📄 Description

I was using WILDCARD to create the DatagramSocket new DatagramSocket(port) but was getting issues, by some reason the dns clients like nslookup wasn't able the get the responses when querying using a virtual network interface like docker, when querying using the real interfaces or 127.0.0.1 it worked.

Solution was to start one UDP server for every interface this way all worked
