.mo is the Internet country code top-level domain (ccTLD) for Macau. The inclusion of the letter "o" in the TLD refers to the alternate spelling of Macao.
The registry for this domain name is operated by the Macao Network Information Center (MONIC). Operated by the University of Macau since 1992, MONIC administers the registration of the country-code domain names ccTLD.
To further promote the steady development of services, Macao SAR government changed the operation entity of MONIC. Effective from 12 March 2011, HNET Asia Limited [1] appointed by the Macao SAR government, is responsible for the operating MONIC.
However, second-level domain is only available for the registrants who has registered a same name at third-level.
