If we go back to the code you showed us in post #1 in this thread:
you will see two lines that I have highlighted in red. According to the standards, these two lines tell the script to split the 1st argument given to the functions ip2dec() and sanitize() into an array named slice with every character in the 1st argument to be treated as a field separator (in other words, the "." argument to split() is an extended regular expression that is a special character matching any character and if those functions are called with an argument like "192.168.0.15" you'll end up with the slice array having 13 elements each with a value that is an empty string; not 4 elements having the values 192, 168, 0, and 15, respectively, that I assume your code is expecting).
Please try rerunning your script after changing those two lines to any one of the following four possible replacements:
and let us know what happens.
Dear Srs :-)
I'm looking for a shell script, that given a network in CIDR format it lists all IPs, for example:
Preferredly a shell script, but a Perl, Python, C, etc.. is also welcome :-)
I have been looking in sipcalc, ipcalc, etc.. options but this feature is not implemented :-(

Hello everybody,
I'm coding a network program and i need it to "understand" ip ranges, but i don't know how to make to parse an IP CIDR range, let's say "172.16.10.0/24" to work with the specified IP range.
I've found a program which does it, but i don't understand the code. Here is the... (3 Replies)
I have a list of about 200,000 lines in a text file that look like this:
1 1 120
1 80 200
1 150 270
5 50 170
5 100 220
5 300 420
The first column is an identifier, the next 2 columns are a range (always 120 value range)
I'm trying fill in the values of those ranges, and remove... (4 Replies)
Hi,
I have two files
file1 chr1_22450_22500
chr2_12300_12350
chr1_34500_34550
file2 11000_13000
15000_19000
33000_44000
If the file 1 ranges fall between file2 ranges then assign the value of file2 in column 2 to file1
output:
chr2_12300_12350 11000_13000
chr1_34500_34550 ... (7 Replies)
Looking for a simple way to convert ranges to a numerical sequence that would assign the original value of the range to the individual numbers that are on the range.

Hi all, I would appreciate if someone could share how to convert CIDR notation to netmask and vice versa.
The value below is just an example. it could be different numbers/ip addresses.
Initial Output, let say file1.txt
Final Output, let say file2.txt (3 Replies)
Hi,
Recently I had to convert a 280K lines of ip ranges to the CIDR notation and generate a file to be used by ipset (netfilter) for ip filtering.
Input file:
000.000.000.000 - 000.255.255.255 , 000 , invalid ip
001.000.064.000 - 001.000.127.255 , 000 , XXXXX

Weary of seeing our load average go up to 50+, I just did a major block on these networks (stats over a less than 20 min interval):
