What is .pr?
A little context on Puerto Rico: the capital is San Juan, languages include English and Spanish, the currency is the United States dollar (USD) and the international dialing code is +1.
IANA lists Gauss Research Laboratory Inc. as the manager of .pr, with an address in Puerto Rico. The registry's website is http://www.nic.pr. 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 8 name servers for .pr, every one of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .pr haven't been tampered with on the way. Registration data is published over WHOIS (the WHOIS server is whois.afilias-srs.net).
