Is there any way to get array (toArray) or traverse (forEach) of ip addresses from Range?

[nodkz]

For example:

const myRange = new Ip.Range('10.0.0.1', '10.0.0.5');
myRange.toArray(); // ['10.0.0.1', '10.0.0.2', '10.0.0.3', '10.0.0.4', '10.0.0.5']
myRange.forEach((ip) => { console.log(ip) }); // 5 times output ip adresses to console

@nodkz you could achieve that by iterating through the IPs as numbers, for instance:

const myRange = new Ip.Range('10.0.0.1', '10.0.0.5');
for (let ip = myRange.firstIp().toNum(), lastIp = myRange.lastIp().toNum(); ip <= lastIp; ip++) {
  console.log(new Ip.Addr(ip).toString());
}

toArray & forEach helper methods will be very appreciated 🙏

In such case, we may forget about such packages like

• https://www.npmjs.com/package/ip-cidr
• https://www.npmjs.com/package/ip-from-range
• https://www.npmjs.com/package/cidr-range

You can have it easily by using the iteration mentioned above:

function toArray(range) {
  const result = [];
  for (let ip = range.firstIp().toNum(), lastIp = range.lastIp().toNum(); ip <= lastIp; ip++) {
    result.push(new Ip.Addr(ip));
  }
  return result;
}

Because this is a rather specific use case, for the sake of keeping API simplicity and because it's relatively easy to transform externally, I'd rather not include it as an internal method.

I disagree with you. These methods are greatly simplifying work with ranges. And writing them manually is quite tedious.
