CZ.NIC is a Czech interest association of legal persons established by leading Internet service providers in 1998.

CZ.NIC is a member of EURid, the organization administering the European .eu domain as well as of other international companies with similar specialization (CENTR, ccNSO, etc.).

It features an open Linux based operating system with automatic updates and extra security measures.

The system central is capable to compare data from many connected Turris routers and evaluate the detected threat.

In early 2008, CZ.NIC started trial operation of the DNSSEC security technology; it was definitely launched in the .cz domain area in the fall of 2008.

In connection with this, CZ.NIC operates the project “Háčkyčárky.cz” (“acutes carons”), where Internet users can test whether their browsers and systems are compatible with the internationalized domains.

Since September 2008, the FRED registration system has been used by Angola; in 2009 it was followed by Tanzania and a year later by the Faroe Islands, Costa Rica and Estonia.

An open source routing daemon BIRD was developed at the Faculty of Mathematics and Physics, Charles University, Prague, as a school project of three students (including Ondřej Filip, the current CEO of CZ.NIC).

The routing daemon is one of the most used solutions for peering centers around the world; its abilities are utilized by the American PAIX, the Moscow MSK-IX, the Frankfurt DE-CIX, or the London LINX.

Within the .cz domain zone, mojeID is used by a large number of e-shops, news sites and even some municipalities that use the authentication system, for example, during quick surveys or polls among residents.

Main advantages of this open source solution are performance, scalability, speed and the ability to add or remove zones on the fly without server downtime.

Based on the agreement between the Czech Ministry of the Interior and CZ.NIC, from January 2011 the .cz domain administrator coordinates the national security team CSIRT.CZ.

The importance of the Internet in the Czech Republic has been gradually growing, together with the number of applications for registration of new domain names.

For example, a system of so-called special requests was established as a defense against speculators and in 2002, registration of domains without working name servers was allowed.

The decentralized domain administration system started its operation in autumn of 2003 and was immediately entered by first commercial registrars.

The registration now includes accepting the commitment to respect the decisions of the Arbitration Court, which has simplified and accelerated the dispute resolution.

In September 2008, the system was implemented by Angola, in 2009 it was followed by Tanzania and a year later by the Faroe Islands, Costa Rica and Estonia.
