radiation and power consumption of the server. Other issues to be considered. Generally speaking, IDC computer room is the most suitable place for servers to run. Otherwise, there would be no IDC industry. Therefore, if conditions permit, it is more cost-effective to rent or host the server.
The above is my personal opinion. I hope it helps you. If you don't understand or need help, you can come to me
