Top Forums Shell Programming and Scripting Convert ip ranges to CIDR netblock Post 303027639 by azdps on Friday 21st of December 2018 06:23:18 AM

I tested the new script with these test IP ranges and it didn't correctly convert the IP ranges to CIDR blocks so I initially thought it wasn't working correctly. The script does not work with this specific field separator " - ":
Code:
1.62.189.215 - 1.62.189.222
4.0.25.146 - 4.0.25.148
4.0.26.14 - 4.0.29.24
24.149.30.0 - 24.149.30.4

Edit:

I removed the space between the IP address range from the test IP ranges and the script correctly converted the the IP ranges.
Code:
1.62.189.215-1.62.189.222
4.0.25.146-4.0.25.148
4.0.26.14-4.0.29.24
24.149.30.0-24.149.30.4

I also copied the test IP ranges directly from the downloaded file in question without any changes to each line and it converts properly.

Code:
# List distributed by iblocklist.com

botnet on China Unicom Heilongjiang:1.62.189.215-1.62.189.222
s0-0.ciscoseattle.bbnplanet.net:4.0.25.146-4.0.25.148
p1-0.cisco.bbnplanet.net:4.0.26.14-4.0.29.24
CEDAR FALLS UTILITIES:24.149.30.0-24.149.30.4

I added space hyphen space to the field separators and it converts my first test IP range correctly.
Code:
BEGIN{
        FS="-| - |:"
}

Thank you! The script works absolutely great! I compared the script results against ipcalc results and they were exactly the same.

NAME
Locale::Script - standard codes for script identification SYNOPSIS
use Locale::Script; $script = code2script('phnx'); # 'Phoenician' $code = script2code('Phoenician'); # 'Phnx' $code = script2code('Phoenician', LOCALE_CODE_NUMERIC); # 115 @codes = all_script_codes(); @scripts = all_script_names(); DESCRIPTION
The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924 four-letter codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying scripts. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $script = code2script('phnx','alpha'); $script = code2script('phnx',LOCALE_SCRIPT_ALPHA); The codesets currently supported are: alpha, LOCALE_SCRIPT_ALPHA This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician. It also includes additions to this set included in the IANA language registry. The Zxxx, Zyyy, and Zzzz codes are not used. This is the default code set. num, LOCALE_SCRIPT_NUMERIC This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician. ROUTINES
