About DENIC

Technical Expertise

Designed for Security and Stability

We operate an important component of the Internet infrastructure. Therefore, high demands are placed on our technical expertise and equipment. Our systems must be very powerful, but also highly secure, since they have to be reliably available at any time.

Our registration system handles about two million transactions every month (new registrations, updates or deletions of domain data). These requests are transmitted to a central domain database, in which all domain data is stored. From this database, the technical information for our servers – the so-called name servers – is generated and sent to these servers several times a day. Our servers are distributed all over the world and respond to more than seven billion queries every day, i. e. each location handles an average of some 6,000 queries per second.

Permanent monitoring of service availability is another essential part of our security concept: The ongoing operation is monitored on a 24/7/365 basis to guarantee the performance and stability of all services around the clock.

Since our technical infrastructure is equipped with ample capacity, we also place it at the disposal of others and offer our Anycast Nameservice to other top level domains.

Redundant Infrastructure with 2 Data Centers

Security and redundancy are of crucial importance to all of DENIC's services: This is why we operate two data centers that work independently of each other. All relevant services are implemented both in our data center in Frankfurt and in the backup data center in Amsterdam. A storage area network (SAN) ensures that the corresponding data is available at both data centers, which are linked by a number of dedicated lines. Switching between the two identical environments in Frankfurt and Amsterdam is possible within just a few minutes, for all server locations. This brings big advantages: higher flexibility in case of scheduled maintenance and more security in case of a system error of failure.

Geared Towards Virtualisation and Automation

As regards the technical platform of our services, we place great importance on virtualisation technologies and automation of processes. When it comes to operation, monitoring, testing and implementation of new features – we rely consistently on the development and operation paradigm "Continuous Integration & Deployment" (CID):

  • Updates and patches may be deployed in automated routines and as required
  • In automated tests, all components and services of the system are checked
  • Also during maintenance, services can continue to operate, virtually without interruption
