For a domain-registration they require the following information:
Billing Contact (usually the provider)
Domain Owner (e.g. the company)
Admin Contact (usually the IT-department of a Company)
Tech Contact (technical contact, we always use the provider)
Zone Contact (the one responsible for the DNS-Servers)
Nameserver (the Nameservers)
nic.at is capable of entering 5 nameservers per domain. There are no
restrictions regarding the IP-Adresses of these Nameservers as long as
they are not the same.
If you have these informations, there is a webinterface, that can be
found at www.nic.at, where you can enter all these Informations. Shortly
after entering the date a script at nic.at checks the nameservers for
the SOA records. If there are errors you get an e-mail containing an
error-report. This means you have to enter the Resource Records into
your nameservers before registering a domain.
If the checks are done successfully, the domain will be entered in their
nameservers (for example ns1.univie.ac.at). These nameserver are
reloaded at: 10:00am, 1:30pm, 5:30pm and 10:00pm every day.
Bernhard Graf reported, in March 2005, that nic.at requires TCP service.
