Wildcard DNS for Wordpress MU

[fufamily]

Hi, I've installed Wordpress MU and the README (http://trac.mu.wordpress.org/browser/trunk/README.txt) says I need to have a wildcard DNS entry for it to work.

Can an administrator do that for me?

I believe my case is similar to this previous poster:

My details are

Username: fufamily
Domain: fufamily.com
Hosting package: Ad-Enhanced Advanced

Thanks,

FF.
