DNS servers

Challenges

In order to allow the greatest possible number of users to use their .lu domain name easily and reliably, the Restena Foundation provides its community - which consists of players in the fields of research and education, health, culture and administration in Luxembourg - as well as the users (individuals and companies) of its my.lu platform (via its registrar activity) with a set of servers that are "authoritative" for these domains.

These servers contain and distribute information about each .lu name registered in the domain name system (DNS), such as the address of the website or the mail server to which electronic messages must be sent for this domain.

Features

In order to guarantee a high level of availability of the services associated with each domain name, the Restena Foundation offers:

• its community three administered servers, which are situated in different networks and geographical locations (two in Luxembourg, one in Europe);
• my.lu users two administered servers, which are situated in different networks and geographical locations, and a group of servers distributed across Europe (anycast).

The information provided by all these servers is automatically synchronised with the information entered in the management interface of zones hosted on the DNS servers of the Restena Foundation (DNSGUI) or communicated from your own "authoritative" DNS server if you already possess one for your domain.

The domains that use this service can benefit from DNSSEC (domain name system security extensions) technology. The information hosted in this way is authenticated by cryptographic keys that guarantee the flawless integration of each domain into a chain of trust within the tree view of the naming system on the internet, and which protect you from attacks that aim to misappropriate your domain name or your associated services
