Apache default VirtualHost

Question

how can I set a default VirtualHost in apache? Preferably, I want the default host not to be the same as the ip address host. Now I have something like this:

Obligatory - none of the above worked for me. I inherited strange combination of ip based virtual hosts and * vhosts (not assigned/catch all ips) based virtual hosts in this Apache config messed by ISPConfig.

I wanted Apache to serve not configured hosts with same page. What I had was - not configured hosts went to first vhost after 000-default.conf. No matter I had *:80 catch all defined as first vhost, instead of default Apache would load first defined site:

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

Although it's not completely valid config, what finally worked was adding ip based virtualhost without ServerName/ServerAlias defined:

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html


        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html
        SSLEngine On
        ...

$ apachectl -S outputs ip based vhosts first, and * based vhosts later, and finally my default site is loaded before real site:

         port 443 namevhost server.tld (/etc/apache2/sites-enabled/000-default.conf:38)

*:80                   is a NameVirtualHost
         default server server.tld (/etc/apache2/sites-enabled/000-default.conf:1)
         port 80 namevhost server.tld (/etc/apache2/sites-enabled/000-default.conf:1)

Word of notice - in config like this, * vhosts won't work, so you need to apply ip's to all vhosts.
