It shouldn't be that hard to find out.   Monitor an infected machine and sniff the ethernet traffic and see what it tries to connect to.   note the host IP,  then look in the code and see the relationship,  perhaps it might even lead to a function it derives to get the REAL one.   Just a thought....
