    IPv4 networks calculator

    Get IPs list for any network, first network IP address and broadcast IP address.

    Installation

    npm install ipv4-calculator --save
    

    Usage

    import * as ipCalculator from 'ipv4-calculator';
    
    ipCalculator.getNetworkFirstIp('192.210.0.11/30'); // '192.210.0.8'
    ipCalculator.getNetworkFirstIpAsArray('192.210.0.11/30'); // [192, 210, 0, 8]
    ipCalculator.getNetworkBroadcastIp('192.210.0.25/28'); // '192.210.0.31'
    ipCalculator.getNetworkBroadcastIpAsArray('192.210.0.25/28'); // [192, 210, 0, 31]
    ipCalculator.getNetworkIps('192.210.0.25/30'); // ['192.210.0.24', '192.210.0.25', '192.210.0.26', '192.210.0.27']
    ipCalculator.getNetworkIpsQuantity('192.210.0.25/30'); // 4
    ipCalculator.getNetworkIpsQuantityByMask(30); // 4

    You are able to use utils, validators and decorators from this package

    Utils

    import * as utils from 'ipv4-calculator/dist/utils';
    
    utils.numberToBinaryString(2); // '10'
    utils.binaryStringToNumber('10'); // 2
    
    utils.ipToBinaryString('192.168.0.29'); // '11000000101010000000000000011101'
    utils.binaryStringToIp('11000000101010000000000000011101'); // '192.168.0.29'
    
    utils.ipToNumber('192.168.0.29'); // 3232235549
    utils.ipNumberToIp(3232235549); // '192.168.0.29'
    
    utils.ipNumberToBinaryString(3232235549); // '11000000101010000000000000011101'
    
    utils.maskToBinaryString(31); // '11111111111111111111111111111110'
    utils.binaryStringToMask('11111111111111111111111111111110'); // 31
    

    Validators

    import * as validator from 'ipv4-calculator/dist/validators';
    
    validator.isMaskValid(15); // true
    validator.isMaskValid(150); // false
    
    validator.isIpValid('192.169.0.10'); // true
    validator.isIpValid('0.0.0.256'); // false
    
    validator.isIpNumberValid(4294967295); // true
    validator.isIpNumberValid(4294967295 + 1); // false
    
    validator.isBinaryStringValid('01010101010101010101010101010101'); // true
    validator.isBinaryStringValid('22'); // false
    
    validator.isBinaryMaskValid('11111111111111100000000000000000'); // true
    validator.isBinaryMaskValid('11111111111111100000000000000001'); // false
    
    validator.isNetworkValid('0.0.0.0/0'); // true
    validator.isNetworkValid('0.0.0.0/33'); // false
    

    Decorators

    import * as decorators from 'ipv4-calculator/dist/decorators';
    
    class SomeClass {
      @decorators.validateMaskDecorator // throw Error if mask is invalid
      doSomethingWithNetworkMask(mask) {
        // ...
      }
    
      @decorators.validateIpDecorator // throw Error if IP is invalid
      doSomethingWithIpAddress(ip) {
        // ...
      }
    
      @decorators.validateNetworkAddressDecorator // throw Error if network is invalid
      doSomethingWithIpNetwork(network) {
        // ...
      }
    
      @decorators.validateBinaryStringDecorator // throw Error if binary string is invalid
      doSomethingWithBinaryString(string) {
        // ...
      }
    
      @decorators.validateBinaryMaskDecorator  // throw Error if binary mask is invalid
      doSomethingWithBinaryMask(mask) {
        // ...
      }
    
      @decorators.validateIpNumberDecorator // throw Error if IP number is invalid
      doSomethingWithIpNumber(ipNumber) {
        // ...
      }
    }
    
    // or use decorate util to decorate any function
    const myFunc = decorators.decorate(ip => {
      // only if IP valid
      // in other case Error will be throwed
    }, decorators.validateIpDecorator);
