root is the name of a database record of the root zone in the Domain Name System of the Internet that was occasionally used as a diagnostic marker. Its presence demonstrated the root zone was not truncated upon loading by a root nameserver.
According to technical observers the single .root entry was replaced in 2006 with just vrsn-end-of-zone-marker-dummy-record, to be reintroduced later in 2006 in its original form. The entry was deleted again during the preparations for the deployment of DNSSEC at the root zone in 2010.
