Not sure if Charles is changing his DNS while we're looking it up, but I 
got different results:

     $ nslookup chaslinux.com
     Server:     10.10.10.1
     Address:    10.10.10.1#53
     
     Non-authoritative answer:
     Name:   chaslinux.com
     Address: 50.116.61.78
     Name:   chaslinux.com
     Address: 2600:3c03::f03c:91ff:fe73:e9fa

I get the same address (both legacy and v6) for comprec.org and 
fasteroids.ca.

Apache with multiple virtual hosts will pick the vhost based on the 
request url if possible. However, the first vhost is used if the domain 
doesn't match. So I could point charles.chrisirwin.ca to the above 
addresses, and probably get the same drupal landing page.

If you want an error page for unmatched domains (or a redirect to a 
"default" domain), you'll have to make a dummy vhost with a name like 
0-dummy.conf or something so it gets loaded before your other vhosts.
