Name (uses parent domain name if blank)

The single-part name for a host (a computer or other device) in this zone. If this box is blank, the host name is the same as the parent domain name. If you need to add a name here that contains a period (.) to indicate the name of an additional domain level, first add the additional domain separately in DNS Manager and then add a new host record there as a single-part name.

Fully qualified domain name (FQDN)

The domain name to which this resource record applies. The FQDN uniquely identifies the DNS hierarchical tree by specifying a list of names that are separated by dots in the path from the referenced domain or host to the root.

IP address

Provides a space for you to type the IP address for the host that you specify in Name. The DNS server does not attempt to verify the existence of the host that is represented by this IP address. If you supply an Internet Protocol version 4 (IPv4) address, the DNS server creates a host (A) resource record. If you supply an Internet Protocol version 6 (IPv6) address, the DNS server creates an IPv6 host (AAAA) resource record.

Create associated pointer (PTR) record

Creates a resource record in the reverse lookup zone. A pointer (PTR) resource record maps a reverse DNS domain name based on the IP address of a computer that points to the forward DNS domain name of that computer.

Allow any authenticated user to update DNS records with the same owner name

When this option is selected, it permits the resource record to be updated dynamically. When the update is performed, the host that requests the update is granted permission to modify the resource record, but all other nonadministrative permissions are removed from the access control list (ACL) that protects the resource record. This makes it possible for the administrator to create a secure resource record for a host that is not yet online and still enable the resource record to be updated dynamically when the host obtains its IP address through Dynamic Host Configuration Protocol (DHCP).
