Usage

import { ipv4 } from 'ip-address-utils';

ipv4.isValid('192.168.1.0'); // true
ipv4.isSubnet('192.168.1.0/24'); // true
ipv4.isIpHost('192.168.1.0'); // true
ipv4.isValidIpRange('0.0.0.1-192.168.1.191', {
  subnet: '192.168.1.134/26'
}); // false
ipv4.toBuffer('192.168.0.1'); // new Buffer([192.168.0.1])
ipv4.fromBuffer(new Buffer([192, 168, 0, 1])); // '192.168.0.1'
ipv4.toBitmask('255.255.0.0'); // 16
ipv4.fromBitmask(16); //'255.255.0.0'
ipv4.toDecimal('192.168.0.1'); // 3232235521
ipv4.fromDecimal(3232235521); // '192.168.0.1'
ipv4.subnet('192.168.0.1/26');
// {
//   bitmask: 26,
//   netmask: '255.255.255.192',
//   hostCount: 62,
//   networkAddress: '192.168.0.0',
//   broadcastAddress: '192.168.0.63',
