Setting -ip on a server has no effect. Hence writing out the IP is irrelevant; The IP will be the lowest addy it finds on the machine. Hence if you have a 192 addy, it will always be that one.
Put another way, suppose you had a 168 addy on the same box as the 192. Even if you wrote the 192 addy explicitly (as you have above), 3DGS will still AFAIK assign the server the 168 addy.
So to answer your question, the above and the below...
