Add/Change an IP Address Range

EasySpooler gives you the option of setting up IP address ranges for printer discovery. You may want to use IP address ranges for any of the following reasons:

To divide a large network into sections and complete discovery in stages, rather than using SNMP broadcast.
To identify specific, named, sections of a network and query them in combination or individually.
To probe addresses located beyond a router in another subnet to which a broadcast query would not be propagated.
To locate specific printers that did not respond to SNMP broadcast requests.
To discover new printers without using SNMP broadcast.

When you set up IP address ranges, you have various options for discovery:

You can create one or more IP address ranges and add more as needed.
You can enable an address range when you create it or later when you want discovery to search that range.
You can probe addresses located beyond a router in another subnet to which a broadcast query would not be propagated.
You can locate specific printers that did not respond to SNMP broadcast requests.
You can discover new printers.

NOTE: You can use both SNMP broadcast and IP address ranges for discovery. EasySpooler uses SNMP broadcast if the box in front of Use SNMP broadcast is checked on the Printer Discovery window. Using both SNMP broadcast and IP address ranges results in finding all printers that can be found by SNMP broadcast, plus printers found through the enabled IP address ranges. This dual approach can take a significant amount of time to complete on large networks.

To add an IP address range:

Click Destination in the main menu and select Printer Discovery from the menu options. The Printer Discovery page opens.
If you do not plan to use both SNMP broadcast and IP address ranges for discovery, remove the check mark after Use SNMP broadcast. Otherwise, leave the check mark there.
Click the +Add IP Range button. The Add IP Range page opens..

In the Start field, enter the IP address that defines the beginning of the range.
In the End field, enter the IP address that defines the end of the range.

NOTE: To locate a single printer, enter that printer’s IP address in the Start and End fields.

If you do not want the address range activated in the next printer discovery, remove the check mark after Enabled. Otherwise, leave the check mark there.
Enter a Description of the range.
Click OK on the Add IP Range window. The Printer Discovery window opens again.
If you want to add another IP address range, go back to step 3.

After you add IP address ranges, the Printer Discovery window shows the following information:

Printer Dicovery Page
Information	Definition
SNMP broadcast	A check mark appears in front of Use SNMP broadcast if it is enabled.
Start	The lower limit of the IP address range.
End	The upper limit of the IP address range
Enabled	This column display Yes if the IP range is enabled.
Description	The description that was entered for the IP address range.

To change disable or remove an address range:

Click on the appropriate row and select the action from the drop-down list.

NOTE: To take a single action on several address ranges, click the box in front of each address range you want to remove or disable. Click on one of the rows and select the action from the drop-down list.
