Domain of Origin

The parent DNS domain name that is used to root either a zone or a resource record within a zone. This name is joined to the end of unqualified or relative domain names to form a fully qualified domain name (FQDN) within the zone. In DNS Manager, the domain of origin

will correspond to Zone name as it appears in the Add Zone Wizard or the name that appears in the Parent domain name field for any resource records created within the zone.
