Powie’s WHOIS Domain Check

The plugin checks domain availability through the io-developer/php-whois library. Availability depends on the WHOIS service and response format used by each registry.

The settings page contains the result and reCAPTCHA options first, followed by the domain extension settings. Only active extensions are shown in the table. Activate another supported extension from the dropdown to add it to the table; deactivate an extension with its status checkbox. Set a priority for each active extension (higher values appear earlier) and select exactly one default extension. New installations start with .com active as the default; all other supported extensions are inactive until enabled. Save Changes stores the settings and table changes together.

The plugin uses the WHOIS servers and availability parsers provided by the library. It does not provide settings for custom WHOIS servers or custom availability strings.
