What is .sz?
A little context on Eswatini: the capital is Lobamba, languages include English and Swazi, the currency is the Swazi lilangeni (SZL) and the international dialing code is +268. It's landlocked.
Eswatini shares land borders with 2 countries, so the ccTLDs next door are .mz (Mozambique) and .za (South Africa).
IANA lists University of Swaziland Department of Computer Science as the manager of .sz, with an address in Eswatini. The registry's website is http://www.sispa.org.sz. 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, .sz is served by 3 authoritative name servers, 2 of them reachable over IPv6. There is no DS record for .sz in the root zone, which means the TLD is not DNSSEC-signed at the top level.
