Why is init listening on port 14500 on ubuntu 18.10

I am running Ubuntu 18.10, up to date as of now. I see init listening on port 14500. This does not change after a reboot. I don’t recall ever seeing this before. Here is the relevant line from “sudo netstat -anp” output. Can anyone help me understand what this is?

    tcp6       0      0 :::14500                :::*                    LISTEN      1/init               

My web searching didn’t turn up any reason for this, so I’m asking here.
