Welcome to WebmasterWorld Guest from 188.8.131.52
I have to move about half a dozen sites due to poor hosting support to a new and improved hosting service.
Since I buy my domain names elsewhere and control the names servers in use myself, all I have to do is update this to the new location. This much I can figure out.
What I don't know, is whether Google will react negatively to my IP address changing. I also monetize these sites through AdSense so there is that to worry about as well.
