15.0.1.1-15.0.5.254
●
15.0.30.1-15.0.39.254
●
15.0.55.1-15.0.55.254

15.0.64.1-15.0.74.254
This has reduced the number of IP ranges from 27 to 4. We can build this into a form that is easily imported into
HP Web Jetadmin and also reects descriptions. Here is an example of data that can be imported via a text le:
●
15.0.1.1-15.0.5.254 = subnet range for western area
●
15.0.30.1-15.0.39.254 = subnet range for central area
●
15.0.55.1-15.0.55.254 = subnet range for branch oce
●
15.0.64.1-15.0.74.254 = subnet range for eastern area
Consolidating ranges makes dealing with large quantities of data simpler but may not help when descriptions
are needed for the purpose of cataloging ranges.
Import and Export Features of IP Range Files
IP range data can be developed in other tools and imported through text les. In fact, HP Web Jetadmin can
export IP range data to text les. This makes it easier to deal with large numbers of IP ranges, manipulate
complex data and archive data for use in multiple instances. Tile format for IP Range import and export le
format can be broken down as follows:
●
1 range per line
●
Each IP address is separated by a hyphen character (-)
●
Comment or description strings can be appended to the IP range by using an equal character (=)
Here is an example of 1 IP range with a comment: xxx.xxx.xxx.xxx-xxx.xxx.xxx.xxx=descriptive text string
(where xxx represents an octet in the IP address).
There is no known limit to the number of IP ranges manageable within HP Web Jetadmin software. IP ranges are
also used by other features like PC-Connected printer discovery and HP Web Jetadmin Installations discovery. All
IP ranges entered into HP Web Jetadmin can also be managed globally from within Tools > Options > Shared >
Discovery > Methods > IP Range > IP Ranges.
IP Range Discoveries for Network Devices
IP Range discoveries for network devices or HP Web Jetadmin installations rst send an SNMP query to all
addresses within the range. When nodes are discovered, HP Web Jetadmin performs queries to determine
qualied devices. These qualied devices, when found, are added to the device lists.
Characteristics of IP range discoveries for network devices or HP Web Jetadmin installations include:
●
IP ranges are simply two addresses that represent range begin and end points.
●
Multiple ranges can be specied in an IP Range discovery.
●
IP range data can be manually added through the user interface.
●
IP ranges can be imported to HP Web Jetadmin from text les.
●
Multiple IP ranges can be added and with optional, descriptive tags.
