I found it weird that some domains were using characters besides numbers, letters, and dashes in their domain. How is this possible?? I thought domains were limited to numbers, letters, & dashes. i saw a site (http://www.ll.com) uses both these domains to redirect to their site. Is somethign wrong with my browser? i just randomly typed in these domains just to play around but it actually redirected to another site.

www.b@ll.com (http://www.b@ll.com/)
www.b@seball.com (http://www.baseb@ll.com/)

It's another case of the things that were talked about in another thread today
