The domain name com is a generic top-level domain (gTLD) in the Domain Name System of the Internet. Its name is derived from commercial,[1] indicating its original intended purpose for domains registered by commercial organizations. However eventually the distinction was lost when .com, .org and .net were opened for unrestricted registration.

The gTLD com was originally administered by the United States Department of Defense, but is today operated by Verisign. Registrations in com are processed via registrars accredited by ICANN. The registry accepts internationalized domain names.

The domain was one of the original top-level domains (TLDs) in the Internet when the Domain Name System was implemented in January 1985, the others being edu, gov, mil, net, org, and arpa. It has grown into the largest top-level domain.[2]

Transfer procedures

Domains can be transferred between registrars. Prior to October 2006, the procedure used by Verisign was complex and unreliable – requiring a notary public to verify the identity of the registrant requesting a domain transfer. In October 2006, a new procedure, requiring the losing registrar to provide an authorization code on instruction from the registrant (also known as EPP code) was introduced by Verisign to reduce the incidence of domain hijacking.

Reliability

Websites with the URL .com may be trying to sell you a product or service. As a result many websites cannot always be deemed as safe.[citation needed]
