Absolutely correct. CNAME = EVIL.
Also, another thing that I would avoid is using a box as its own
resolver. ie: in the TCP/IP nameserver settings, don't put in 127.0.0.1
or the box's own IP address. Use a dedicated (reliable!) resolver.
Pretty much every ISP provides resolvers for customer use. We provide
no fewer than 4 local resolvers for our colocation and dedicated server
customers, and of course they're free to use any external resolver
(4.2.2.2, 8.8.8.8, etc) they would like.
