#IP-Subnet

This is a cli tool that performs common operations on IP addresses and associated subnet masks.

# Set up
For Unix/Linux systems
Ensure you have Python3+ installed

git clone
Open run.sh and modify `/your/path` to your's
Run `run.sh`

Change directory to the project folder.
Make `ip_subnet.py` file executable by doing:
`sudo chmod +x ip_subnet.py`

# Usage
usage: ip_subnet.py [-h]
                    [-i IP_AND_SUBNETMASK IP_AND_SUBNETMASK | -c NETWORK_PREFIX | --version]
                    [--create-subnets CREATE_SUBNETS] [--create-hosts CREATE_HOSTS]
                    
optional arguments:
  -h, --help            show this help message and exit
  -i IP_AND_SUBNETMASK IP_AND_SUBNETMASK
                        Accepts an ip adress with subnet mask in subnet
                        notation ./ip_subnet -i 255.255.255.0
  -c NETWORK_PREFIX
                        Accepts subnet mask in network prefix notation. i.e
                        ./ip_subnet -c192.168.0.22/24
  --create-subnets
  --create-hosts 
  --version             show program's version number and exit

Usage 1: Retrieving total number of IP addresses in a subnet mask
  Using CIDR notation: ./ip_subnet.py -c 192.68.73.1/232
  Using Decimal notation: ./ip_subnet.py -i 192.168.73.1 255.255.255.0
  
Usage 2: Create N subnets or hosts.
  NB: Ensure that N is a power of 2 within 0-255. e.g, 2, 4, 8... I'm trusting you to input correct N
      Subnets and hosts can only be created by inputing the address and masks in CIDR. Support for decimal should come soon.
      
      ./ip_subnet.py --create-subnets 8 -c 192.68.73.1/24
      ./ip_subnet.py --create-hosts 128 -c 140.25.0.0/16

Other things to note:
Network Prefix is same as CIDR (Classless Inter-Domain Range)
