Technical issues

The database and its relevant software is maintained and developed by the University of Vienna. The domain engineers of the Vienna University Computer Center (ZID) have been responsible for these tasks since the internet was launched in Austria. Thus, can rely on a profound experience and technical competence.

.at-Nameserver: practically failsafe

The database stores all registration data including the relevant nameserver data of its domains. This entry makes sure that a .at-domain is globally accessible. In addition, the data is transmitted to a redundant system of 8 nameservers. With the help of anycast these are reachable at more than 30 locations around the globe. This means that in case of problems with one nameserver, .at-domains are protected multiple times against a loss of information or non-availability. Furthermore the range of is being expanded continuously.

Quality counts and is verified invests much effort and know-how in a high data quality of its .at-domains. So, each domain application is verified by an automatic check. Even the nameservers of a domain are technically checked – during a registration and modification process. This enables us to maintain a high data quality and add new domains to our Domain Name System that are fully functional.

Continued system improvements

Database specialists and programmers are permanently engaged in making the domain administration more efficient – for us and for you. International contacts and involving the registry technology in scientific projects allow us to be technically up-to-date.

What are the technical reasons for the rejection of a domain application?

There are various reasons why an application may be rejected: errors in the application itself (incomplete field descriptions, missing mandatory fields, invalid version etc.), invalid domain names, wrong entry formats, invalid characters. The most frequent source of error is an incorrect nameserver configuration. Please click here for more information about the application check and nameserver configuration.

What does IDN mean?

IDN is for "Internationalized Domain Name", which is a standard that enables the use of other characters in addition to the currently allowed ASCII-characters (the 26 Latin letters, the ten numbers 0 – 9 and the hyphen) for domain names. The respective registry decides which additional characters are allowed with the implementation of IDN.
