.in is the Internet country code top-level domain (ccTLD) for India. It was made available in 1989, four years after original generic top-level domains such as .com, .net and the country code like .us. It is currently administered by the National Internet Exchange of India (NIXI).

Registry operator
The domain was originally managed by the National Centre for Software Technology (NCST) and its Centre for Development of Advanced Computing (C-DAC). The Government of India issued an executive order in 2004 to transfer responsibility for managing .in domains to the newly created INRegistry under the authority of the National Internet Exchange of India (NIXI). The National Informatics Centre (NIC), ERNET, and the Ministry of Defence were appointed as registrars for the gov.in, res.in and ac.in, and the mil.in domains respectively.

In August 2018, NIXI appointed Neustar Data Infotech (India), a subsidiary of Neustar Inc, to be the country's new registry services provider. Neustar completed migration of existing .in domains to its registry infrastructure in March 2019. Neustar added the ability to register Indian-language domains in native script by enabling end-to-end web portal language support.

By October 2011, the number had surpassed 1 million domain names. , the number has more than doubled to over 2 million domain names.

Restrictions on use of .in domains 
As per the terms and conditions of the  registry, domain privacy is not allowed.

Recently updated EKYC guidelines were issued to all registrars to authenticate new registrants. Hence, the previous rule relating to bulk booking of .in domain names has been withdrawn. Now customers can book unlimited .in domain names as previously in line with promoting .in TLD on par with other popular TLDs like .com and others which also has no restrictions relating to bulk booking.
