What is .er?
A little context on Eritrea: the capital is Asmara, languages include Arabic, English and Tigrinya, the currency is the Eritrean nakfa (ERN) and the international dialing code is +291.
Eritrea shares land borders with 3 countries, so the ccTLDs next door are .dj (Djibouti), .et (Ethiopia) and .sd (Sudan).
IANA lists Eritrea Telecommunication Services Corporation (EriTel) as the manager of .er, with an address in Eritrea. 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, .er is served by 3 authoritative name servers, 1 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .er, which lets validating resolvers check its answers cryptographically.
