Set back the first IP

I  installed VMWare for the first time and the IP was set to x.x.x.x Due to some issues I had to uninstall and reinstall it. After reinstallation IP is set to x.x.y.x. But I don't want this IP address I want to set it back to x.x.x.x

Please help me how can I set IP back.

Hope I get the solution here.

Thanks,
