Niue uses two country-code Top-Level Domains (ccTLDs): .nu and .co.nu. The official ccTLD is .nu, operated by the IUSN Foundation (Internet Users Society - Niue), and can be registered by anyone worldwide. Due to the word "nu" meaning "now" in Scandinavian languages, the .nu extension is popular in Nordic countries and the Netherlands, often used for creative domain hacks. The .co.nu domain is another second-level domain associated with Niue, known for being freely available globally and seen as an alternative to .com, though it is not officially recognized by ICANN.
