Apache Multiple Sites: Show different site to visitors on domain-name than to IP address?

Question

I want to set up my server for multiple sites but I want a good error message if people try to access them by the IP, is there any way to set this up in httpd.conf? I know you have to use virtualhosts but everything wants a servername and everywhere I've seen that's been set to a domain, is there any way to set servername to an IP to serve alternate content?

Answer 1

As it goes in Apache docs, the first defined virtual host becomes primary and serves the requests that doesn't match any other virtualhost's ServerName (also, there are many useful examples of different configurations)
