About DNS zones

DNS zones specify the domain name boundaries in which a DNS server has authority to perform name translations. Each zone contains records that specify how to resolve the host names associated with the zone or domain.

- Important: If you add records to an alias zone (that is, a zone added to an alias domain), before you remove the alias domain, make sure you manually migrate all the records to another zone.

You can add and remove zones through the Site Administrator control panel.
