IP tries (prefix tree)
IP address trie implementation.
node-waf configure build.
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("18.104.22.168"); # 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.
