Need help configuring apache with 3 different hostnames that support wildcard subdomains

Question

I have a single physical server. I need to set it up so i can have 3 different domains on it. Each one of these domains needs to be able to support wildcard sub-domains. (.example.com,.example2.com,*.example3.com) I can purchase two more ips if this will make things easier.

The current setup is as follows

www.example.com => default vhost

devel.example.com => development server this is the only server that currently accepts *.example.com

staging.example.com => only works via staging.example.com

essentially i need all of these different to accept a wild card subdomain which i why i believe i need separate domain names for each.

What is the best way to get this all setup?

Thanks in advance.

You can create the wildcard domain up via DNS. For each domain that will be different, however, you will need to create a subdomain for it via DNS. Setup the Apache configuration using the ServerAlias and ServerName for your main subdomain and ServerAlias for your subdomains:

<VirtualHost IP:80>
    ServerAdmin root@localhost
    ServerName www.example.com
    ServerAlias example.com
</VirtualHost>

<VirtualHost IP:80>
    ServerAdmin root@localhost
    ServerAlias devel.example.com
</VirtualHost>

<VirtualHost IP:80>
    ServerAdmin root@localhost
    ServerAlias staging.example.com
</VirtualHost>

You could use .htaccess to do the same thing I believe, but I like doing it this way better - personal preference.
