IP Calculator Tool

The IP Calculator is a command-line tool written in Golang that assists in managing IPv4 addresses, subnetting, IPv6 shortening, and various networking operations.

Features

• IPv4 Operations:

  • Calculate network details such as network address, broadcast address, and available hosts within a subnet.
  • Validate IPv4 addresses.
  • Perform subnetting calculations.
  • Perform route summarization calculations.

• IPv6 Operations:

  • Shorten IPv6 addresses using the compressed representation.
  • Extract and display IPv6 information like network prefix, interface ID, etc.

Installation

Make sure you have Go installed. Clone the repository and build the tool:

git clone https://github.com/iLaurian/ip-calculator.git
cd ip-calculator
go build

Alternatively, build using Nix:

nix build github:ilaurian/ip-calculator
nix run github:ilaurian/ip-calculator

# or
git clone https://github.com/iLaurian/ip-calculator.git
nix build .

Usage

Run the ip-calculator executable with appropriate command-line arguments to utilize different functionalities:

Example

Get help

./ip-calculator -h
./ip-calculator --help

IPv4 Information

./ip-calculator -ipv4 192.168.0.0/24 --info

IPv4 Route Summarization

./ip-calculator --summary-route 10.10.0.0,10.20.0.0,10.30.0.0,10.40.0.0

IPv4 VLSM Subnetting

./ip-calculator --ipv4=10.10.0.0/16 --vlsm 10,20,30,40

NOTE: The number of hosts should not include the broadcast and the network address.

IPv6 Information

./ip-calculator --ipv6=2001:0db8::1/64 --info

IPv6 Shortening

./ip-calculator -ipv6 2001:0db8:0000:0000:0000:0000:0000:0001/64 --compress

Command line flag syntax

The following forms are permitted:

-flag
--flag   // double dashes are also permitted
-flag=x
-flag x  // non-boolean flags only
