What is the WHOIS lookup facility?

The WHOIS lookup facility is a protocol that allows users to access EURid's domain name database. Using the WHOIS lookup facility allows you to query a .eu domain name or its script variants in other scripts in order to check its availability. If a domain name is registered, the web-based WHOIS will display the contact details of the domain name holder and other additional information about the registration. Read more about the processing of personal data when using the web-based WHOIS in the WHOIS Policy and the Privacy Policy.

What is homoglyph bundling? Does EURid offer it?

Depending on the script and font used, domain names can look similar to one another. As a matter of fact, certain characters or glyphs have shapes that might look either identical or might be hard to differentiate at first glance. Domain names are considered homoglyphs of each other if all characters of one domain name are homoglyphs of all characters of the other domain names, in their respective positions.

 

A Homoglyph Bundle is a set of domain names that are all homoglyphs of each other.

 

Certain registries have adopted policies to deal with homoglyph bundles. EURid's approach is to ensure that once a domain name from a particular homoglyph bundle is registered, it is not possible to register any other domain name belonging to the same bundle.

 

This approach aims to reduce the risk of confusion created by domain names that may look similar.

Since the launch of the .eu TLD in the Cyrillic script on the 1st June 2016, the homoglyph bundling algorithm now takes legacy domain names (such as юю.eu) into account. As long as legacy Cyrillic domain names (domain names consisting of Cyrillic characters but with the Latin extension) exist, homoglyph bundling will not take the extension into account to determine if a domain name is in the same homoglyph bundle as another domain name.

 

It is worth pointing out that EURid has not allowed script mixing since the launch of IDNs, in order to reduce the risk of having confusingly similar domain names.

How do I change my contact details in the web-based WHOIS?

Please contact your registrar who will be able to change your contact details on your behalf.

 

It is very important that your contact details are correct. If your contact details are false, contain mistakes or are outdated we will not be able to contact you and you might end up losing your domain name.

 

The amount of contact information shown in the web-based WHOIS depends on whether the domain name was registered by a company or organisation or by a private person.

 

If you have registered a .eu domain name as a private person and you wish for your (personal) email address not to be visible on the web-based WHOIS, you may request that your registrar update your registration data by providing an alternative, functioning email address.

What are proxy services and why are they used?

Proxy services are offered to conceal the contact details of the domain name holder for various reasons. One of the reasons to use a proxy service would be to ensure privacy: some holders do not want their private data to be shown on the web-based WHOIS.

At EURid, we automatically minimise the amount of personal data of individuals available on the web-based WHOIS. It is limited to their email address and language, which is required in order to be able to contact the domain holder. For legal entities holding a domain name, additional information is displayed. If you have registered a .eu domain name as a private person and you wish for your (personal) email address not to be visible on the web-based WHOIS, you may request that your registrar updates your registration data by providing an alternative, functioning email address.

If you have any questions about personal data processing, please consult our WHOIS Policy and our Privacy Policy or contact us via [email protected].
