OSC sender IP address



I am working on a project, where the remote needs to send back data via OSC to the sender. Thus, is it possible to find out, which IP address was used to send the OSC message? Actually, only the remote needs to know it. Thus, I either need to find out the address of the interface that is used by OSCsender or I need to find out the IP address where the OSCmessage came from on receiver side. Does anyone have an idea?
