This window is used to define a new host for a reverse lookup zone.
Follow the steps below.
1. In the Entry Name field, specify the host portion of the IP address of this
entry.
2. In the Fully-Qualified Name Entry field, specify the domain name of the
host. Be sure to type the fully-qualified domain name of the host.

Reverse Addresses table and maps an IP address to a host name.

This window is used to delete a host from the selected zone. The

to save your changes and exit the window. (To cancel your changes,
