Network Registrar supports enterprise IP address management. It automates IP address management, and thus creates a stable infrastructure that increases the reliability and efficiency of the address assignment process, and substantially diminishes the administrative burden associated with address management.
Network Registrar includes support for Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) servers, and provides many features that makes administering these servers easy.
DNS Registrar includes the following features:
DHCP Registrar includes the following features:
Registrar Administration includes the following features:

In addition, note the following other software-related requirements:
You can install Network Registrar on a Solaris server or on a Windows NT server or workstation.
You can run both the servers and GUI on either a Windows NT server or on a Solaris server. Or you can run the servers on one platform and the GUI on another. For example, you can run the servers on a Solaris server and the GUI on a Windows NT server or vice versa.
When you upgrade from a previous release of Network Registrar, you can choose to save your database or overwrite it. If you overwrite your database, you lose all information about your zones, scopes and leases.
 | Warning The upgrade procedures for Solaris have changed from earlier revisions. Do not run the Solaris pkgrm command before reviewing these instructions. The pkgrm command will delete your data. |
To upgrade from Network Registrar release 2.x or 3.x , you must run the program upgrade_cnr in the solaris subdirectory of the CD-ROM. If you use the standard configuration of the Solaris automounter, this program will be located in the directory /cdrom/nr_3_0r0/solaris/upgrade_cnr.
To upgrade from Network Registrar 2.x or 3.x to Network Registrar 3.5 on a Solaris server and to preserve your database, do the following:
Step 1 Insert the compact disk into your CD-ROM drive.
Step 2 Login as root.
Step 3 Run the /cdrom/solaris/upgrade_cnr program.
# /cdrom/solaris/upgrade_cnr
If you mount the CD-ROM manually or have a non-standard automounter configuration, then replace cdrom with the directory on which the CD-ROM is mounted (for example, cdrom/cnr_3_0_1_3_t).
Step 4 Press Enter to stop the Network Registrar servers.
Step 5 Enter the database backup directory or press Enter to accept the default.
Step 6 Type the username and password for your Network Registrar program.
The system prompts you whether you want to preserve the existing Network Registrar database.
Step 7 Type Y to specify yes and N to specify no.
If you type Y, the installation program preserves the database and loads it when you invoke the newly installed version of Network Registrar.
 | Caution If you type N, all data in the Network Registrar database is deleted. |
Step 8 Type Y to continue with the upgrade.
The system removes the existing Network Registrar database and informs you when the removal is successful. It then installs the new release of Network Registrar in the previous location of the program.
Step 9 When prompted to preserve the database backup, type Y or N.
At this point, the installation program has already copied the backup database to the Network Registrar directory. Preserving the database backup is not essential to preserving your data. If you type Y, the system displays the location of the backup database (for example, /usr/tmp/cnr_db.bak).
This completes the procedure for upgrading from Network Registrar 2.x or 3.x to Network Registrar 3.5 on a Solaris server. When the upgrade is complete, Network Registrar's services starts automatically.
To upgrade from Network Registrar 2.x or 3.x to Network Registrar 3.5 on a Windows NT server and to preserve your database, do the following:
Step 1 Insert the compact disk into your CD-ROM drive.
Step 2 Run setup.exe.
Step 3 Click Next when the welcome screen appears, then Next again at the copyright notice.
Step 4 Click Yes to stop the Network Registrar servers.
Step 5 Choose what type of installation you want and click Next.
Step 6 Answer Yes to the question about upgrading your existing installation. This preserves the data in your database.
Step 7 Select the Program Folder for Network Registrar. The default is the existing folder for the previous installation.
Step 8 Click Next to begin installing the system files.
Step 9 When prompted, supply your Network Registrar username and password.
Step 10 Specify whether you want to read the ReadMe file or not.
Step 11 Click Yes to restart Windows.
To upgrade from Network Registrar 2.x or 3.x to Network Registrar 3.5 on a Windows NT server without preserving your database, do the following:
Step 1 Run the uninstall program.
Step 2 Perform an initial installation as described in "Installing Network Registrar on Windows" section.
To install the Network Registrar servers and/or the GUI do the following:
Step 1 Insert the compact disk into your CD-ROM drive or mount the CD-ROM from your remote server.
Step 2 Become the root user by typing su, and then typing the root password.
Step 3 Type the pkgadd command with the -d option that specifies the CD-ROM directory:
# pkgadd -d <cdrom>/solaris/see_readme_before_using
where cdrom is the directory on which the CD-ROM is mounted (for example, cdrom/cnr_3_0_1_3_t). For additional information on the exact directory location, see the file README.solaris in the top-level directory of the CD-ROM.
The installation prompts you for the package you want to install.
Step 4 Select All or the default.
Step 5 Select server and GUI, or server, or GUI.
Step 6 Choose the location of the following directories or accept the defaults.
If the directories do not exist, the installation asks if you want them created. Choose to have the installation create them for you.
Step 7 The installation informs you that it will install scripts that will run as the superuser. Answer Yes. If you answer No, the installation will abort.
Step 8 If you are upgrading Network Registrar from a previous release, answer No to the question whether to overwrite the existing database.
Step 9 The installation copies all the files, and starts the AIC Server Agent, which in turn starts the Network Registrar servers.
Step 10 The installation displays a message informing you that the installation was successful.
Step 11 The installation returns to the opening prompt. Click q to quit the pkgadd program.
For a list of all the files that comprise Network Registrar, see "Network Registrar Information."
To check the status of the Network Registrar servers run the /opt/nwreg2/usrbin/aicstatus command. For information about this command, see "Starting the AIC Server Agent on Solaris" section.
To install the Network Registrar server and/or the GUI on Windows, do the following:
Step 1 Insert the compact disk into your CD-ROM drive.
Step 2 Double-click setup.exe from the Explorer directory window for your CD-ROM drive.
Step 3 Click Next when the welcome screen appears, then Next again at the copyright notice.

Step 6 Select the Program Folder for Network Registrar. The default is the existing folder for the previous installation.
Step 7 Click Next to begin installing the system files.
Step 8 When prompted, supply your Network Registrar username and password.
Step 9 Specify whether you want to read the ReadMe file or not.
Step 10 Click Yes to restart Windows.
To run Network Registrar you need to start Network Registrar's services. You can do this by doing either of the following:
To start Network Registrar's DNS and DHCP servers on Solaris, start the AIC Server Agent as follows:
Step 1 Become superuser.
Step 2 Change to the /etc/init.d directory.
Step 3 Type the aicservagt command with the start argument:
./aicservagt start Starting AIC Server Agent for Network Registrar
Step 4 Check that the servers are running, by typing the aicstatus command:
/opt/nwreg2/usrbin/aicstatus DNS server running (pid: 649) MCD server running (pid: 648) DHCP server running (pid: 650) Server Agent running (pid: 647) MCD Lock Manager running (pid: 651)
To start Network Registrar's DNS and DHCP servers on Windows NT, start the AIC Server Agent as follows:
Step 1 From the Program Manager, select Start>Settings>Control Panel.
Step 2 From the Control Panel, click Services.
Step 3 From the Service list, select AIC Server Agent 2.0.
Step 4 Click Start.
Step 5 Click Close.
To start Network Registrar you need to start the program and log in to a cluster. A cluster is a DNS and/or DHCP server that share the same Network Registrar database. Adding a cluster tells Network Registrar about the existence of a cluster. To configure or administer the cluster you must also connect to it.
You can start the Network Registrar GUI at anytime---the servers do not need to be running. You cannot save any changes however, unless the servers are running.
Step 1 Type the following at the command line:
/opt/nwreg2/usrbin/ntwkreg
Network Registrar displays the Server Manager.
Step 2 Click Add to add a new cluster.
Step 3 In the Login to cluster dialog box, enter the username admin and the password changeme.
Step 4 Enter your license key.
For more information about licensing, see the "Entering Network Registrar License Key" section.
Step 1 Select Start>Programs>Network Registrar.
Step 2 In the Login to cluster dialog box, enter the username admin and the password changeme.
Step 3 Enter your license key.
For more information about licensing, see the "Entering Network Registrar License Key" section.
Step 1 From the Admin menu, select Clusters.
Step 2 In the Cluster dialog box, click the Add Cluster button.
Step 3 In the Add Cluster dialog box, enter the cluster name. This name is either "localhost" or the host (DNS) name of the machine on which Network Registrar is installed.
Step 4 If you want to connect the cluster at this time, select the Connect to this cluster check box.
Step 5 Click OK.
Step 6 In the Login for Cluster dialog box for that cluster, enter the username and password.
Step 7 Click OK.
Step 1 From the Admin menu, select Clusters.
Step 2 In the Cluster dialog box, click the Add cluster button.
Step 3 In the Add Cluster dialog box, enter the cluster name.
The cluster name must be the name of the host on which the database runs. This is usually the name of the DNS server.
Step 4 If you want to connect the cluster at this time, select the Connect to this cluster check box.
Step 5 Click OK.
Step 6 In the Login for Cluster dialog box for that cluster, enter the username and password.
Step 7 Click OK.
Step 8 From the License dialog box, click New Key.
Step 9 From the Cluster Properties dialog box, select Edit License Key.
