About Authoritative Zone s
An authoritative zone is a zone for which the local (primary or secondary) server references its own data when responding to queries. The local server is authoritative for the data in this zone and responds to queries for this data without referencing another server.
There are two types of authoritative zones:

• Forward-mapping – An authoritative forward-mapping zone is an area of domain name space for which one or more name servers have the responsibility to respond authoritatively to name-to-address queries.
• Reverse-mapping – A reverse-mapping zone is an area of network space for which one or more name servers have the responsibility to respond to address-to-name queries.
