The domain name http://fc7777.coffeecup.com/ remains the same, but I can use it for testing any number of websites. The domain name is not part of the working of a website, but rather the place where the website files happen to be put. Nearly all the files of the website http://www.clparker.com used to reside at http://fc7777.coffeecup.com/ as previously did the files of an older version of http://www.clparker.com.

The above is, of course, subject to using relative addressing, rather than absolute addressing, within the website. There is an article about such addressing here.

PS. The last couple of sentences of the article about relative addressing are particularly pertinent.
