IP Address Set

Efficient mutable set data structure optimized for use with IPv4 and IPv6 addresses. The primary use case is for working with potentially large IP blacklists.

Works in the browser with browserify! This module is used by WebTorrent.

install

npm install ip-set

usage

const IPSet = require('ip-set')
 
const ipSet = new IPSet(/* optionally pass an array of IP addresses to seed the set with */)
ipSet.add(exampleBlockedIP1)
ipSet.add(exampleBlockedIP2)
let isBlocked = ipSet.contains(exampleBlockedIP2) // isBlocked will be true

CIDR ip's are also supported

ipSet.add(`192.168.1.0/24`);
let isBlockedInList = ipSet.contains('192.168.1.0');// isBlockedInList will be true
isBlockedInList = ipSet.contains('192.168.1.255');// isBlockedInList will be true

todo

(prioritized highest to lowest)

  • Port IPv4 implementation from torrent-stream
  • Add basic tests
  • Support CIDR notation
