The .at top-level domain has a number ofsecond-level domains:

DomainIntended use
.ac.atReserved for academic institutions, especially universities
.gv.atReserved for the government as well as federal and state authorities
.co.atIntended for commercially-oriented companies
.or.atIntended for all kinds of organizations
.priv.atIntended for private Austrian individuals

However, it is also possible to register directly at the top level.

Known domain hacks

[edit]

Given the number ofEnglish words that end with -at, this presents the possibility for manydomain hacks.

Many Austriandomain names were registered forEnglish words that end with "at". Domain hacks treating "at" as a word in its own right (such asarrive.at) are widespread.

As of today, there are very few suchdomain names left available on the domain prime market as the result ofdomain name speculation.

Most of them can be bought on the domain secondary market. Only a few of thesedomain names are actually used.

Some known examples of the Austriandomain hacks are:

Properties

[edit]

An .at-Domain can be between one and 63 characters long. Registrations ofinternationalized domain names are accepted.[3]

In 2007, it was made possible to register domain names containing only numbers. The .at-Domain started usingDNSSEC in 2011 in order to guarantee the authenticity and integrity of theDomain 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]
