You're probably right.
But my point covered only the fact that if a method needs something it
should ask it explicitly throught parameters, not taking the opportunity
to guess it since it happens that it's a xmlrpc server and that the
information could be deduced from the client IP address.
My feeling is that the OP needed something else than the client IP
address, and was trying at the server side to map client IPs with the
data he effectively needs. I could be wrong though.
