From this information, we can formulate the following IP address ranges and import them into
HP Web Jetadmin:
15.0.1.1 - 15.0.1.254
15.0.2.1 - 15.0.2.254
15.0.3.1 - 15.0.3.254
15.0.4.1 - 15.0.4.254
15.0.5.1 - 15.0.5.254
15.0.30.1 - 15.0.30.254
15.0.31.1 - 15.0.31.254
15.0.32.1 - 15.0.32.254
15.0.33.1 - 15.0.33.254
15.0.34.1 - 15.0.34.254
15.0.35.1 - 15.0.35.254
15.0.36.1 - 15.0.36.254
15.0.37.1 - 15.0.37.254
15.0.1.1 - 15.0.1.254
15.0.2.1 - 15.0.2.254
15.0.3.1 - 15.0.3.254
15.0.4.1 - 15.0.4.254
15.0.5.1 - 15.0.5.254
15.0.30.1 - 15.0.30.254
15.0.31.1 - 15.0.31.254
15.0.32.1 - 15.0.32.254
15.0.33.1 - 15.0.33.254
15.0.34.1 - 15.0.34.254
15.0.35.1 - 15.0.35.254
15.0.36.1 - 15.0.36.254
We can take the formulation one step further and simplify things. Some of our IP ranges are
contiguous and in order, making it easy to combine them. The final result looks like this:
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
We have reduced the number of IP ranges to four. We can convert this to a form that is easily
imported into HP Web Jetadmin via a text file and also reflects descriptions:
15.0.1.1-15.0.5.254 = subnet range for western region
15.0.30.1-15.0.39.254 = subnet range for central region
15.0.55.1-15.0.55.254 = subnet range for branch office
15.0.64.1-15.0. 74.254 = subnet range for eastern region
Of course, leaving the 20 ranges as separate items would also work. Consolidating ranges makes
dealing with large quantities of data simpler, but may not help when descriptions are needed for the
purpose of cataloging ranges.
IP range files—Import and export features
IP range data can be developed in other applications and imported as text files. HP Web Jetadmin
can also export IP range data to text files. This makes it easier to deal with large numbers of IP
ranges, manipulate complex data and archive data for use in multiple instances. Let’s break down the
file format for IP range import/export:
Characteristics of IP range files:
One range per line.
Each IP address is separated by a hyphen (-).
Comment or description strings can be appended to the IP range by using an equal sign (=).
Example of one IP range with a comment (where xxx represents an octet in the IP address):
xxx.xxx.xxx.xxx-xxx.xxx.xxx.xxx=descriptive text string
