load-ip-set v3.0.1
load-ip-set

download and parse ip-set (blocklist) files
This module is used by WebTorrent!
Install
npm install load-ip-set
Usage
Given one of the following:
- http/https url (gzip, deflate, or no compression)
- filesystem path (gzip, or no compression)
- array of ip addresses or
{ start: '1.2.3.0', end: '1.2.3.255' }
ip ranges
this module loads the ip set (downloading from the network, if necessary) and returns an ip-set object. An ip-set
is just a mutable set data structure optimized for use with IPv4 and IPv6 addresses.
import loadIPSet from 'load-ip-set'
loadIPSet('http://example.com/list.txt', (err, ipSet) => {
if (err) throw err
ipSet.contains('1.2.3.4') //=> true
ipSet.contains('2.2.2.2') //=> false
})
The second argument can be an optional opts
object which will be passed to
simple-get
and the node.js core http.request
method. This is useful for setting the user agent, for example.
loadIPSet('http://example.com/list.txt', {
headers: {
'user-agent': 'WebTorrent (http://webtorrent.io)'
}
}, (err, ipSet) => {
})
