ccTLD will treat personal and corporate data differently.
A common interpretation of The General Data Protection Regulation (GDPR) is that it applies to individuals who live in Europe but not businesses there. Still, most models I’ve seen for Whois compliance post-GDPR treat all types of registrants the same.
Austria’s .at top level domain is taking a different approach. As a result of GDPR, it will obfuscate natural person’s information, but not company info. According to the group:
In future the data shown for domains owned by natural persons will only include the domain name, the registrar responsible and necessary technical information. If a company or organisation owns the domain, the holder’s name and address will still be published, although contact data like e-mail address, telephone and fax number can be hidden upon request. The registrar submits information on whether a domain is held by a natural or legal person when registering the domain. If a private individual requests that their data be displayed, the registrar can also arrange this. “There will certainly be a lot of cases where people will definitely want to show that a real, trustworthy person is responsible for a particular website,” explains [head of nic.at’s legal department Barbara] Schlossbauer.
For example, I register my domains under a company name, so my Whois records would remain public.
