.tt is the internet country code top-level domain (ccTLD) in the Domain Name System of the Internet for Trinidad and Tobago.
The Trinidad and Tobago Network Information Centre (TTNIC) allows registrations under tt for second-level domains, and for third-level domains under the following domains: co.tt, com.tt, org.tt, net.tt, biz.tt, info.tt, pro.tt, int.tt, coop.tt, jobs.tt, mobi.tt, travel.tt, museum.tt, aero.tt, tel.tt and name.tt.[1] Registration under the above domains is unrestricted and the registry does not require applicants to have a physical presence in Trinidad and Tobago. However, registrants with a foreign address are charged double.[2]
In addition, there is mil.tt, restricted to entities in the Military of Trinidad and Tobago, edu.tt is a registry for educational institutions in Trinidad and Tobago,[3] and gov.tt reserved for agencies of the government.
Domain hacks using .tt include ift.tt and mi.tt, URL shorteners used for IFTTT and the 2012 U.S. presidential campaign of Mitt Romney,[4] respectively.
