orange-ip v0.1.0

Orange IP

Library for working with IP addresses.

Example

Let's say we have some config with whitelisted sub networks / IP addresses and we want to see if user's IP is whitelisted.

Actually there is a method OrangeIPv4Subnet.isIpInOneOfTheSubnets, but let's pretend we don't have it :)

const {OrangeIPv4Subnet} = require("orange-ip")

const WHITELISTED = "10.0.0.0/8;45.55.52.131".split(';').map(v => new OrangeIPv4Subnet(v))

function is_whitelisted(ip) {
  for (const s of WHITELISTED) {
    if (s.isIpInTheSubnet(ip)) return true
  }
  return false
}

console.log(is_whitelisted("45.55.52.131")) // true
console.log(is_whitelisted("10.10.10.10")) // true
console.log(is_whitelisted("8.8.8.8")) // false
