http://www not working

[hemanthjava]

I have a site dedicated to Rey Mysterio.

The Site URL is Rey Mysterio Highlights

But when I type Rey Mysterio Highlights, It sometimes give me page not found. Why is this error when I add that extra www. Is there a solution to this probelm

This is a DNS issue. Some DNS servers cannot forward or locate without the "www" in front or the URL. This can be solved if your DNS or forwarder supports "Reverse Lookups". Ask your administrator if they offer this feature.
