4. Domain Name Registrar

In the next step, you want to collect the data that was provided at the time the internet domain was registered. (Note that this information need not be correct and can also be the offender's data.)

For the subsequent name resolution to work, the information must be correct for at least one, better several responsible name servers.

For data protection and organisational reasons, not each DNR lets you view all roles in an automated request process.

For instance, "RESTENA" (responsible for ".lu") allows you to request your information to be anonymised.

The "VeriSign Global Registry Services" (responsible for the very widely used ".net" and ".com" TLDs, and others) delegates the responsibility for storing specific information to the ISP .
If the internet domain is a ".net" or ".com" domain, an automated enquiry (e.g. using the "WHOIS" application in a LINUX/BSD/Unix shell or the eToolz application on a Microsoft Windows desktop) will yield information about the ISP, the name server(s) and all roles (holder, Admin-C, Tech-C and Zone-C).
The web WHOIS will only refer you to the ISP responsible (including the name server).
You need to submit a second enquiry against the ISP's WHOIS service to also obtain information about the roles:

Web-Whois (1/2)


Web-Whois (2/2)


Not every ISP offers a (non-obligatory) web WHOIS option along with the (obligatory) WHOIS service.

If the internet domain is a ".de" domain, an automated query will only provide you with the Tech-C and Zone-C roles as well as technical data (e.g. name server).
In order to obtain information about the holder and Admin-C, you need to use Denic eG's web-based WHOIS version, which requires you to enter a captcha: http://www.denic.de/domains/whois-service/web-whois.html.
(For a relevant example, please view the German sister site "domain-ermittlung.de".)

The "Public Interest Registry" (responsible for ".org") gives you access to all data it has recorded both via the WHOIS service and web WHOIS.

Here are three exemplary links to comparable web-based Whois sites:
