What is .py?
A little context on Paraguay: the capital is Asunción, languages include Guaraní and Spanish, the currency is the Paraguayan guaraní (PYG) and the international dialing code is +595. It's landlocked.
Paraguay shares land borders with 3 countries, so the ccTLDs next door are .ar (Argentina), .bo (Bolivia) and .br (Brazil).
IANA lists NIC-PY as the manager of .py, with an address in Paraguay. The registry's website is http://www.nic.py. 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, .py is served by 5 authoritative name servers, 4 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .py, which lets validating resolvers check its answers cryptographically.
