chromium browser (pepperflashplugin) opening listening ports on 0.0.0.0:5353

I am using chromium browser (chrome) with pepperflashplugin in Debian. I have noticed, chromium/pepperflashplugin opens a listening port on my public interface 0.0.0.0:5353 as seen with netstat: netstat -lptun Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name udp 0 0 0.0.0.0:5353 0.0.0.0:* 13971/libpepflashpl I have been using Firefox (Iceweasel) before and I have never seen browser/flash-plugin to open ports. Indeed, I have never seen any client application opening listening ports on 0.0.0.0. **Why is chromium doing this?** **Is this necessary ?** **Can I disable this?** **Can I start chromium with pepperflashplugin disabled ?**
