CZ.NIC, interest association of legal entities, was founded by leading providers of Internet services in 1998. The association currently has over 50 members. The key activities of the association include operation of the domain name registry for the .CZ domain and the 0.2.4.e164.arpa (ENUM) domain, operation of the CZ top-level domain and public education in the area of domain names.
The association is now intensively working on development of the ENUM system, extension and improvements of the domain administration system, implementation of DNSSEC and support of new technologies and projects beneficial to the Internet infrastructure in the Czech Republic. CZ.NIC is a member of the EURid association, managing the European domain – EU, and other similarly oriented organizations (CENTR, ccNSO, ITU etc.).
Since .CZ enables you to protect your business online, a domain with .CZ makes your web address unique and easy to memorize. A .CZ extension is doing much more, helping you reach and communicate with the audience in Czech Republic.
