• Registry/operator: Network Information Center - Paraguay (NIC-PY).
• Sponsor: Centro Nacional de Computación, Universidad Nacional de Asunción.

Usage and Audience

• Actual use: fairly popular within Paraguay.
• Also sees some use by websites related to the Python programming language (due to the .py string match).

Registration Rules

  • Registrations are at the third level beneath second-level labels (e.g., name.com.py).
  • Second-level registrations are prohibited.

• Eligibility and restrictions:

  • Any individual or legal entity, national or foreign, may apply for delegation under .py.

  • edu.py
  • mil.py
  • gov.py

• Classification noted by registry sources:

  • Some SLDs are described as restricted (examples cited: .net.py, .com.py) intended for specific sectors.
  • Other SLDs require supporting documentation and are reserved for particular institution types (examples cited: .edu.py, .gov.py, .mil.py, .coop.py, .org.py).
