Managing DNS Zones and Zone Transfers

What Are DNS Zone Types?
          There are four DNS zone types:
          • Primary
          • Secondary
          • Stub
          • Active Directory–integrated
     Primary Zone

The main area is a place where DNS server is the host and masters this source of information about the area. In addition, storing DNS server a master copy Any data files or AD DS in the local area. When the primary DNS server zone file at the storage file , by default named zone_name.dns , And is located in % WINDIR % \ System32 \ DNS folder on the server . When the area is not stored in AD he DS, which is a unique copy of the database writable DNS server.

     Secondary Zone

Second place was a place where DNS server host, but for the second resource Information Area. You need to get information about it from another remote server for the zone also bringing the DNS server for the zone. This DNS server must have network access to remote DNS servers receiving updated information area. Because a secondary zone is a copy of another major area Server host secondary zones cannot be stored in AD DS. If you have a second zone may be useful Copy data from non -Windows DNS zone.

     Stub Zone

A stub zone is a zone that contains only those resource records replica it is necessary to identify the authoritative DNS server for the zone. Stub zone to resolve a single name DNS namespace, when a corporate merger requires that the DNS server may be required Customer Name two separate DNS namespaces resolve two namespace.
A stub zone consists of the following components:
• Delegate places SOA resource record, NS resource records, and a resource records.
• You can use the IP address to update the stub zone one or more master servers.
Master server stub zone is a child of one or more authoritative DNS server’s zone.
It is usually delegated domain DNS server hosting the primary zone.
     Active Directory–Integrated Zone
If AD DS stores the zone data, then DNS can use the multimaster replication model to replicate
the primary zone data. This enables you to edit zone data on more than one DNS server simultaneously.
