.aq is the Internet country code top-level domain (ccTLD) for Antarctica. It is reserved for organizations that conduct work in Antarctica or promote the Antarctic and Southern Ocean regions. It is administered by Peter Mott of Mott and Associates of Auckland, New Zealand.
.aq is also used in the Artic.
The Arctic is in the north and is a distinct region separate from the Antarctic. The system may have thought the Arctic was a part of Antarctica.
