A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Domain names are used in various networking contexts and application-specific naming and addressing purposes.
.com is a top-level domain (TLD) in the Domain Name System of the Internet. Its name is derived from the word commercial, indicating its original intended purpose for domains registered by commercial organizations. Later, the domain opened for general purposes.
.in is the Internet country code top-level domain (ccTLD) for 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.
.org is a generic top-level domain (gTLD) of the Domain Name System (DNS) used in the Internet.
The name is truncated from organization. It was one of the original domains established in 1985, and has been operated by the Public Interest Registry since 2003. The domain was originally intended for non-profit entities, but this restriction was not enforced and has been removed. The domain is commonly used by schools, open-source projects, and communities, but also by some for-profit entities.
