How to run nodeJS with different IP on the same server?

Question

Computer networks

There is a server (for example VPS) which has several IP addresses. You need to run 2 nodejs scripts with different IPs, and you can’t specify this separately in some module, you need to somehow externally. Maybe in some kind of sandbox, or something else?

Answer 1

If the server has multiple IPs, then make listen on 0.0.0.0 or don't specify the second listen parameter at all: server.listen(80)

Answer 2

https://nodejs.org/api/http.html#http_server_liste...

HttpServer.listen(80, 8.8.8.8);
HttpServer.listen(80, 9.9.9.9);

Answer 3

1) try to change the IP as in the first tip
2) try to change the port and use an external balancer
3) run in a virtual environment (for example, docker)
