详情介绍:

QAS Domain Checker adds a simple form to any page or post where visitors can check whether a domain is available, using RDAP — the modern, IANA-recommended replacement for the legacy WHOIS protocol. You can try it live before installing: Live demo Unlike other domain-checking plugins, this one is designed to be genuinely simple:

One single result, inline. No separate "search", "results" and "details" pages to configure — insert the block or shortcode and it just works.
Built for multilingual sites. Fully internationalized (i18n-ready) with all strings translatable. Once published, translations — including Spanish, Catalan, English, French and Portuguese — can be contributed by anyone via translate.wordpress.org, WordPress's own community translation platform. The plugin also includes an option to force a specific language for the widget regardless of the page's language.
No build tools required to maintain. The block editor script is plain JavaScript — no Node, npm or webpack pipeline involved.
Privacy-conscious. Only the domain name you search for is sent to the RDAP servers. No personal data is transmitted or stored. See "External services" below for full details.

What you get for each domain

Availability status (available / already registered)
Registrar name
Registration and expiration dates
Last changed date
Last update of the RDAP database
Name servers (DNS)
Domain status codes (e.g. transfer/update/delete lock)
DNSSEC status

How to use it Block editor: search for "Comprobador de dominio" (Domain Checker) in the block inserter, add it to any page or post, and optionally set an accent color from the block sidebar. Shortcode: add [qasdrw_domain_checker] to any page, post, or widget area that supports shortcodes. Settings Under Settings → Comprobador de dominios you can configure:

How long a result is cached before querying the RDAP server again (0 to disable caching)
Whether to force a fixed language for the widget
A list of TLDs to exclude from lookups
Whether to show a small, optional attribution link to QAS Solutions below the form (disabled by default; uses rel="nofollow" and requires explicit opt-in from the site administrator)

安装:

Upload the plugin files to /wp-content/plugins/qas-domain-rdap-whois, or install it directly from the WordPress plugin directory.
Activate the plugin through the "Plugins" screen in WordPress.
Add the block "Comprobador de dominio" from the block editor, or use the shortcode [qasdrw_domain_checker] on any page or post.
Optionally, visit Settings → Comprobador de dominios to adjust the cache duration, forced language, or excluded TLDs.

常见问题:

What is RDAP and why not classic WHOIS?

RDAP (Registration Data Access Protocol) is the modern, IANA/ICANN-recommended replacement for the legacy WHOIS protocol. It returns structured JSON instead of plain text, doesn't rely on port 43 (often blocked by hosting firewalls), and supports internationalization properly.

Which domain extensions (TLDs) are supported?

Any TLD that has a registered RDAP server according to IANA's official bootstrap registry — this covers the large majority of generic and country-code TLDs in active use. The list is fetched from IANA and cached for a week.

Does this plugin register or sell domains?

No. It only checks availability and displays public registration data. It does not connect to any registrar for purchasing and does not act as an affiliate for domain sales.

Is any personal data sent anywhere?

No personal data is transmitted. Only the domain name entered by the visitor is sent to IANA (for TLD/server lookup) and to the relevant RDAP server (for the actual query). See "External services" below.

Can I use the shortcode more than once on the same page?

Yes, [qasdrw_domain_checker] and the block can both be used multiple times on the same page or across different pages.

How do I change the widget's language regardless of the site's language?

Go to Settings → Comprobador de dominios and choose a language under "Idioma del formulario" (Form language). Leave it on the default option to always follow the page's language instead.

Does the plugin add any promotional links to my site?

Only if you explicitly enable it. There's an optional, disabled-by-default setting ("Enlace de atribución" / Attribution link) that adds a small rel="nofollow" link to QAS Solutions below the form. It is off unless you turn it on yourself, and it never affects your site's SEO.

Is there a live demo?

Yes: https://www.qasolutions.net/consulta-whois-rdap-de-un-dominio/
