What is .sn?
A little context on Senegal: the capital is Dakar, the main language is French, the currency is the West African CFA franc (XOF) and the international dialing code is +221.
Senegal shares land borders with 5 countries, so the ccTLDs next door are .gm (Gambia), .gn (Guinea), .gw (Guinea-Bissau), .ml (Mali) and .mr (Mauritania).
IANA lists Universite Cheikh Anta Diop as the manager of .sn, with an address in Senegal. The registry's website is https://www.cctld.sn. 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, .sn is served by 6 authoritative name servers, 3 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .sn, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.sn).
