Intelligent Query Protocol Selection

The system will automatically select the best query protocol: it will prioritize using the modern RDAP protocol to obtain standardized data, and for domains that do not support RDAP, it will use the traditional WHOIS protocol for querying. This ensures data accuracy while expanding the range of supported domains.
