如何使用Node.JS从IPv6池中随机选择传出地址？

Question

I'm trying to create and run a Node.JS proxy in a machine that has a pool of IPv6 addresses. I want the proxy to randomly choose one of these addresses for each request (making it difficult for the websites to track record of users' requests).

With wget I can achieve this by using the attribute --bind-address as following:

wget --bind-address OUTGOING_IP http://www.example.com/

Is there any way to achieve the same behavior using Node.JS?

If you want to make outbound HTTP requests from different IPs, have a look for "localAddress" option under "http.request":

If you want to start a TCP server to listen on a particular IP bound to your host, you would probably want to specify it when you create the server [ie server.listen(PORT, HOST)]:
