.nu is the Internet country code top-level domain (ccTLD) assigned to the island state of Niue. It was one of the first ccTLDs to be marketed to the Internet at large as an alternative to the gTLDs .com, .net, and .org. Playing on the phonetic similarity between nu and new in English, and the fact that nu means "now" in several northern European languages, it was promoted as a new TLD with an abundance of good domain names available. The .nu domain is now controlled by the Internet Foundation in Sweden amid opposition from the government of Niue.

The Domain Name System of the Internet consists of a set of top-level domains that constitute the root domain of the hierarchical name space and database. In the growth of the Internet, it became desirable to expand the initial set of six generic top-level domains in 1984. As a result, new top-level domain names have been proposed for implementation by ICANN. Such proposals included a variety of models ranging from adoption of policies for unrestricted gTLDs that could be registered by anyone for any purpose, to chartered gTLDs for specialized uses by specialized organizations. In October 2000, ICANN published a list of proposals for top-level domain strings it had received.
A geographic top-level domain is any of an unofficial group of top-level domains in the Domain Name System of the Internet using the name of or invoking an association with a geographical, geopolitical, ethnic, linguistic or cultural community. The IANA does not recognize these domains as their own group within the Root Zone Database, rather classifying them as generic top-level domains.
