How the domain search works
Enter a name with or without an extension. Without an extension, we check the most popular extensions at the same time (.de, .com, .net, .org, .eu, .berlin, .at, .ch and more). With an extension, your desired domain is highlighted at the top, followed by alternatives. Domains with umlauts or other special characters (IDN) such as müller.de are converted automatically.
The lookup takes place live and directly at the responsible registry: via RDAP (the modern successor to Whois, e.g. at DENIC for .de, Verisign for .com/.net or SWITCH for .ch/.li) or via classic Whois over port 43 (e.g. nic.at for .at, EURid for .eu). For registered domains, we show all data the registry makes public: registrar, registration date, last update, expiry date, status, name servers, DNSSEC, contacts and the original text of the response.
Why can’t I see the domain holder?
Since the General Data Protection Regulation (GDPR) came into force, most registries no longer publish personal data of domain holders. For .com, .net and many new extensions, holder details are usually redacted as “REDACTED FOR PRIVACY”; the registrar often offers a contact form instead. For .de domains, DENIC only provides status and technical data via RDAP and Whois – the channels our lookup uses. What you see is always exactly what the registry or registrar makes publicly available.
How do I find out who owns a .de domain?
DENIC offers two routes: the web lookup at webwhois.denic.de shows the holder if it is a company, association or other organisation. Data of private individuals is not public; if you have a legitimate interest (e.g. an infringement of your rights), you can request the information from DENIC. Via RDAP and Whois – and therefore in our lookup – DENIC only provides status and technical data.
What is a Whois lookup?
A Whois lookup asks the responsible registry whether a domain name is registered and returns the public registration data: registrar, registration and expiry date, status and name servers. The modern successor to Whois is called RDAP; our domain search uses RDAP and, where necessary, classic Whois.
Can I check several extensions at once?
Yes. Enter the name without an extension and we check the most popular extensions such as .de, .com, .net, .org, .eu, .at and .ch at the same time. If you like, the domain search can then check all freely registrable extensions one after another.
When does a registered domain become available again?
Only when the holder cancels it or does not renew it. For .de domains, a redemption grace period of 30 days then applies, during which only the previous holder (or a third party designated by them) can register the domain again; only after that can it be registered again. For .com and other extensions, the timing depends on the expiry date and the registry’s deadlines.
Is the lookup free of charge?
Yes, the domain search is free of charge and requires no sign-up. It is intended for people using a browser: up to 10 lookups per IP address per day are possible; automated bulk queries are not permitted.
Is “available” binding?
“Available” means that the registry has no record of this name at the time of the lookup. Whether a domain can actually be registered (e.g. reserved or premium names, special rules for individual extensions) is only confirmed at registration. “Unknown” appears when a registry does not respond, limits queries or does not allow public automated lookups.
