$3

``js
require('sock-share') // hacks dgram

var dgram = require('dgram')

var a = dgram.createSocket('udp4')
var b = dgram.createSocket('udp4')
var c = dgram.createSocket('udp4')

a.bind(12345)
b.bind(12345)
c.bind(54321)

a.on('message', logger('a'))
b.on('message', logger('b'))
c.send(new Buffer('hey'), 0, 3, 12345, '127.0.0.1')

// -> a hey
// -> b hey
// with regular dgram.Socket, either a or b would get the message, but not both

function logger (name) {
return function (msg) {
console.log(name, msg.toString())
}
}
`

$3

`js
var a = dgram.createSocket('udp4')
a.filterMessages(function (msg, rinfo) {
return /^d1:.?d2:id20:/.test(msg) // only accept bittorrent-dht messages
})

a.on('message', function (msg, rinfo) {
// msg is a bittorrent-dht message
})
