The “.es” domain portal published instructions from the general director of Red.es on how to install DNSSEC security protocols for “.es” domain names. This new system, aimed at improving security for ".es" domain names, will come into operation on 8 July, once the public notification period is over and the relevant international organisations and accredited registrars have been notified.

The Domain Name System, or DNS, is an essential part of browsing the internet, as it identifies websites (a name) and relates them to their IP addresses (a number). DNSSEC is a set of security extensions that add asymmetric encryptions to the previous system, ensuring the website you visit is the one typed into your browser.

DNSSEC is being installed all over the world due to the vulnerability of the DNS, which allows cyber crime offenders to reroute users to undesired websites.

The new service is optional and will be implemented gradually. We recommend you contact our accredited registrars to process your application.

In order to test whether DNSSEC has been activated on a website, you can use a number of free tools available from different organisations, such as the Internet Society. If a website uses DNSSEC, a small padlock will be shown next to the URL.

Our portal also has a section with FAQs about DNSSEC.
