Exactly. But this only happens for any subdomains that aren't
registered in my DNS. Obviously, I can put anyhost.mydomain.net into my DNS, but then any other sub domains that aren't registered. I can't add every single possibility to my DNS. For example:
resolves a site
ww.mydomain.tld resolves the shared IP page.
w.mydomain.tld resolves the shared IP page.
anythingelse.mydomain.tld resolves the shared IP page.
Do you see what I mean? What I'd like is for those domains to show the "Page cannot be displayed" page in the browser. Just like you get if you went to http://randomsubdomain.google.com
