Second-level domains
editThe .at top-level domain has a number of second-level domains:
- .ac.at (reserved for academic institutions, especially universities)
- .gv.at (reserved for the government as well as federal and state authorities)
- .co.at (intended for commercially-oriented companies)
- .or.at (intended for all kinds of organizations)
- .priv.at (intended for private Austrian individuals)
However, it is also possible to register directly at the top level. Given the number of English words that end with -at, this presents the possibility for many domain hacks.
Known domain hacks
editMany Austrian domain names were registered for English words that end with "at". Domain hacks treating "at" as a word in its own right (such as arrive.at) are widespread. As of today, there are very few such domain names left available on the domain prime market as the result of domain name speculation. Most of them can be bought on the domain secondary market. Only a few of these domain names are actually used. Some known examples of the Austrian domain hacks are:
- donteat.at, a popular Foursquare service
- many.at, link bundler[citation needed]
- hailst.at, official website of Mississippi State Bulldogs athletics
Properties
editAn .at-Domain can be between one and 63 characters long. Registrations of internationalized domain names are accepted.[3] In 2007, it was made possible to register domain names containing only numbers. The .at-Domain started using DNSSEC in 2011 in order to guarantee the authenticity and integrity of the Domain Name System's data.
Before August 2016, it was only possible to register .at-Domains with three or more (two for co.at, ac.at, gv.at, or.at) characters.[4]
