What is .sl?
A little context on Sierra Leone: the capital is Freetown, the main language is English, the currency is the Sierra Leonean leone (SLE) and the international dialing code is +232.
Sierra Leone shares land borders with 2 countries, so the ccTLDs next door are .gn (Guinea) and .lr (Liberia).
IANA lists Sierratel as the manager of .sl, with an address in Sierra Leone. The registry's website is https://www.nic.sl. 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, .sl is served by 2 authoritative name servers, none of them with an IPv6 address. There is no DS record for .sl in the root zone, which means the TLD is not DNSSEC-signed at the top level.
