.IN domain is the Internet country code top-level domain ( ccTLD ) for India and is available for registration to anyone; companies, individuals and organizations in India. The domain is operated by INRegistry under the authority of NIXI, the National Internet Exchange of India . INRegistry was appointed by the government of India.

As of 2005 , liberalised policies for the .IN domain allow unlimited second-level registrations under .IN . Unlimited registrations under the previously structured existing zones are also allowed:

• .in (This Indian domain is available to anyone; used by companies, individuals, and organizations in India)
• .co.in (This Indian domain is originally for banks, registered companies, and trademarks in India)
• .firm.in (This Indian domain is originally for shops, partnerships , liaison offices, sole proprietorships in India)
• .net.in (This Indian domain is originally for Internet service providers of India)
• .org.in (This Indian domain is originally for non-profit organizations in India)
• .gen.in (This Indian domain is originally for general/miscellaneous use for Indians)
• .ind.in (This Indian domain is originally for individuals)

Before the more liberal policies for the .in domain, only 7000 names had been registered between 1992 and 2004. By the end of 2006 , that number had increased to over 200,000, with names registered by web users in over 150 countries. Roughly 80% of the registrants are from India, Germany, and the United States.

The domain .nic.in is reserved for India's National Informatics Centre , but in practice most Indian government agencies have domains ending in .nic.in .

Due to the popularity of the word "in" in English , German and other languages, and the commonness of words ending in "in", the .in ccTLD has become popular in the creation of domain hacks .
