subnet_splitter

This utility will help you splitting your big subnets in smaller ones.

Instructions

The script takes as inputs:

• a file with a list of subnets (-i --input)
• a number that represents the subnet dimension you want to obtain (-s --size)
• an output file (-o --output)

Input file example:

$ cat /tmp/input_big.txt
217.141.57.208/29
195.103.115.74/32 
193.108.60.0/22 
82.112.223.136/32

Program execution example:

$ python3 subnet_splitter.py -i /tmp/input_big.txt -o /tmp/output.txt -s 26

Output example:

cat /tmp/output.txt 
217.141.57.208/29 
195.103.115.74/32 
193.108.60.0/26
