By the term DNS zone, a certain portion or administrative space within the global Domain Name System is referred. Through certain entities, a boundary of authority subject to management is represented by each DNS Zone. All the DNS zones are organized in a tree-like order according to the hierarchy of cascading lower level domains, from the DNS namespace. The authority over each and every DNS zone is linked to either certain legal entity or organization (which is a country-code top-level domain registry) or a company or an individual which has access to a certain subdomain within the system. DNS zone can consist of one or more than one domain or sub-domains depending on the administrative rights delegated to a specific entity. As per necessity, over a sub-space further authority could be delegated.
This feature named Deleting DNS zones allows deleting DNS zones from a particular server. This is very useful to remove a certain domain which is no longer is in use or if some other DNS server is authoritative for the domain. We have to keep in mind that those DNS zones which reside on other ‘write-only’ DNS servers in a DNS cluster won’t appear in this interface.
These steps should be followed to delete a single DNS zone.
To select the zones from the menu, in Mac use command-click or in Windows use control-click in order to select multiple zones. If the zones which are desired to be deleted are grouped together, first desired zone is to be clicked at first then shift-click the last zone, in this way all the zones in between will be selected.
Management of DNS Zones includes so many tasks, from defining the name hierarchy within the zone to maintain the registration procedures keeping the operations of the DNS servers intact. According to the size of authority which stands behind a specific DNS zone, the amount of management actions varies.
