Extraction of ip used from client and service

[sterfrag]

I have created a client that makes appropriate requests and uses a config.json file with an Ip defined in unicast.
My question is if there is a way, other than the print messages, to extract the info programmatically of what is the ip used when the object of client is constructed. In the code, this info resides in routing_manager_impl.cpp file and I would like to know how I can access that.
My goal is to check whether my software uses the correct ip.
