IP tries (prefix tree)
npm install iptrie-node8IP address trie implementation.
1. Run node-gyp configure build.
2. Test node test/t.js.
An example:
var iptrie = require('iptrie'),
lookup = new iptrie.IPTrie();
lookup.add("10.0.0.0", 8, 'rfc1918');
lookup.add("10.80.116.0", 23, 'my little bit of the world');
var expectnull = lookup.find("1.2.3.4"); # is null
var otherplace = lookup.find("10.10.2.2"); # not mine
var myplace = lookup.find("10.80.117.4"); # mine
Add a route to ipaddress/prefix and attach the provided value to it.
Remove the route ipaddress/prefix returning true/false based on success.
Find the data attached to the route that best fits the provided
ipaddress. This will use "BPM" biggest prefix matching just as typical
routing policies dictate.
