Look up services

You can look up the information on a .eu, .ею (Cyrillic script) and .ευ (Greek script) domain name or check if it is available for registration by using the WHOIS lookup facility.

If you want to contact the holder of a particular domain name, you can get their contact details from the web-based WHOIS.

If the holder is a company or organisation, you will see the name of the company/organisation, city, country, email address, and preferred language for correspondence.

If the holder is a private person, you will only see his/her email address and preferred language for correspondence. All other personal data is hidden for privacy reasons.

For more information, please check our WHOIS policy.

If you have a reason to obtain additional contact details than those provided via the web-based WHOIS, complete the Personal Data Disclosure form and email it to [email protected] (or fax it to +32 2 401 27 51). Your request must explain why you need the holder's contact details and how you intend to use them.

Personal data disclosure is managed on the basis of the Privacy Policy.


EURid offers resolution of domain names both via IPv4 and IPv6 addresses. Domain name holders have always been able to use IPv6 addresses for their dedicated name servers, as EURid registration systems have had IPv6-capable name servers since .eu's launch in 2006.

If you are connected to the Internet via IPv6, you will automatically reach on our IPv6 address.

Name servers

Registered domain names are stored on 3 unicast name servers, located in Europe, and 3 anycast meshes located throughout the world (see the table below). EURid's name servers are updated dynamically. This means that when you register a domain name it is activated almost immediately. Any changes made to existing domain names are effective immediately as well.

YADIFA name server

YADIFA is EURid's very own open source name server implementation. We developed YADIFA to increase the robustness of the .eu name server infrastructure by adding a stable alternative to the other name server implementations we were using.

We liked YADIFA so much that we wanted to share it with you.

YADIFA was written from scratch. This means that it doesn't inherit any of the potential weaknesses present in existing software. It supports all the current protocols, including DNSSEC with NSEC and NSEC3. It's RFC compliant.

And just like other implementations, YADIFA is portable across multiple operating systems, including Linux, FreeBSD, OpenBSD and Solaris.
