A Primary DNS zone is required for DNS name resolution and is both the authoritative for the zone and the primary point of contact for the zone.
A secondary zone are not authoritative and is a read only copy of the primary zone.
Zone data can be stored in Active Directory or in a zone files in %windir%/system32 /dns. The files name is zonename.dns
The zone can be either a Forward lookup (Name to IP address) or reverse lookup (IP address to name)

Add-DnsServerPrimaryZone -Name ‘TailspinToys.com’ -ReplicationScope ‘Forest’ -DynamicUpdate ‘Secure’
-ReplicationScope Forest, Domain
– ZoneFile Specify name of the zone file
To create a reverse lookup zone
Add-DnsServerPrimaryZone -NetworkID 192.168.10.0/24 -ReplicationScope ‘Forest’ -DynamicUpdate ‘Secure’
