Domain Notes
Due to policy differences, ICP filing requirements vary depending on where the domain name is registered and where the server is located:
Domain name registered in China + server outside mainland China: no ICP filing required
Domain name registered overseas + server outside mainland China: no ICP filing required
Domain name registered in China + server in mainland China: ICP filing required
Domain name registered overseas + server in mainland China: ICP filing is required, but overseas domain names cannot be filed. Register a domain name in China in advance for the filing.
File Storage
File storage uses a third-party object storage service (OSS). Add credit in advance based on expected usage; the minimum is typically CNY 10. Complete the following configuration before use:
- Configure the OSS access domain and add a DNS record that points to the address provided by the OSS platform.
Configure the subdomain certificate on the OSS platform to enable HTTPS file access.
Configure the OSS bucket for public access.
