Do you want to make sure that your domain is not targeted by intruders and bogus sites? Do you want your users to provide the best security? Do you know which sector has the greatest success in safety? See what the Czech region is and what is DNSSEC.

DNSSEC and popularity of the Czech sector

The Internet is a great thing that is so widespread and desirable and is used by so many people around the world and there are so many computers and other devices that are connected that security is in danger and still need to work on it. The Internet is a common object of attacks that are then personally abused and other data from other users in order to enrich or degrade information and the like.

That is why we must feel great pride that our Czech territory belongs to those in the world who are known for their quality of security and their high trust. The Czech sector is also one of the first to start using DNSSEC security since 2008.


The Czech domain administrator is CZ.NIC, which also strengthens DNSSEC security.

And what exactly does DNSSEC do?

First of all, it is necessary to say that DNSSEC is a DNS extension. This is mainly due to the fact that DNS works as a domain name system that is deployed with DNS servers and supports the exchange of information. Information is exchanged by entering a domain name (internet name) in the browser, and DNS translates this name into a number of numeric codes called an IP address. A problem that only takes a few seconds in the system, but translating and searching for information is enough to forge the user's false IP address.

Just as DNSSEC technology is used to protect against false domains. This system is based on the principle of asymmetric encryption, ie encryption and decryption.

If you want to register a Czech domain, you can do it through the selected registrar. The list of suitable registrars can be found in the CZ.NIC file. Therefore, when selecting, the role is also played by whether the registrar also provides DNSSEC.

Perhaps the registrar and TELE3 can provide this security, as well as many other Internet and telecommunication services.


These are services such as web hosting, serverhosting and related DNS hosting services, web hosting, FTP hosting, multi-brand hosting, server placement and rental, server monitoring, virtual servers, backup, server and service management, VoIP Voice Services and more.

As far as security is concerned, TELE3 uses IPv4 and IPv6 protocols and uses different TLD domains to develop servers for increased security. Therefore, DNS develops not only in the Czech Republic, but also in the US and Germany, creating a high quality device that prevents possible attacks.
