Calculator for IPv4 networks
npm install ipv4-calculator
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$3
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
