.ae is the Latin alphabet Internet country code top-level domain (ccTLD) for the United Arab Emirates. It is administered by .aeDA which is part of the UAE Telecommunications Regulatory Authority (TRA). The Arabic alphabet ccTLD of the UAE is .emarat.

The .AE domain was originally delegated to UUNET. Recognising the domain should be administered in the country, the domain was transferred in 1995 to Etisalat, following a brief period of administration by the United Arab Emirates University. Since that time, Etisalat, through its division the UAE Network Information Center (UAEnic), has been responsible for the operation of the .ae domain.

During GITEX 2006, the Telecommunication Regulatory Authority TRA announced that the .ae ccTLD (Country code top-level domain) management and operations will be re-delegated to the TRA from Etisalat/UAEnic, the current .ae ccTLD manager. A new entity called .ae Domain Administration (.ae DA) has been formed to take care of management and operations of .ae based on latest DNS and Domain Registry technologies. During January 2008, IANA officially re-delegated the .ae Domain to the TRA.

On 3 August 2008, the .aeDA took over the DNS and launched their services with the new registry system which supports registry–registrar model. Currently the .aeDA has accredited eight registrars from different parts of the world. For the first time, Internet users in the UAE will be able to register and manage their domain names under .ae automatically using an online system without going through manual process which used to take up to six weeks for domain registrations. As per .aeDA policies, current domain holders are allowed to transfer between registrars at no cost.

The .ae is the first ccTLD in the Arab region to use standard Registry-Registrar model and the .aeDA is the first registry in the region to use industry-standard Extensible Provisioning Protocol to manage its domains.
