The .nu TLD is the country-code domain for Niue, a self-governing island nation in free association with New Zealand. Despite its official association with Niue, it is primarily used by users in Scandinavia and other European countries because 'nu' means 'now' in Swedish, Danish, and Dutch. It is one of the few ccTLDs with significant international usage due to its linguistic appeal.

The .nu domain was delegated to the Internet Users Society Niue (IUSN) in 1997. In the late 1990s, American businessman Bill Semich gained control through a controversial agreement with Niue’s government, promising internet access in exchange for domain revenues. After Niue canceled the deal in 2000, Semich retained control until 2013, when the Swedish Internet Foundation took over operations. In 2018, Niue sued for control and damages, but in March 2024, a Stockholm court ruled in favor of the Swedish Internet Foundation, finding no legal wrongdoing and ordering Niue to cover court costs.
