vgersh99 the sample I provided had a hyphen between the IP address ranges and the one you provided has a space for a field separator. Thank you for addressing the issue though, since I also noticed that when a hyphen was used as a field separator for a single IP address range the output wasn't being appended with /32. I've refined the code and removed the bit_or(), bit_lshift () and bit_rshift () functions since they were much slower than using gawk's built in or(), lshift() and rshift() functions. Can't use mawk now but the code below is still faster now using gawk. For some reason I get a segmentation fault with awk.
Here are benchmarks processing a file containing ip address ranges. The output file after running the script contained 236,315 lines.
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.
Thank you

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
