Frequently Asked Questions

Common questions about QAS Domain Checker – WHOIS RDAP

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.

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.

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.

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.

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

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.

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.
