How can we improve WHMCS?

Each domain lookup provider has its own advantages and limitations, which often vary depending on the TLD being searched.

The more TLDs a hosting provider offers, the more apparent these differences become.

I would propose adding an option to select a specific domain lookup provider for each TLD, rather than requiring one provider to be used globally.

Ideally, administrators could configure a default lookup provider while having the flexibility to override it for individual TLDs.

This would allow hosting providers to choose the most reliable lookup method for each extension without affecting the configuration of other TLDs.
