Where does http://<domain>.com redirect to?

Hello,

I am encountering something quite strange.

We have a domain, lets say xyz.com.

This domain works fine when you type in http://www.xyz.com in a browser (i.e. the correct website is served up). However, when you type in http://xyz.com it goes somewhere completely different, although related.

I know that you create subdomains by using the format http://subdomain.xyz.com, and that you define these in your DNS and Apache configs. But what I don't understand is, is there some kind of generic subdomain that is used (when no subdomain or www. is present)?

As when http://xyz.com is typed in, it goes to a closely related site hosted on the same server. I don't control the DNS but do control the webserver, so I am assuming that this is a DNS issue... Am I right?

Thanks

Since you don't control the DNS, this is then entirely some issues with Apache. If you want http://xyz.com to be the same site as http://www.xyz.com (default), then add ServerAlias like so:

<VirtualHost *>
ServerName www.xyz.com
ServerAlias xyz.com
DocumentRoot /var/html/htdocs
....
....
</VirtualHost>

>> is there some kind of generic subdomain that is used

It's all personal preference. If you are wondering what subdomain is available, ask your host.
