What is .es?
Why .es? The letters come from España, the Spanish name for Spain.
A little context on Spain: the capital is Madrid, the main language is Spanish, the currency is the Euro (EUR) and the international dialing code is +34.
Next door on the map, you'll find .ad for Andorra, .fr for France, .gi for Gibraltar, .pt for Portugal and .ma for Morocco.
IANA lists Red.es as the manager of .es, with an address in Spain. The registry's website is http://www.nic.es. 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.
Under the hood, the root zone points to 4 name servers for .es, every one of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .es haven't been tampered with on the way. Registration data is published over WHOIS (the WHOIS server is whois.nic.es).
