Subnet IP Address Calculator

subnet ip calculator in c++

Version: 0.3.0

With this calculator you can calculate subnet IP address by getting one of existing subnet IP host addresses.

1. installation

• to install it you will need to clone git:

$ git clone https://github.com/jakkundev/ipcalc.git

• after cloning it you will need to move to it's directory:

$ cd ipcalc

• after moving there you can finally use makefile (remember to use sudo while performing it):

$ sudo make all

after done with that, ipcalc has been successfuly added to your linux machine commands

2. Syntax of this is:

$ ipcalc [OPTION]

3. or:

$ ipcalc [IP] [MASK]

4. for the moment being there's only six options:

-h or --help                     Displays info about available options
                                  and version of software.
-i or --ip[=IP]                  You can input ip address after it
-m or --mask[=MASK]              You can input mask address after it
-b or --calculate-bin[=BIN]      Calculates binary mask/ip address 
                                  from passed decimal mask/ip address
-d or --calculate-dec[=DEC]      Calculates decimal mask/ip address
                                  from passed binary mask/ip address
-n or --get-new-mask[=AMOUNT]    Outputs how many 1's you have to swap
                                  with 0's in binary mask address and
                                  amount of subnets.
-a or --all[=IP][=MASK]          Displays info about all available subnets.
-v or --version                  Outputs software version in terminal.

5. example of usage (with output):

$ ipcalc -b 192.168.1.0
11000000.10101000.00000001.00000000

$ ipcalc -d 11000000.10101000.00000001.00000000
192.168.1.0

$ ipcalc -n 10
You will need to swap: 4 '0' in mask
amount of subnets will be: 16
