Domain Name System Security Extensions (DNSSEC) are used to digitally sign domain name server data. This makes DNSSEC an important and indispensable technology for all customers who depend on the operating data of their domain names being transmitted to the customer in an unaltered form.

123domain.eu was involved in the "DNSSEC Testbed for Germany" and is playing its part in accelerating the introduction of DNSSEC and simplifying its use. To this end, we support DNSSEC for most domain endings, offer our customers automated processes for signing and key changes and advise companies and authorities on the introduction and use of DNSSEC.
