What’s wrong with the VirtualHost

I have the following VirtualHost

// filename: /etc/apache2/sites-available/ccbbbcc

<VirtualHost 1.1.1.1:80>
     ServerAdmin utopia@ccbbbcc.com
     ServerName ccbbbcc.com
     ServerAlias www.ccbbbcc.com
     DocumentRoot /srv/www/ccbbbcc/production/public_html/
     ErrorLog /srv/www/ccbbbcc/production/logs/error.log
     CustomLog /srv/www/ccbbbcc/production/logs/access.log combined
</VirtualHost>

And then I also have

//filename: /etc/apache2/sites-available/default

<VirtualHost 1.1.1.1:80>
ServerAdmin webmaster@localhost

        DocumentRoot /var/www/
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
blah blah blah

How come when I type into my browser http://1.1.1.1, it takes me to http://ccbbbcc.com ? Even when I point new urls to the IP 1.1.1.1, webpages serve from http://ccbbbcc.com. Why am I unable to serve pages from /var/www directory?

Additional symptoms – the ccbbbcc vhost overrides only SOME of my other vhosts. Not all.

Additional Notes

I've made sure to use a2ensite and to restart apache.

This is what my /etc/apache2/ports.conf looks like

NameVirtualHost 1.1.1.1:80
Listen 80
Listen 443

I made a file called /srv/www/ccbbbcc/production/public_html/test.html with the text "Hello World". When I type http://ccbbbcc.com/test.html, the page loads fine. When I type http://1.1.1.1/test.html, I get a 404 Page Not Found. When I type http://1.1.1.1/, the web browser refreshes and then displays the url http://ccbbbcc.com. I then append test.html to the end of the url, and the Hello World shows up again.

So does that mean there's an http redirect happening somewhere? If so, I can't seem to determine what's causing it.

Also, i notice ccbbbcc overrides SOME of my virtualhosts, not ALL. There doesn't seem to be a pattern to which vhost is discriminated/overridden.

I also noticed that if I do the following

1. a2dissite ccbbbcc
2. /etc/init.d/apache2 reload
3. a2ensite ccbbbcc
4. /etc/init.d/apache2 reload

Then all of a sudden, http://ccbbbcc.com serves pages from /var/www/, and http://1.1.1.1 also serves pages from /var/www. How come the a2ensite/a2dissite of affects where pages are loaded from? The only way to make ccbbbcc serve pages from /srv/www/cbs/production again is to reboot my entire linux server! What's going on?
