.ntt Domain Information

Country flagLogo for .ntt Domain

Telecommunications, data centers, and IT services sit behind .ntt, a three-letter closed extension from ICANN's 2012 New gTLD Program. Telecom groups operating both consumer networks and enterprise infrastructure carry two distinct exposures at once: subscriber account credentials on one side, and on the other, service endpoints referenced inside customer systems where a spoofed address compromises the infrastructure itself.

Use covers group and business-unit content, network and data centre services, enterprise destinations, and country sites. Registration is closed to the public and the extension carries no aftermarket. Japanese participation in the round was unusually systematic across carriers, manufacturers, and registry operators alike.
