What is .澳門?
IANA delegated .澳門 on February 11, 2016, as part of the effort to let people use domain names entirely in their own script.
A little context on Macau: languages include Portuguese and Chinese, the currency is the Macanese pataca (MOP) and the international dialing code is +853.
Next door on the map, you'll find .cn for China.
IANA lists Macao Post and Telecommunications Bureau (CTT) as the manager of .澳門, with an address in Macao. The registry's website is https://www.monic.mo. ccTLD managers set their own policies — who can register, which second-level names exist, pricing to registrars — so those rules differ from country to country.
Under the hood, the root zone points to 7 name servers for .澳門, every one of them reachable over IPv6. There is no DS record for .澳門 in the root zone, which means the TLD is not DNSSEC-signed at the top level. Registration data is published over WHOIS (the WHOIS server is whois.monic.mo).
Macau also has another country-code domain in the root zone: .mo.
