I need bash code to generate a RANGE of given IP addresses.
For example if I have the following simple list:
1.1.1.1
1.1.1.2
1.1.1.3
1.1.1.5
1.1.2.1
1.2.3.4
100.100.1.2
100.100.1.3
My output will be:
(1.1.1.1-1.1.1.3)
1.1.1.5
1.1.2.1
1.2.3.4
(100.100.1.2-100.100.1.3)
...and so on.
ONLY nearest IPS will included in RANGE.

While it is certainly possible to write this in bash, covering all the corner cases is quite hard. Can you install a special-purpose tool for this task, like iprange?
iprange -j output is very close to what you need, and you can eliminate the singleton ranges like this:
iprange -j | sed 's/^(.*)-1$/1/'

Effectively it is a functional program which converts a sorted list of IP addresses to your range format. Funny IP addresses with leading 0's or unsorted lists are not handled in this simple example (but could be with gmtt onboard functions).
