I'm not sure what you mean by "change the IP configuration for IPV4" but if "on wire" means an ethernet card then the simplest way I do these changes is to log in as root in a terminal, navigate to:

though, as I understand it, this file is a little out of date which means that the very latest is in the source code, but I've never had to go there for my simple and ordinary purposes.
