What is .st?
A little context on São Tomé and Príncipe: the capital is São Tomé, the main language is Portuguese, the currency is the São Tomé and Príncipe dobra (STN) and the international dialing code is +239.
IANA lists Tecnisys as the manager of .st, with an address in Sao Tome and Principe. The registry's website is http://www.nic.st. 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.
On the technical side, .st is served by 4 authoritative name servers, every one of them reachable over IPv6. There is no DS record for .st 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.nic.st).
