Nameserver configuration

In order to register a domain, nic.at requires at least two correctly configured name servers. The configuration is also checked during each proximate modification of data. Errors in name server configuration result in the rejection of domain applications. The check categories for name server checks are described under the heading automatic application check.

DNS Software

The most popular domain name server (DNS) software is BIND, which manages the DNS service within the network. The operating systems of many name servers are based on various Unix derivates. Ports of newer BIND versions (8.x and 9.x) for Windows NT or 2000 are also available. As a principle, the latest BIND version should be installed (as for any software), because newer versions usually take into account safety gaps and other problems.
