The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as .com, .info, .net, .edu and .org and the country code top-level domains (ccTLDs) e.g. ‘.in’ for India. Below these top-level domains are the second-level and third-level domain names that may be reserved by end-users. The registration of these domain names is usually administered by domain name registrars.

The Internet Corporation for Assigned Names and Numbers (ICANN) is responsible for the coordination of the global internet's systems of unique identifiers and, in particular, ensuring its stable and secure operation, achieving broad representation of the global internet community; and to develop appropriate policies. The .IN Registry is the official registry in India responsible for maintaining the top level domain, “.in”. The .IN Registry has been created by NIXI, the National Internet eXchange of India, a not-for-profit company, with the objective of facilitating improved internet services in the country. Second-level domains available in India include .co.in, .firm.in, .gov.in, .org.in, .gen.in. “.in” domains may be registered for one (1) to ten (10) years and renewed thereafter. No legislation has been enacted in respect of .in ccTLD.

Domain name disputes arising out of the registration and use of the .in Internet Domain Name may be resolved through .IN Domain Name Dispute Resolution Policy (INDRP). Any person who considers that a registered domain name conflicts with his legitimate rights or interests may file a complaint with the .IN Registry on the following premises:

the Registrant's domain name is identical or confusingly similar to a name, trademark or service mark in which the Complainant has rights;

the Registrant has no rights or legitimate interests in respect of the domain name; and

the Registrant's domain name has been registered or is being used in bad faith.

The remedy available is limited to requiring the cancellation of the Registrant's domain name or transfer to the Complainant. Costs, if deemed fit, may be awarded.
